OFB-INSAS Rifle

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.

FN FAL

FN FAL

The Phrase "Help I've Fallen" got a new definition when the FN FAL arrived. Didn't matter what odds were against you when you had the biggest baddest boy of assualt rifle world on your shoulders. Unlike the AK and AR, the FAL used a s big 7.62 x 51 full size rifle cartridge. The FAL was predominantly chambered for the 7.62×51mm NATO round, and because of its prevalence and widespread use among the armed forces of many NATO countries during the Cold War it was nicknamed "The right arm of the Free World"

The FAL operates by means of a gas-operated action very similar to that of the Russian SVT-40. The gas system is driven by a short-stroke, spring-loaded piston housed above the barrel, and the locking mechanism is what is known as a tilting breechblock. To lock, it drops down into a solid shoulder of metal in the heavy receiver much like the bolts of the Russian SKS carbine and French MAS-49 series of semi-automatic rifles. The gas system is fitted with a gas regulator behind the front sight base, allowing adjustment of the gas system in response to environmental conditions. The piston system can be bypassed completely, using the gas plug, to allow for the firing of rifle grenades and manual. The FAL's magazine capacity ranges from five to 30 rounds, with most magazines holding 20 rounds. In fixed stock versions of the FAL, the recoil spring is housed in the stock, while in folding-stock versions it is housed in the receiver cover, necessitating a slightly different receiver cover, recoil spring, and bolt carrier, and a modified lower receiver for the stock.
