just recieved a set of 3 gas bushings. can any of you that have gone through installing these, I'm wondering just where to start, sizewise. what size did you find worked best for you? just need a good starting size.
Undo the gas block screws after you have disassembled the stock and action. The stock bushing should drop out of the gas block, it also holds the gas pipe in. Replace with a new size and line up the gas pipe to the bushing slot, attach back to barrel.
