zunooo45 Posted March 18 Share Posted March 18 I picked up a single-trigger coach gun and immediately polished the mating surfaces of the foregrip and receiver. I still need to disable the auto safety and possibly lighten the lever tension spring. When the gun is cocked and the lever opened, the barrels drop free. When the gun is not cocked, the is enough resistance to keep the barrels from fully dropping. I haven’t seen much information on this in my internet searches. Do I need to polish these pins and shafts? Quote Link to comment Share on other sites More sharing options...
