Hey guys,
This is my first post, and I hope someone can help. I just purchased a Tac Star side saddle for my M4. I removed the trigger group pin and replaced it with the saddle retaining screw. My problem is if I tighten the screw completely it affects the motion of the bolt. If I tighten it reasonably tight, not wiggling but snug the gun functions fine. Should I worry or if the gun is functioning leave well enough alone. I check it's tightness every time out??
