One of them in the thread was built buy Ranier I believe. And another checked it several times. I think it is most likely issues to the difference in usgi barrel nut sizes making rails like it and Troy have common issues. I do not understand why Troy and fortis would have those issues but have yet to hear of any issues with Centurion rails yet though

I replaced my C4 with the REV for weight savings and extra real estate. I think it is a barrel nut issue from what I've read. Mine is on a BCM 16" middy upper that has been banged around quite a bit and it there has been no movement at all.

Nice looking rail, thanks for the info! I may get it as a replacement for the quad on my GP gun at some point.
