I recently purchased a universal gas plug for my M1 due to the increasing difficulty in finding M2 ball ammo. My question is this, if I set it properly to handle aftermarket ammo then remove it and put the stock plug back in to fire M2 ball again, can I then replace with the universal plug again without adjusting it since I have already set it? If anyone has experience with this I would appreciate it, I just wanted to get some understanding before tuning in the new gas plug. Thanks in advance.
