Hop-up adjustement wheel lock?!?
 

Hey guys, just would like to know if there is a way to lock my hop up adjustement wheel seince after shooting a magazine, i always need to reajust because the wheel is turning counter clock wise?

Cheers!

Oring behind the wheel and carry a screwdriver on your rig to keep the wheel snug after you adjust to your hopup prefference.

Good! I tought about it but didn't want to f... Something without confirmation.

If it's an M4 there's a common problem because some models do not come with a washer.
Oring should work nicely too.

Unscrew the little screw that's holding the adjustment wheel on....put a mechbox shim over it...screw the screw back down. Tight, but be careful not to strip the head off the screw.

That should hold it very much in place.
