hey new to the fourms.
just got myself the open (pull) bolt long version of this gun from a buddie that was having problems with it. (full auto would putter and drain all the gas). after some tinkering i found out that the trigger box just has to much stuff in such a small space. the hammer has a small latch that was grabbing the sear every other shot(when on full auto).
notice the latch on the hammer circled in red and where it was catching in blue. but after sanding off that latch on the hammer the gun now works fine. Now if only i could find out why my nozzel is freezing so fast.
P.S.
