Barrel Extension Separation!

[Hansel&Grendel]

The barrel was indeed bored by Criterion with the barrel blank work performed by PF in Martinsburg WVA. Yes, I'm a bit disappointed that I was told that I over-torqued the EFAB and that it was a mistake to use a Geissele Reaction Rod. I've lost count of how many brake/comp installations and builds from ground-zero that I've performed. I don't over-torque brakes/comps or barrels. As said, I clock brakes/comps at 10:30 - 11:00 for a final wrenching. PF is taking care of it, and I've had great success with them in the past, but in all honesty I don't understand how I could have over-torqued without a running start and why it's such a bad thing to use a Geissele RR. I know that Midwest Industries has an upper receiver rod with a removable top piece that fits into the charging handle groove for added stability, but I've had nothing but success with the Geissele RR.
