I've got plans to shim the hop-up arm to remove that slop. Honestly though its been shooting fairly well so I don't want to mess with it, on the other hand it is overhopping slightly and I'd like to eliminate that.

Sure I’ll post some pictures of the shimming and the set screw.

Basically there is a hole tapped from the top of the rail down through where the gas tube goes directly over the hop-up arm. I managed to get a perfect size set screw that sits exactly flush with the rail which sets the hop-up exactly where I need it.


Can you post pictures of your SCS mod? Did you attach the SCS to the arm or does it sit on top of the bucking loose?
