    Would you ever consider reaming the holes in an upper or lower if they didn't line up?

    My Noveske upper doesn't fit on my Spikes spider lower. The rear takedown pin will start but not go all the way through and seat.

    This upper will seat on my New Frontier lower I picked up from 2nd Amendment

    I wouldn't, but I'm fortunate enough to have several I can swap around to find a better fit. I had that issue with LMT uppers fitting my Noveske lowers, luckily I found a good fit with swapping uppers around.

    Ive taken a little material from pivot pin holes on two uppers because they were too tight on various lowers.

    A Core 15 300Blackout upper I have mates with the Spikes lower just fine. The only pain was that I put the trigger group I wanted to do run with the Novekse in the spider.

    And yes, that NFA lower is fantastic. I've seen he still has a few at the local gun shows I've gone too. Something tells me I should grab another one....

    They should match up by definition. Something's not right. Try them both on different other halves.
