It happened with the safety on.

My rifle is an aero precision ar-10 in 6.5 creedmoor. This is an issue I am having where the gun goes off on closing the bolt. Yes with a bang not just a dent. I was using federal 140 gr ammo.

I recently built an aero precision ar 10 in 6.5 creedmoor as a hunting rifle. I now have a slam fire issue. This is caused by the free floating firing pin striking the primer on bolt release. I don't believe this is a problem in a target rifle when you are sending a chambered round down range, however with a hunting rifle you may not fire a chambered round and intend on re-chambering the round for several hunts. My question is, is there a compatible bcg with a firing pin spring for my build? If not, why isn't this an option?
