When first introduced in 1956, the AR-10 used an innovative combination of a straight-line barrel/stock design with phenolic composite, a new patent-filed gas-operated bolt and carrier system and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over 1 lb (0.45 kg) lighter than other infantry ...
The Barrett M468 rifle employed the same Stoner bolt and carrier piston system as the M4. [6] The weakness of such a system is that it distributes hot gases and unburnt propellant directly into the rifle’s receiver, leading to overheating and potential stoppages if regular maintenance and cleaning protocols are overlooked.

The sheet metal construction and the design of the bolt, bolt carrier, guide rods and the weapon's disassembly showed strong similarities to the Armalite AR-18 which was manufactured under licence from 1975 to 1983 by the Sterling Armaments Company of Dagenham, Essex, [7] [8] [page needed] and which had been tested by the British Ministry of ...
In November 1947, the new prototypes (AK-47s) were completed. The rifle used a long-stroke gas piston above the barrel. The upper and lower receivers were combined into a single receiver. The selector and safety were combined into a single control lever/dust cover on the right side of the rifle and the bolt handle was attached to the bolt carrier.

To improve reliability, Colt used an articulating link piston (ALP) which "reduces the inherent stress in the piston stroke by allowing for deflection and thermal expansion". [1] In traditional gas piston operating systems, the force of the piston striking the bolt carrier can push the bolt carrier downwards and into the wall of the buffer tube ...
