    Put together a new RRA lower with a DPMS parts kit. Installed a BCM upper onto the lower with no difficulties. During a function check I found that a magazine would not seat in the magwell. Inspected the magwell and noticed the upper receiver was not flush with the front of the magwell. Pulled everything apart and compared the RRA with a CMMG lower I picked up recently on impulse and sure enough, the magwells didn't align. The RRA magwell is machined too far forward making it impossible to insert a magazine with an upper installed or have the follower engage the bolt catch.

    A drag :squint:.

    Anyone here had to mess with exchanging a gun or receiver? I am only assuming their warranty is good on a stripped lower given that the installation of the other parts was not relevant to the thing being machined incorrectly.

    Just venting a bit. My new rifle has become an expensive doorstop.

    Don't have any pics. I might be able to get some monday. Looking down the front of the magwell with the upper installed the face of the chamber where the barrel meets the upper extends a good 1/16" into the magwell making it impossible to insert a magazine.

    Old thread but thought I should update it. After messing around for a while trying to rule out other things as the source of the problem, the lower got sent back to RRA. They sent me a new lower without any hesitation. Good service from RRA. I hope to install the parts kit this weekend.

    This. Send them an email asking about it, then send them a picture of the cut up lower like 10 min later.

    It wouldn't lock back with GI or Lancer magazines consistently.

    RRA was contacted and sent me a new lower. I just resurrected the old thread so people would know they took care of the situation.
