Carbine-Length Gas System
Carbine-length gas systems are typically found on M4 Carbine clones or other rifles with similar barrel lengths. For simplicity's sake, this page will include any gas system that is shorter than a mid-length gas system, thus M4 clones with 14.5in. (37cm) barrels and even carbines with only a 7in. (17.75cm) barrel will be featured if one happens to be reviewed. Carbine gas systems are typically found on SBRs (sub-16in. (40.6cm) barrels), but can also be found on M4-style rifles with 16in. barrels if the owner prefers the shorter gas system/M4 Carbine look without having to register the firearm as a short-barreled rifle (SBR). Carbine-length gas tubes are generally 9.75in. (24.7cm) in length and use 7in. (17.8cm) handguards. Listed below are the various rifles that have been reviewed with a carbine-length gas system.
