BCA barrels?

[Drillboss]

My next step is to take my home built upper apart and re-bed with Loctite. I originally just used grease. I can't pass judgement on the BCA barrel until I try this.

Maybe I'm reading this wrong, but I wouldn't loctite the barrel nut. I've never seen anything recommend that.

BTW, for bedding the barrel extension into the receiver, I've always used the blue. You can knock that loose with a wooden dowel later if you need too.
