I'm new to the whole game of owning a Cetme and I am aware of the bad reputation with Century. I am having the issue where when the bolt carrier group is fully forward it is impossible to pull the charging handle all the way back without hitting the stock on the ground and pulling down. I have checked my bolt gap and measured .013-.014. Am I missing something else? I have researched the cocking tube gap issue as well but don't fully understand how to check it. Any help would be great.
