GHK SG 553 Magazine Shell

Mag shell for the GHK 553 airsoft GBBR Holds up to 36 BBs Utilizes standard GHK 553 mag internals and base plate. Requires heavy amount of sanding where the BBs, Spring and follower travel. If it does not load enough BBs it just needs more sanding. Use 220 followed by 400 grit, cut to the width of the channel and using a standard cleaning rod to push the sandpaper through and applying pressure to the curved surface. The follower rails also need to be sanded on each side. Since the internal track needs to be very smooth I have left extra material at the top just before the BB enters the feed lips. Reason for this is if too much is sanded in this area the BBs will get stuck before feeding. GG mags will fit much more snug than C02 mags, some filler may be required (foam?) to stop rattling. Sand area where magazine enters magwell for desired tightness. Drill a hole for GG fill valve if req. Mag is still a work in progress but field tested!
