popilla build kit

Popillia hardware kit• 1-Steel rear reinforcement plate• 2- ⅛" thick 70A neoprene rubber buffer pads• 1- 6mm od mag catch spring• 1- ⅛x1" mag catch pin• 5- M4x50mm socket head screws• 5- M4 hex nutsMagazine catch spring was left uncut so the user can tune to their preferences after cutting in half, so technically you're getting 2 mag catch springs incase the first is trimmed to short while tuning. The second uncut rubber sheet is only necessary if you feel your bolt needs some "extra umph" while sending the bolt home, as bolts vary from manufacturer to manufacturer.
