While cleaning and checking a few things on my new rifle I noticed a small gap at the top of barrel between the gas cylinder lock and the gas cylinder. After removing the gas piston for cleaning I tried to loosen the lock by hand to see if it was tight. I used my tools to loosen the lock it was very tight, clocked at 3:30 for hand tight. I looked at the gas cylinder and just pulled it off with little resistance, there was a lot of blow by around it.
I replaced the gas block with a unitized part I had on hand and fitted a different gas lock to clock at 5:00. When I finish tightening it the gap wasn't present. I will see if there is a difference at the range later, here are my questions.
1. I have never seen a gas block that loose, usually have to use a wooden dowel to remove them. Is it common to see them this loose.
2. Could the gas lock being too tight affect accuracy?
