Matrix Spare Magazine for Custom MK23 Falcon Beta Gas Pistol

"I got this for my stock TM MK23 NBB, and it broke the trigger arm after shooting about 100 BBs. Turns out, the problem was with the Matrix feed lips – they were clamping onto the BBs too tight, adding stress on the trigger pull to feed the next round. Stock TM feeding lips are highly polished puts less strain on the trigger arm. After swapping out those feed lips, everything's works.
