modify modular kits + a piece of twisted bare wire to hold the ar latch down. basically, I loop the wire around the ar latch and then take the 2 ends of the wire and wrap it under the mech box. AR doesn't move and the wire slides out which ever hole you route it through.

or pack the ar hole with white lithium grease. offers enough resistant and holds it in place but will no hinder it
