So I was out shooting my BCM midlength for the first time in a while today. All was going well until I put the suppressor on. Within 10 rounds, it had failed to go into battery all the way. I looked in the action, didn't see anything obvious. Ran the charging handle once, same issue. Ran it again it again and it went all the way into battery and then was a single shot straight pull bolt action, seems to be getting no gas at all. Looking at some of the brass fired with the suppressor, some of the primers were blown out. This is British surplus Radway Green that I've had in the closet for years. Everything fired without the suppressor looked normal and has in other rifles, EXCEPT, I think this happened once before with this ammo (without the suppressor) Packed it in and went home. Looking at the gas tube, seems to be in the right spot. Looking into the carrier key, and compared to another one, it appears to me that one of the primers got stuffed into to the gas key. I can't imagine the odds of this happening; it must be pretty amazing. Shining a light in there, it just appears to be closed off in a shorter distance than others from other rifles. What I can see appears to be the size and shape of a primer cup expanded to fill the gas key. So, if this is the issue, what happens... carrier key replacement? Can I get the new key staked properly? What is the torque spec on the two bolts? Any other tips? Will have to google around on this one for a bit.... can't imagine the odds of this, but also can't imagine what other possibility there is at this point. I've compared the gas tube position to other functional guns and it looks to me like it hasn't moved. Thoughts welcome.
