I purchased a Trinity Force hand guard to build an upper using my Rock River varmint barrel and a Rock
River upper.
The barrel nut uses a crows foot wrench instead of the standard barrel nut wrench.
The problem is, the barrel nut only has a clearance of 1.000" diameter and the RR barrel in 1.055" diameter past the gas block. The nut won't go over the barrel. I called TF and they have no solution or answers.
Two questions:
1. Do you think I could remove 0.06" with a dowel and emery cloth or wet/dry sandpaper fairly easily?
2. The barrel nut is steel and I will be removing the surface coating. How do I protect the inside of the nut from rust after remove of the 0.06" of metal? Grease, Oil, Recoat with something else or is it even an issue?
Just don't want to start and eliminate the possibility of a returning the hand guard without knowing I can do it.
