Installing the thermo fit blem upper from BCM was quite a challenge. Took about 10 iterations of cooling the barrel extension under the cold water faucet, then quickly heating the upper receiver, and pounding on it with a mallet to get the barrel in. I also used some green loctite 620.
The barrel is proof research stainless and the extension measured at 0.9995. The inside of the receiver was 0.9990 before ceracote.
Looking forward to some accuracy testing with it because that thing isn't getting pulled any time soon. It wasn't very fun to install!
