The Robinson Armament Co. XCR is a multi-caliber, gas piston weapon system developed by Robinson Armament Co. for U.S. Special Operations Command (SOCOM) to fill the requirements of the SOF Combat Assault Rifle, [5] or SCAR competition, but was disqualified on a technicality due to late delivery of blank firing adapters.
short-stroke gas piston Short stroke gas piston and bolt carrier group, from a gas piston AR-15. With a short-stroke or tappet system, the piston moves separately from the bolt group. It may directly push [12] the bolt group parts, as in the M1 carbine, or operate through a connecting rod or assembly, as in the Armalite AR-18 or the SKS.
The fourth was the carbine's short-stroke gas piston (“Piston Means for Gas-Operated Firearms” U.S. patent 2,341,005 published February 8, 1944). Winchester felt the earlier Williams patent for his floating chamber gas piston (“Automatic Firearm” U.S. patent 2,090,656 ) was sufficiently different from the design used in the M1 carbine ...
The SIG MPX is a gas-operated submachine gun designed and manufactured by SIG Sauer, and is primarily chambered in 9×19mm Parabellum. It is a gas-operated firearm featuring a closed, rotating bolt. [2] These design features, rare in submachine guns, were chosen to enhance the safety of the user and to have a more reliable firearm. [3]
Firearms with a direct impingement design can, in principle, be constructed lighter than piston-operated designs. Because high-pressure gas acts directly upon the bolt and carrier in a direct impingement system, it does not need a separate gas cylinder, piston, and operating rod assembly of a conventional piston-operated system, only requiring a gas tube to channel gas from the barrel back ...

Carrier tilt is a wear issue that can arise in some gas piston-based firearm operating systems. High pressure gas pushes the gas piston back hitting the bolt carrier. This force pushes the bolt carrier down into the buffer tube wall. This can lead to increased wear, shaved and/or chipped metal. This in turn can lead to a loss of accuracy. [1]
