Help!! Troy bravo battle rail!

[Cwalk4040]

Hey guys have a sig m400 and just had a troy trx barrel but put on it. When I get home to put on the trx bravo battle rail I slip it on but can't rotate it the 5 degrees to make it flush. If anybody has experience with these you will know what I'm talking about. What's the problem here?

Looks like you need to pull the gas tube back out, pull the rail off the barrel nut, put it in a vice and use your barrel nut wrench to spin the nut one more tick clock wise. Then you should be good.

The nut should be at 35 ft/lbs. I would not move it as long as the gas tube is aligned. Make sure the bolts on the rail are loose. It should rotate correctly. Looks like you have the rail reversed. http://www.youtube.com/watch?v=dejepDnTmC4

It was the troy brand barrel nut. I put a standard barrel nut back on it and it works now.
