Troy TRX-Extreme check-up

@C4IGrant

I am running the TRX and love it. Never had an issue.

When applying loctite, always make sure to degrease the screws AND the nut.

This is good advice as I have had loctite fail because I failed to do this. I now use Gun Scrubber on anything I’m going to loctite.

Literally the only point about the TRX Extreme rails many people find remotely disagreeable are those two points - mine are the same procedure as Robb, with red loctite.

Once the VTAC flavored 15" is out, I’ll be running exclusively VTAC Extreme and URX rails.

This really sounds a lot like what happens with aluminum rims and steel lug nuts on a car. The heat build up that occurs from the hub and brakes will cause the two to expand differently and become lose…they will need to be re-torqued in a day or two or you take a high risk of having the lugs work themselves off. The install and reinstall method that has been talked about reinforces this theory. You have aluminum rails and steel screws… I believe. I think that if you were to run a few hundred rounds through a rifle and let the heat cycle run its course a few times and then remove and blue loctite the reinstall you would be good to go.

I think the threads are steel sleeves in the rail

I have the rails on 5 different rifles. 15K + rounds and nothing has come loose. I use blue lock tight or rock set. I would never use red lock tight. I used to road race (heat and vibration) and the only time we ever used red lock is when you wanted a part “permenatly” attached.
