This is a representative example of a restored "Gas Trap" M1 Garand Semi-Automatic Rifle. An early iteration, the majority of the features that would be seen on the full production Garand were in place with the exception of the gas system; a gas trap, a small extension mounted at the end of the muzzle, captured gases as they were escaping to drive them into the long piston assembly to cycle the bolt, was used in place of the port system that would become the de-facto standard for gas operated weapons. While the gas trap had a number of issues, it was an important developmental step from bolt action weapons to the semi-automatic "battle rifle" that would dominate mid-20th Century warfare. Blade front and adjustable peep rear sights, with the stainless steel gas trap/cylinder assembly serving also as the front sight base and a "BATTLE RANGE" marked elevation adjustment knob. The right side of the barrel is marked with "P" and "X" stamps, and the interior of the receiver shows welds consistent with the alteration to correct early Garand stoppage issues. Components are marked as follows; front sight: B 8882, muzzle device: B8876, reproduction gas cylinder: D 28289, forearm: C46006, op rod (uncut, with early "square wire" spring): D 35382- 0, bolt: D 28287/-1/J3B, rear sight cover: B-8872 ,trigger guard: C 46025, housing: D 28290, hammer: C 46008, safety: C-46015, follower arm: B8869, receiver leg: D 28291.
