I have built quite a few ARs over they years but this one is giving me some problems and I think I know the answer but I want to ask here first.
The gun is a 20 incher with a .920 fluted barrel I was wanting to use my Troy 13.5 MRFX quad rail but this style rail fixes to a stock barrel nut with the delta ring removed. A "stock" barrel nut will not fit over the .920 barrel and so far I cant find anything that would make this combo work any input for you guys would be helpful.
