Razorback 22LR Beltfed Conversion for the AR15 rifle – Credits go to LSM1213
Tired of stacking up old magazines on your plinker? Lakeside Guns has the solution for you — a beltfed .22 LR.
Correct, the Lakeside Machine has a clever transformation for AR-15 style rifles, called the Razorback. This altered upper receiver allows you go through rimfire ammunition by means of a belt.
Maybe best of all, it requires no alteration to the lower receiver to slap one on. In general, the Razorback gives off an impression of being for the most part a novelty but be that as it may, what the hell, it would so cool to bring one at the range.
