So I have a Troy PAR in .308 that has a TRX front hand guard/rail. I bough a 2” QARS Rail section to attach to the rail- but cannot figure out how to do it! I’ve read the instructions, but there’s raised ribbed material on the inside bordering each mounting hole!
Surely someone here has a Troy Alpha rail on their AR, or a PAR... how do you attach the accessories to the holes?
