Really nice handguard that doesn't line up. - Odin Works Forend Ragna M-lok 15.5" Ar-15

Save your time and effort. Just buy a Midwest Industries handguard, which was my plan when I saw and ordered this one.

I really want to like this forend. I really do. However once installed and assembled on the complete rifle, the handguard has a forced 1mm gap between the upper receiver and the rail. I don't know if it's just out of spec and should be this way or what. The barrel nut has a groove in it, which is supposed to seat two set screws that twist in from 9 and 3 o'clock. With the barrel but torqued to 60 lbs. The groove is still 1mm too far forward to allow the handguard to sit back against the upper receiver. I've removed and retorqued the barrel nut to make certain that the barrel is fully seated in the upper and it is.

This is my first and likely my last Odin product. Honestly, a cheap Diamondback firearms handguard is superior to my experience with this one.
