ar magwell screwed-in retainers
thingiverse
Love the magwell but I couldn't keep it from moving and I didn't want to use grub screws. So I countersunk some holes and made some holes in the little retainer clips. You need m2x7 or m2x8 (maybe m2x10 will work?) BUTTONHEAD. You put on the magwell, insert the little retainers 1 at a time and screw the m2x8 in from the BOTTOM. It should not interfere with the mags and you won't mar the lower. I added a file on the right for the type of trigger guards that screw in instead of use a roll pin (aero precision for example).
