Tippmann Arms M4-22 Pro Compact 22 LR 11" 25rd Pistol

The M4-22 Pro Compact pairs an 11" barrel with Tippmann Arms' Compact Bolt System and measures 19.5" overall. There is no brace: a rear Picatinny rail adapter sits where a buffer tube would, and you decide what to mount there. The upper and lower receivers are aluminum.

The 4150 steel barrel has a Parkerized finish and a 1:16 twist, and is threaded 1/2-28 under an A2 birdcage. A 9" composite M-LOK handguard keeps the weight down and gives room for a light or a handstop. The bolt is nickel plated, and the bolt catch and bolt release work just like they do on a full size AR. It also has a functional forward assist, a shell deflector and a working dust cover, and the mil-spec fire control group accepts drop in triggers. Front and rear flip up sights are installed, and one 25 round magazine is included. Most standard AR-15 accessories fit. It makes a short 22 LR pistol for range plinking and AR practice.
