Troy Alpha, barrel pinned and welded at 14.5 with a Surefire brake on it, compatible with their suppressors. with the rare PDW stock this is the shortest an AR can get without being a pistol or SBR. Great car gun.
Comes with one Troy mag, rail attachment and grip. Doesn't come with fire control, I want to keep the binary trigger for a different build. If you want it it's 500$ extra.
