It's got a slight incline to it that I can't figure out. In regards to the upper, this is the add where I bought it. ad |

Nice looking AR, but you might want to refit that MI FF tube. Take it off and try it agian. Either the bbl nut is out of spec. (doubtful), or the MI 2 pc FF is out of spec., or you may just have it on wrong. Good luck. If the bbl nut is at an angle (kind of like \ ) then your upper receiver may be way out of wack. I hope that's not the case. Keep us posted. I'd like to hear what's up with it. DBAR edit - Looked at your pictures again. If I had to guess I'd say it was the assembly of the FF tube on to the bbl nut. It doesn't look like it's on correctly. The flats (flush to the receiver) on both sides should be a lot tighter. There shouldn't be that big of a space between the top and bottom parts. |
