Mac11 issue

Dart · September 17th, 2010, 23:10

so I finally got my hands on a replacement rubber for my mac11 hop up. After replacing it the gun cycles flawlessly how ever I am getting about 1 in every 5 rounds that just drop out of the gun in about 4 feet. Any idea what might be going on with this? Is there usually a break in period hop ups? My ak47 gaurder black didn't seem to have this.

Any ideas?

strangely my WE hicappa is having the exact same problem. Its a fresh bottle of propane. Both guns have new hop ups.

is your hop up dry? because its suppose to be really dry. especially on m11's

other than the oil that's made its way through via the fill valve. Now I got the hop up off... I wonder if that's letting the bb roll forward too early and tripping the valve to blow back.... Hmmm.

where did you buy your hop up? is it made for you m11? You can clean your hop with hot water with detergent soap, to clean out the oil residue.

Did you remember the ball bearing (assuming it's a KWA/KSC standard system) that applies pressure down on the BB?

Yeah... could be a missing bearing. Did you remember to put it back in?

If it is in, try turning up the hop-up a bit until it won't roll out anymore.

no bearing in the hfc... That's the only difference between hfc and kwa. Hfc is just a set screw with a cupped end.
