picatinny rail adapter for G&G RK74 CQB (AEG) side keymod

Picatinny rail adapter for a G&G RK74 CQB AEG riffle.

Design

prints in two parts: the rail and the little spacers/locks

To attach it securely, we reuse the first screw on the rail.

Parts required

4 x M3x8
4x M3 nuts

Printing

• print the rail on its back, picatinny side up
• print those spacers however suits you best. I printed without supports, large/nut side facing down. That does mean you'll have some cleaning to do so the nut will fit, but at least the outside will be neat and there's no impact on strength.
