Not a complete firearm but I did score an 'A2 upper with an 11.5" barrel for my AR15 pistol. Originally it had a 5.5" flash suppressor seemingly pinned and soldered on. In sanding off the finish of the base of the Flash suppressor no pin was found. After cutting and grinding off the flash suppressor(Without fragging up the threads no less) it was discovered that it had been epoxied on. Upper then got a thorough cleaning as inside it was filthy. Once clean it passed a quick 20 round function test with flying brass.
Removing the hand guard indicates that the barrel is a thicker 'A2 style to boot.
