    OFB-INSAS Rifle

    INSAS (an abbreviation of Indian Small Arms System) is a family of infantry arms consisting of an assault rifle, a light machine gun and a carbine. It is manufactured by the Ordnance Factories Board at Ordnance Factory Tiruchirappalli, Small Arms Factory Kanpur and Ishapore Rifle Factory. The Insas Assault Rifle is the standard infantry weapon of the Indian Armed Forces.

    Insas rifle system has been a very effective low cost solution that utilized the best to offer from three rifle systems, viz. AK47, FN FAL, and the M16.

    The action, long stroke gas system, rotating bolt, and stamped steel receiver gives it the ruggedness and reliability of an AK47, the Gas regulator from the FAL give it the ability to cycle rounds, even if the rifle’s gas piston is clogged. Although It has a stamped receiver, the tolerances are kept significantly tight along with the lesser reciprocating breach axis offset compared to AK, gives it reliable accuracy.

    Although 5.56x 45 Nato attracts a lot of flak from critics, it is the most flat shooting round upto 300 yards, and is effective up to 600 yards. Although 7.62 x 39, the AK round has better terminal ballistics, the rounds justs drops too much. When 7.62 x 39 is zeroed at 100 yards, the compensation at 400 yards is nearly 60 inches making the target nearly disappear from the sight picture( which is the engagement range for IA positions in LOC), With a 5.56 you will have to compensate lesser, but compromise on terminal ballistics which a fair tradeoff, as you are hitting the target (if not completely neutralizing him).

    Insas is controllable in full auto like the m16, whereas FAL becomes an ack ack in full auto and with and ak47 "you spray and pray". When the Insas was introduced, there was no 6.8 SPC or the 6.5 grendel options hence 5.56 was lesser of evil when it came to developing a battle rifle.All these mix and match features gave you a reliable, low cost, accurate rifle borrowing on best features of contemporaries and minimizing drawbacks of the each mentioned systems.

    The Bullpups

    "Bullpup" describes a modern firearm configuration in which the action is located behind the trigger group and alongside the shooter's face, so there is no wasted space for the buttstock as in conventional designs. This permits a shorter firearm length for the same barrel length for improved maneuverability, and reduces weight.

    The Grandpa Bullpup- The EM-2,

    [​IMG]

    Also known as Rifle No.9 Mk1 or "Janson rifle", was an experimental British assault rifle. It was briefly adopted by British forces in 1951, but the decision was overturned very shortly thereafter by Winston Churchill's incoming government in an effort to secure NATO standardization of small arms and ammunition in the face of American intransigence. An innovative weapon with the compact bullpup layout and an optical sight, it used one of the early intermediate cartridges


    French FAMAS

    [​IMG]


    The FAMAS (French: Fusil d'Assaut de la Manufacture d'Armes de Saint-Étienne or "Assault rifle of the Saint-Étienne weapon factory") is a bullpup-styled assault rifle designed and manufactured in France by MAS located in Saint-Étienne, which is now a member of the French government-owned Nexter group. It is the service rifle of the French military.


    The Austrian Steyr AUG

    [​IMG]


    The Steyr AUG (1977) is often cited as the first successful bullpup, finding service with the armed forces of over twenty countries, and becoming the primary rifle of Austria and Australia. It was highly advanced for the 1970s, combining in the same weapon the bullpup configuration, a polymer housing, dual vertical grips, an optical sight as standard, and a modular design. Highly reliable, light, and accurate, the Steyr AUG showed clearly the potential of the bullpup layout.

    The British SA80


    [​IMG]


    The SA80 (Small Arms for the 1980s) is a British family of 5.56mm small arms. It is a selective fire, gas-operated assault rifle. SA80 prototypes were trialled in 1976 and production was completed in 1994.
    The L85 rifle variant of the SA80 family has been the standard issue service rifle of the British Armed Forces since 1987, replacing the L1A1 variant of the FN FAL. The improved L85A2 remains in service today. The remainder of the family comprises the L86 Light Support Weapon, the short-barrelled L22 carbine and the L98 Cadet rifle.
    The SA80 was the last in a long line of British weapons (including the Lee-Enfield family) to come from the national arms development and production facility at Enfield Lock. Its bullpup configuration stems from a late-1940s programme at Royal Small Arms Factory Enfield to design a new service rifle known as the EM-2, which though similar in outline, was an entirely different weapon. The EM-2 was an advanced bullpup configuration rifle, which despite good performance and being officially adopted by the British Army in 1951, never entered service.

    The Israeli Tavor TAR 21

    [​IMG]


    The TAR-21 (or simply Tavor) is an Israeli bullpup assault rifle chambered for 5.56×45mm NATO ammunition with a selective fire system, selecting between semi-automatic mode and full automatic fire mode. It is named after Mount Tabor, while "TAR-21" stands for "Tavor Assault Rifle – 21st Century". Since 2009, it has been selected as the standard issued weapon of the Israeli infantry. The MTAR-21 (Micro Tavor) was recently selected as the future assault rifle of the Israeli Defense Forces, and some infantry division are being issued with the rifle, replacing the bigger and standard TAR-21.

    Modular Combat Rifles


    Bushmaster - ACR - Adaptive Combat Rifle

    [​IMG]


    This rifle in my opinion is the real successor to the Eugene Stoner's M16, most may disagree but the rifle that started out as the Magpul Masada envisioned exceptional modularity, adaptivity and reliability that would have made Mr Stoner proud. Having shot the ACR semi auto, the feel of the rifle is exceptionally close to the AR platform ergonomics. Chris Costa, was heavily involved in the concept for the masada, and it shows in the design, this is a highly functional design and has some features that would make Spec ops teams around the world happy campers, although this product had a recall, I am under the impression that the kinks have been ironed out. This rifle was primarily designed for 5.5 and the 7.62 x 39, for some reason the 7.62 x 39 was dropped by the Bushmaster co and instead 6.8SPC was selected. ACR, the true heir to the M16 is destined to be a world beater (in the ideal world)


    FN SCAR

    [​IMG]



    FN SCAR- Welcome to MK-MOD world...most firearms with Mod xx mkxx in US/Nato nomenclature end up with special forces, and this Rifle produced in two configurations is just that, Special Operations Forces Combat Assault Rifle (SCAR)!!!! FN Herstal initially was on the same bandwagon as the magpul guys and wanted to create a modular system with 5.56 Nato, 7.62 Nato, 7.62 x 39, 6.8 SPC and 6.5 grendel (unconfirmed), for probably the same reasons as bushmaster they decided the final product to just have 5.56 Nato and 7.62x51 nato calibers. The rifle uses a M1 like gas system and fires from a closed bolt atleast for the semi auto version, the version submitted for the USMC stuff was slightly different and used a innovative hybrid bolt system.
    In all this system was envisaged for the spec op forces and will trickle down the chain eventually for spec ops, but seems like it still doesn't have what it takes for being accepted as the main battle rifle.

    Beretta ARX 160

    [​IMG]



    One of the most anticipated rifles in the lineups and competing to be the next infantry rifle for the Indian Army/ IAR US-Army (cancelled) and in service with more than 5 Armies around the world, is true adaptive combat rifle system. Chambered in 7.62 x 39, 5.56 nato, 5.45 x 39, 6.8 SPC. This is a rifle to watch out for, this might be the next big thing. The system capitalizes on ergonomics, reliability and modularity, three traits desired by the most modern armies providing the flexibility of calibers and roles of the modern gunners, essentially a brute force multiplier.

    Heckler And Koch G-3

    The G3A3 (A4) is a selective-fire automatic weapon that employs a roller-delayed blowback operating system. The two-piece bolt assembly consists of a breech (bolt head) and bolt carrier. The bolt is held in battery by two sliding cylindrical rollers that engage locking recesses in the barrel extension (popularly called a "trunnion"; BATF calls this a "mounting block"). The breech is opened when both rollers are compressed inward against camming surfaces driven by the rearward pressure of the expanding gases upon the bolt head. As the rollers move inward, recoil energy is transferred to the locking piece and bolt carrier which begin to withdraw while the bolt head slowly moves rearward in relation to the bolt carrier. As the bolt carrier clears the rollers, pressure in the bore drops to a safe level, the bolt head is caught by the bolt carrier and moves to the rear as one unit, continuing the operating cycle. The bolt also features an anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface. The spring-powered claw extractor is also contained inside the bolt while the lever ejector is located inside the trigger housing (actuated by the recoiling bolt)

    The rifle is hammer fired and has a trigger mechanism with a 3-position fire selector switch that is also the manual safety toggle that secures the weapon from accidentally discharging (fire selector in the “E” or “1” position – single fire mode ("Einzelfeuer"), “F” or “20” – automatic fire ("Feuerstoß"), “S” or “0” – weapon is safe ("Sicher"), trigger disabled mechanically). The weapon can be fitted with an optional 4-position safety/fire selector group illustrated with pictograms with an ambidextrous selector lever. The additional, fourth selector setting enables a 3-round burst mode of fire.


    [​IMG]


    The firearm was equipped with iron sights that consist of a rotary rear drum and hooded front post. The rear sight, mechanically adjustable for both windage and elevation, has an open notch used to fire up to 100 m and three apertures used for: 200, 300 and 400 m. The receiver housing has recesses that work with HK clamp adapters used to mount day or night optics.

    A brief look at Unified Weapon Systems (UWS), an up & coming American arms manufacturer which seems to have recently made it big in Peru, supplying to both their Army and National Police. India's Bangalore-based Tonbo Imaging has been roped in as the preferred bidder for supplying Night Optics like the Arjun uncooled thermal sight, to go with UWS' Peru sales. So once this is done, Peruvian Army will be using Indian-made gun optics.

    http://economictimes.indiatimes.com...ion-to-peruvian-army/articleshow/54804638.cms

    ^^Yeah, no way 100mn is just for TI sights. That's the value of the whole UWS deal.

    UWS product range includes rifles based on the AR-15 platform, and a .50in anti-material/sniper rifle. An under-barrel grenade launcher is also offered but doesn't seem that interesting from where I stand.

    However, I felt pretty unnerved when I couldn't find anything about UWS that did not pertain to the Peruvian deal. I did some digging about their background and they seem to have got some legal issues. Apparently, both the UPR and UCR rifles were designed & engineered by Adams Arms LLC. (which is a far more reputable company IMO. Besides, if you told me the UPR and Adams' Tactical Evo were the same goddamn rifle, I'd believe you), and Adams Arms has filed a case about this issue -

    https://www.law360.com/articles/806615/rifle-co-says-it-was-thrown-from-peruvian-military-project

    Don't know where this case went...but yeah, UWS judicial record is certainly not as smooth as the legs of a little girl.

    @MilSpec Thanks for the article. Very interesting take on the INSAS. Why does it then get so much flak in the media? What are the issues with it?

    One suggestion, You forget the most important thing in all your articles. Paisa. It makes all the difference. Especially to Indians, to make our opinions. Even, if its a rough estimation.
    A rifle can be the best, but if it costs 100x, then you know what Indian army is gonna choose.

    PS: Great Blog, Pity you stopped writing.

    Just for information, french army recently selected HK 416 (a distant derivative of M4, gas piston, havier barrel...) for its forces. Should be derived from A5 version (my baby ;) ) , but with a A2 butt and capability to use barrel grenades (our sin in french army : we love barrel grenades).

    Good choice. The HK416 is a wonderful platform.

    We transitioned from the AG3 to the HK416N and more recently the HK416K starting in 2008. G3 models had one of the most bulky UBGLs I've come across.
