P90 Hi-Cap Magazine Feed Fix

thingiverse

This insert for P90 hi-cap magazines prevents BBs from entering the feeding wheel in the wrong direction, which otherwise prevents proper feeding and causes the spring to unwind uncontrollably. Glue the insert to the location marked on the photo. Tested with King Arms and Pirate Arms magazines. King Arms P90 Hi-Cap mags are very reliable once you figure out the do's and don'ts. I usually make 35 half-turns winds which is enough to for a full magazine of BBs. By over-winding it, the force is too strong and it often unwinds on its own, and you risk the spring to break.
