5 56 Insas Rifle Manual

Rifles, Cartridges found missing in SAPB Battalion: CAG report
Thiruvananthapuram, Feb 12 (PTI) In a shocking
revelation, the Comptroller and Auditor General (CAG) of India
has found shortage of 5.56 mm INSAS rifles and 12,061 live
cartridges in a joint verification held in the Special Armed
Police Battalion (SAPB) here.
The report on General and Social sector for the year
ending March 31, 2018, was tabled in the Kerala Assembly on
Wednesday.
The CAG report also found that anti Maoist operations at
Palakkad, Malappuram, Idukki and Wayanad suffered due to
dependence of police forces on analog communication equipment.
The state government, it said, had 'failed' to make
timely payment of spectrum charges and obtain license from the
Union government for procuring Digital Mobile Radios.
The audit found that the stock register and related
records of arms and ammunition in the SAPB were 'not properly
maintained'.
'The entries in the stock registers had many over
writings, use of white correction fluid and striking off of
entries etc.
The entries and corrections were not properly
authenticated.
Audit could not find any evidence of conduct of periodic
physical verification by higher officers from the records
available at SAPB', the report said.
A joint verification was conducted on October 16, 2018 to
test check, including physical verification, in the battalion
to assess whether physical stock of arms and ammunitions
matched with the stock registers and whether the system of
accounting of arms and ammunitions was 'robust and reliable'.
The verification conducted in the Bell-of-Arms of SAPB,
along with the Assistant Commandant, revealed shortage of 25
numbers of 5.56 mm INSAS rifles and 12,061 live cartridges.
While the police department was aware of the shortage in
ammunition, it 'attempted to cover up' the shortfall instead
of identifying and taking action against the culprits
responsible for the loss of ammunition, the report said.
It was also found that the shortage of 250 numbers of 9 mm
Drill Cartridges was sought to be covered up by replacing the
same with 250 dummy cartridges.
There was no document on record to show how these dummy
cartridges came into the possession of the SAPB and how these
were taken into stock.
The report recommended that in view of the serious
security implications, Government should take urgent steps to
trace the missing cartridges and rule out the loss of rifles.
It suggested that similar stock taking of arms and
ammunition be undertaken in all battalions and police
stations, including Police Chief Stores immediately.
The report also came down on the state police Chief and
said the official violated the MPF (Modernisation of Police
Force) scheme guidelines, which prohibits procurement of
vehicles for VIP/VVIP security utilising the MOPF funds.
The police department procured two bullet resistant
vehicles to ensure security of VIPs, VVIPs and Z+ category
visitors to Kerala at a total cost of Rs 1.10 crore without
inviting tenders as required under the Stores Purchase Manual.
The objective of providing increased mobility to the
police forces as envisaged under the MOPF scheme would have
been achieved had the police department procured bullet
proof/mine proof vehicles for deployment in naxal infested
areas rather than acquiring bullet proof cars for VIP
security, the report said.
The state police chief diverted Rs 2.81 crore meant for
construction of Upper subordinate staff quarters for
Rar program for mac. construction of villas for SPC/ADGPs, it said. PTI UD APR

You could not forlorn going later than book accrual or library or borrowing from your connections to read them.

I thought it'd be a good opportunity to dissect the INSAS and dispel some myths and misconceptions about it.
So with the two line preamble, I take great pleasure in presenting to the gun community, a modest Technical Treatise of the INSAS Rifle 5.56mm 1B1. The specimen in this study was factory fresh and manufactured by the R.F.I (Rifle Factory Ishapore), West Bengal.
To start with, we shall touch up a bit on its pedigree. Common misconceptions of the INSAS's origins and designs range from it being a Galil clone to a hotch-potch of the FAL, M-16, AK & G3.. none of these are in-fact entirely accurate.
The evolution of the INSAS, in fact, closely follows the development of FN 5.56mm Rifles/Carbines with an added Kalashnikov flavor to aid cheap and mass production.
I think one can clearly see why the notion of an FAL gas system clone appeared and stuck on. The early developmental versions of the INSAS sported a gas block and fore sight assembly very similar to the FAL and the SLR1A. The Gas plug design is a common to all. However one should remember that the ill fated FN CAL 5.56mm Rifle was a developmental design that included numerous design features from the FAL. Thus in relation to the scale involved (7.62mm to 5.56mm), the more obvious conclusion would be that the early to mid developmental INSAS rifles borrowed the Gas block/plug/Fore sight assembly from the FN CAL..and not the FAL. Thus the FAL influence ends with the prototype INSAS and not the current issue/production version. The picture below, which I cobbled together, was sourced from various net sources- you can see the obvious relations.
http://i207.photobucket.com/albums/bb31 .. _INSAS.jpgHowever, since then, they(FN) incorporated a few changes, most probably (as I see) with a view to simplify manufacture. The current FNC is essentially a very simplified FN CAL, with improvements and design elements altered to suit quick and less expensive manufacture. The gas block & fore sight assembly was simplified to be made from simple forgings or investment castings with the minimum possible machining operations. The current production INSAS 1B1 sports a virtual 100% clone of the assembly. Take a look at the picture below for a comparison of the FNC and the INSAS.. also note the general similarity of the entire fore end and the muzzle piece.
http://i207.photobucket.com/albums/bb31 .. CINSAS.jpgThe FNC in the above picture is a civilian version with no grenade launching facility or a bayonet lug. Below is a comparison of the muzzle end of the standard military FNC and the INSAS IB1. Note the identical NATO standard 22mm diameter muzzle brakes and grenade launching split rings on both the guns. This seems to be an entirely export oriented feature on the INSAS as I'm not aware of the Indian Army using rifle grenades of this type. The muzzle brake with a radial series of 3 circular ports is common to the INSAS, FNC the CAL and the FAL..
http://i207.photobucket.com/albums/bb31 .. litary.jpgThe gas blockage for grenade launching is achieved by rotating a sheet metal bracket/latch that folds away behind the fore sight post. This is called an 'Alidade'. Rotation is approximately 90 degrees. This is identical in the FNC and the INSAS. The one on the INSAS is made of a very flimsy half mm sheet.. it's actually flimsy enough to deform slightly every time you rotate it. The pictures below illustrate the Alidade in both positions.
http://i207.photobucket.com/albums/bb31 .. 5552-2.jpghttp://i207.photobucket.com/albums/bb31 .. 5553-1.jpgThe top edge of the Alidade has a 'v'notch that becomes visible when it is raised to the gas-blocked (grenade launching) position. This can be aligned with a 'foresight' bead on the grenade to 'aim' the projectile. The picture below illustrates the V notch.
http://i207.photobucket.com/albums/bb31 .. C05554.jpgThe Immediate area behind the Gas block & Fore-sight assembly houses a gas regulator (Circled area in image below) It operated in the same way the FNC does but the lug and locking plunger has been shifted to the front. In the FNC this is in an extension of the breech trunnion just above the chamber. It has two positions Low and High. Default setting is Low.(11'oclock as in the picture below)
http://i207.photobucket.com/albums/bb31 .. ulator.jpgIt is commonly believed that the cocking/charging handle of the INSAS is a copy of the H&K G3/HK33/53 series of rifles. The H&K influence goes only as far as the positioning of the cocking handle - i.e. Ahead of the breech, left side 11 o'clock position with the muzzle away from you. In execution, the design is a virtual lift of the charging handle assembly of the 7.62mm SLR 1A. This has been achieved by extending and re-contouring what would have been the rear sight base one the AK/AKM, about 4 inches forward. The 'T'-slots for the cocking slide is machined on to this trunnion extension. In my opinion this seems to have complicated the manufacturing process because of the added machining operations. Also you cannot rotate the cocking handle to lock back like in the H&K rifles. In its rear most position the slide interferes with the opening and closing of the pivoted receiver cover. The picture below illustrates the relationship between the three rifles types.
http://i207.photobucket.com/albums/bb31 .. Handle.jpgMoving on rearward to the mid section of the INSAS, one can see an unmistakable AKM/Kalashnikov influence. The receiver is of pressed sheet metal of approximately 1mm thickness. It follows the traditional boxy AKM type receiver design with the prominent dimple over the magazine well. The dimple on the INSAS is more angular than that of the AKM. Below is the right hand side of the receiver. With a prominent SLR type carrying handle that's redundant and hardly ever used. Personally, I think this feature is a useless money sink in a 5.56mm rifle. Also missing in the INSAS is the large AK type selector lever. This has been substituted by a virtual clone of the FNC selector lever on the left side of the receiver.
http://i207.photobucket.com/albums/bb31 .. SRight.jpgUnlike the 7.62mm SLR-1A, the carrying handle in the INSAS is an elaborate spring tensioned type. This greatly increases the number of parts and machining operations for a part that's next to being a useless appendage. See the image below.
http://i207.photobucket.com/albums/bb31 .. Handle.jpgBelow is a picture of the left side of the receiver. Also note how crude the lettering is- looks to be scratched on by hand!!
http://i207.photobucket.com/albums/bb31 .. 5560-1.jpgThe primary difference in the receiver design is with the trigger axis hump in the INSAS. The Trigger mechanism is a virtual copy of the FNC. That being said, the FNC mechanism is very loosely based on that of the Kalashnikov. The FNC trigger mechanism design necessitates a lower trigger axis and thus a greater depth of the receiver. This would however have resulted in an awkwardly bulky receiver. The downward hump probably resulted from this need. The picture below gives an idea of the receiver design and the position of the trigger axis of the three rifles.
http://i207.photobucket.com/albums/bb31 .. SASFNC.jpgThe INSAS 1B1 has three modes- Safe, Semi and 3round Burst. The selector lever is identical in position to that of the FNC and is a well though out adaptation on an AKM type receiver. The design of the thumb piece is based more on the SLR design rather than that of the FNC. However, it is still not as ergonomic as planned and unless you have thumbs like E.T., you'll need relinquish your firm hold on the grip to actuate the selector. Very similar to the SLR, the safety position is top most, down about 70 degrees and you have semi, then to activate the tri-burst mechanism you'll need to rotate it almost 180 degrees. Take a look at the image below.
http://i207.photobucket.com/albums/bb31 .. lector.jpgThe three round burst mechanism is a sheet metal encased module that sits on the left side of the trigger/sear shoulder. It works by way of a ratchet and pawl lock-work. It is a vitual clone of the FNC/CAL module and at least in theory, independent of the basic functioning of the trigger mechanism. i.e. in case it buggers up, semi will continue functioning. The red circle in the picture below shows the 3 round burst module.
http://i207.photobucket.com/albums/bb31 .. 5568-1.jpgThe rear sights on the INSAS are a generic two position peep type with windage adjustment. This is housed in an investment cast cradle with typical rounded protective ears. The windage adjustment is effected by a knurled windage knob one the left side, and is held in position by a spring loaded plunger on the bottom. A short 3 inch dovetail rail on the top of the receiver ahead of the rear sight assembly serves as a 0.5' interface for mounting scopes and other optical sights. The images below show a detail view of the rear sight assembly.
http://i207.photobucket.com/albums/bb31 .. C05557.jpghttp://i207.photobucket.com/albums/bb31 .. C05558.jpghttp://i207.photobucket.com/albums/bb31 .. C05559.jpgAlso note that unlike the AKMs the INSAS makes extensive usage of rivets. The inner receiver rails(race ways for the bolt) are also riveted on rather than spot welded.
Field stripping is very similar to the AK, albeit ,with some needless complications..no doubt adding to the cost of the rifle. Like any other weapon, ensure that it is indeed empty and there is no round chambered and that the magazine is removed. Cycle the action and visually eyeball the chamber. The cycling action is very scratchy and uneven. Many specimens bind for no apparent reason while manually cycling the action.
The blue circle in the picture below shows the standard AK type receiver cover locking stud. But you can't simply operate it like a normal AK.. you'll have to first press the lock out button (red circle) which is usually very badly fitted and stiff. You'll be able to get the AK type stud moving only when you do so. I can't think of any reason why this unnecessary feature was included..another money sink. Also note in this and earlier pictures, the re-enforcing cap in the rear end of the receiver cover. This is usually a very poorly formed and fitted piece.
http://i207.photobucket.com/albums/bb31 .. erlock.jpgOnce you've got through hurdle of the locking stud, simply lift the cover. It is captive (i.e. remains on the gun) and pivots upwards like the AK74U. The receiver cover is attached to the pivot by a trio of rivets and this joint may be critical to the long term accuracy of the rifle as the rear sights are mounted on the receiver cover. Often this is badly fitted, often bearing on the trunnion locking shoulder. This either results in bent receiver covers or big gaps in the area.
See picture below and take note of the poor plastic to metal fit.
http://i207.photobucket.com/albums/bb31 .. C05566.jpgOnce you've done this, push the recoil spring guide rod forward, up and rearward. Then pull back and up, the bolt carrier/ piston assembly.
The bolt carrier and bolt is an AK clone scaled to suit the 5.56mm cartridge take a look at the picture below.

http://i207.photobucket.com/albums/bb31 .. C05567.jpgNext, you remove the upper hand guard. This is a flimsy piece of plastic thats always getting lost or breaking in two. The front end has 'PULL' embossed on it and you simply grasp the projections on the front end and ..well..pull.
It has two pairs of rounded steel spring tongues that simply clamp over the gas tube. Its either too tight or too loose.. both with individual headaches - too tight and the plastic usually breaks, too loose, it usually gets lost or rattles and dances all over the place.
http://i207.photobucket.com/albums/bb31 .. C05555.jpghttp://i207.photobucket.com/albums/bb31 .. C05556.jpg

Once this is out of the way and hopefully you haven't broken the hand guard, you now prepare to remove the gas cylinder. The short gas cylinder is retained in the trunnion extension by a very AK flavored latch.. which is often too tight. Many rifles have poorly fitted gas cylinders that really prevents the half-cut cross pin and thus prevents the locking latch from closing smoothly. I saw five brand new broken examples. One was missing the latch.
http://i207.photobucket.com/albums/bb31 .. C05569.jpgAbove- The gas tube retaining latch in open position. Note that the Lower hand guard is a direct lift of the CAL/FNC design albeit with an AKM type retaining interface.
Below- The gas tube removed.
http://i207.photobucket.com/albums/bb31 .. C05570.jpgNow you've stripped the blasted gun!
Below- The INSAS basic field strip.
http://i207.photobucket.com/albums/bb31 .. 5571-1.jpgHere's the INSAS with its basic complement of three magazines. 20x3=60 rounds.. er that's just 10 rounds more than what our fathers and grand fathers carried with their 303's into battle 40-50 years ago. This on the whole negates the whole idea of an automatic weapon..
http://i207.photobucket.com/albums/bb31 .. C05573.jpg

A pair of Steyr AUG inspired waffle ribbed transparent magazines.
http://i207.photobucket.com/albums/bb31 .. C05574.jpgMy camera doesn't have decent macro..so I couldn't photograph the cartridge head stamps. Anyway the fodder below is KF 5.56mm..
http://i207.photobucket.com/albums/bb31 .. C05577.jpgHere's how the magazines come packed from the factory.
http://i207.photobucket.com/albums/bb31 .. C05575.jpgI noted at least three different manufacturers of INSAS magazines, and goodness are they flimsy. I recognized at least one of the sub-manufacturers for magazines - Nilkamal - One of the well known names in plastic furniture.
There were several INSAS rifles made by SAF(Small Arms Factory) Kanpur- They exhibited several badly fitted parts.

I thought it'd be a good opportunity to dissect the INSAS and dispel some myths and misconceptions about it.

Below- The INSAS basic field strip.
http://i207.photobucket.com/albums/bb31 .. 5571-1.jpgHere's the INSAS with its basic complement of three magazines. 20x3=60 rounds.. er that's just 10 rounds more than what our fathers and grand fathers carried with their 303's into battle 40-50 years ago. This on the whole negates the whole idea of an automatic weapon..

http://i207.photobucket.com/albums/bb31 .. C05577.jpgHere's how the magazines come packed from the factory.
http://i207.photobucket.com/albums/bb31 .. C05575.jpgI noted at least three different manufacturers of INSAS magazines, and goodness are they flimsy. I recognized at least one of the sub-manufacturers for magazines - Nilkamal - One of the well known names in plastic furniture.
There were several INSAS rifles made by SAF(Small Arms Factory) Kanpur- They exhibited several badly fitted parts.
Take a look at the picture below. The upper one is and RFI made INSAS and the one in the bottom is an SAF specimen. The RFI rifles appear to be zinc phosphated as they sport a very light grey finish while SAF INSAS rifles are darker and presumably iron or manganese phosphate finish. Take note of the white splotches on the SAF rifle- I noticed all the SAF rifles had these. I found out that they wanted to have white paint filled lettering, but the crude scratching that passed off as lettering was too shallow and the lazy buggers at the factory simply squished some white enamel over the general areas and didn't even bother to wipe off the excess!!
http://i207.photobucket.com/albums/bb31 .. C05578.jpgOver all the INSAS rifle is a major disappointment and while this study is purely academic and has no bearing on the end user, I think it's all I've been calling it all these years- An over weight, complicated, over priced, mediocre rifle.
In the end it shoots- fairly accurately and with reasonable reliability but its plagued by shitty quality and needless refinements of dubious value.

Bottom line - we could have done so much better.
For the shooting report- Check the threads that carry Jonah and Devs reports.
