The INSAS rifle is based on the famous Kalashnikov AK-47 action, but with many modifications. The basic gas-operated action (long stroke gas system, rotating bolt, and stamped steel receiver) is of the Kalashnikov pattern. The gas system is fitted with a manual gas regulator similar in design to that found on the FN FAL as well as a gas cutoff. The charging handle is positioned on the left side of the forearm; it is similar in position and design to the German HK G3 rifle.
The selector/safety switch is located on the left side of the receiver above the pistol grip, which allows single shots and three-round bursts. The rifle is fitted with a side-folding carrying handle, and either a solid or side-folding metal buttstock. Furniture is made of polymer with the stock using the butt-plate from Lee-Enfield rifles. Standard magazines are made from semi-translucent polymer and contain 20 rounds. Longer 30-round magazines of similar design are available for the INSAS LMG but can also be used in the rifle. The sights consist of a hooded front, mounted on top of the gas block, and a diopter rear, mounted on the receiver cover. The flash suppressor is shaped to accept NATO-standard rifle grenades. It can be fitted with an AKM-style multipurpose knife-bayonet.
The assault rifle version has semi-auto and 3-round burst modes much like the US M16A2. Derived from the INSAS weapon systems, the INSAS Excalibur Mark-I is ergonomically designed with a folding butt and can be fitted with 20 and 30-round magazines. It is also fitted with a Picatinny rail for mounting of opto-electronic devices. The INSAS Excalibur variant, to be used by Special forces, has semi-automatic and full automatic fire modes.
An under-barrel grenade launcher and bayonet have been developed for the INSAS, which are also compatible with the AK-47s used by paramilitary forces.
