AIRSOFT HFC M11A1 King Arms Rail Kit Clone

thingiverse

Behold... my take on the King Arms rail kit. This can be yours for less than $5 in materials and filament, meanwhile King Arms wants several hundred dollars. The only hardware required is a single M4x8mm hex screw. No modifications are necessary to fit this kit onto your M11. Assembly is tricky since we are trying to retain the gun as stock. In order to install it, you will need to put the blowback housing, recoil spring, and metal guide together in one piece. Screw the M4x8mm into the blowback nub, and snap it into place on the blowback unit. Then, as one solid unit, push it into the frame, with the nub being pushed into the large diameter hole on the inside of the unit. Once there, bring the nub forward a few millimeters, to line up the blowback nub screw with the hole on the top of the body. Place your allen key in the hole, unscrew the nub screw all the way, then insert the handle into place. Screw the nub screw back down all the way, then installation can proceed as normal.
