this is my a version of the fabled magpul fmg that uses poly80 rails. and is made for glock 19 form factor. i shortened 2in to fit my printer except for the butstock where i had to make a seperate butpad. to leave space for a glock17 slide later on. here are the issues i didnt finish a few parts due to hardware problems in better days i would have made 10 or 20 models this far along in the design but all my printers are down and i have computer issues. i didnt finish buttpad needs glue on pads. the cocking arm is cut at the front and needs to be sized and made one part. needs hole for mag catch spring. and the locking tab on the cheek peice needs work .in the file are a lot of parts i am buliding a whole weapons system around fmg form factor with under gun rail system for suppress fire, remote gun set up with tripods and mounts and more i am trying to make the gun grabbers worst night mare with love. sorry no folding grip on this one . anyone want a 45 10mm large frame folding grip fmg system with better form formfactor and looks than the magpul or zev i do. it would be nice to have 10 20 of these with tripod remote trigger an use common cheap 12volt securty camera system what im cooking is a force multiplyer . if you want in send me some money.
