removing tight fit barrel

[polydeuces]

Hmmm. I just put together a 300 Blackout and now you have me worried. I was using a BCM upper receiver and a Noveske 14.5" barrel. I had always heard that BCM upper receivers were tight but when I installed the Noveske barrel it slid in no problem. It wasn't loose as in rattling around but it wasn't tight by any means.

Absolutely no worries-its the norm-
Frankly the case with most uppers/barrels in my experience, with some bit tighter than others.
With that said, BCM uppers are indeed consistently tight where heating up the receiver is needed for install.
Full disclosure; based on a sample of 2.

I don't know where you heard that, but it's complete BS.

Did BCM mate the barrel to the upper with green loctite?
I have heard they do but I am not sporting enough to remove on of my barrels just to find out.
