Hey guys I have a CA M24 that is about 90% upgraded with only a new barrel and a new trigger to go. I finally put everything together on it and when I want to push the bolt home it would not go all the way back into the gun, leaving about 1cm gap; preventing me from lowering the bolt handle. I can push the bolt home if I give it a good smack but obviously this is most likely damaging something. I have messed around with the trigger adjustment a bit, but the problem is still there. I plan on getting a new trigger but I would like to know what is causing the problem because I have been told that the stock trigger is very good.
