Ever removed a G&P barrel nut? G&P really do a good job of over-torquing their stuff because I don't see any threadlock on their parts.
oh god yes their barrel nut is a job and a half to get off. I had to take my G&P War rifle a part. Couldn't get it off using a barrel nut wrench.
I destroyed my cheap AR wrench with it and had to buy an actual expensive one - that nut cost me about 40 quid to remove. Thanks G&P.
