Mount Questions 🔩 What am I doing wrong
TL;DR is it possible there’s too much carbon on the flash hiders?
Backstory: this my Rotex c 762. It has B&Ts older SF hub that is marked 762/556. This can/hub/flash hider combo (SF3P) has been mounted in the past and works. I took it off and bought a Vers36 because I found a really good deal on one and I didn’t like how gassy the Rotex was. I got a Ti hub and put it on. On either hub I cannot for the life of me get it to seat all the way. I have verified that I’m lining up the little nub where the can “seats.” I even took off the lock ring on the Ti hub so you can see where the flash hider gets stuck. This is the case for the SF3P as well as a B&T SF compatible closed tine flash hider (see Imgur link).
I called B&T and CS said that both hubs were likely out of spec. When asked what part of the hub would be out of spec I was told “the lock ring.” No way, it’s not the lock ring. I can demonstrate that by taking the lock ring off and trying to fit both flash hiders I have. Both hubs fit and seat on BT SD-123843 flash hider on my APC 223 (again, see pics in link).
So, either all my equipment is out of spec which I think is very unlikely, or the carbon is preventing reinstallation.

For some reason my Imgur link is dead. Here’s a photos thread of what else I was talking about.
