This is the SERBU GB-22, a single shot, open bolt .22 pistol designed to be extremely simple to build, even with basic handtools, as necessity or availability of materials and tools dictates. Because it’s so basic, it also lends itself to as much modification as the builder deems appropriate. For example, the GB-22 doesn’t have sights as part of its standard design, but a creative sort can include irons in the design, or as is the case in the model above, create a mounting platform for an electro-optic. In case you were wondering, the ‘GB’ in GB-22 stands for ‘Gun Buyback’, as creator Mark Serbu has pretty much stated that because of the simple design the GB-22 can be built up quick and cheap and used to game a gun buyback program.
The plans are available right now on SERBU’s site for a paltry $12 (link here). If you feel you’re not mechanically-inclined enough to take advantage of the plans, then you’ll have to wait until SERBU receives BAFTE approval for a built kit.
