Short headspace with Sabre defense barrel
#5
Ammo does fit the chamber, and the rifle cycles. I have shot ~ 200 rounds of Wolf and it functions fine, but I get the signs of brass flowing on the bolt head. I shot Hornady for the first time last weekend. It chambers fine. With my adjustable gas block turned off, the rifle still cycled. The next shot, the gas block came loose.

With the bolt head recess of .15, does that mean that I have too much headspace? If so, I don't understand why it wouldn't close on a "go" gauge. I removed the extractor and ejector when using the gauge, it wouldn't close. It is weird, but when I went to retract the bolt, it was stuck, I really had to work to get it free.

Maybe my gas block was the problem. Just wanting to make sure I don't blow up the gun.

Thanks!
