Colt 6940 Dust Cover Opens Randomly After Closed
Any way to fix this? It typically stays shut for a few hours then open on its own. I recall that the 6940 has a different dust cover assembly as its connected to the monolith upper. Thanks
Defective dust cover (spring loaded detent latch piece block not installed high enough on the dust cover plate, and not correctly engaging the upper receiver detent for it).
Simple solution is to just change the dust cover to one correctly assembled.
