My bet would be on an issue with the bucking. Also, could you post pictures of the bolt problem?
Embed said:You can just buy an upgraded APS2 bolt handle and you'll be fine. I chose upgrading with an APS cylinder setup for my M24 over a CA-style one because the boss at the end of the cylinder is longer and a little more stable.
I believe PDI and Laylax make said bolt handle, I'm too lazy to find you a link right now but don't buy it until either Dutton or I have checked it over if you do want it because apparently you need someone looking over your shoulder telling you which thing to get heheh
