    I've had multiple rear take down pins that were so tight, I needed a punch to remove them however, every single one of them is now loose enough to remove with my finger. Don't worry about it. Guarantee it will loosen up after a few hundred rounds.

    Sage advice here, whatever you do...don't Flitz the pins/holes or any other "bubba" move My wife's BCM/PSA gun was a PITA to get apart until the first 500 rounds or so was through it. A magpul dummy round works as a handy non marring punch if you don't have one already.

    OK, let me clarify my comments here since everybody in this thread seems opposed to the idea of contacting Rainier Arms about it.

    There's a very important aspect of quality control here, and companies generally like to hear about negative feedback so they can improve their QC processes. If you don't give them feedback, not only do they lack the ability to make it right, they may not even know there is a problem in the first place and will keep on procuring receivers that may have a similar problem. By contacting them, you are not only helping them improve their QC, but you are also helping to ensure that future customers do not encounter a similar problem.

    When people don't contact the vendor, before long things start to spiral out of control and people start saying, "This is a known issue with Rainier Arms. Just file a little here and run it for a few more months, and it'll be fine." At which point Rainier Arms is caught off their feet, and all they have to say is, "No customers ever contacted us before reporting a similar problem." And then it all goes downhill from there.

    Contact Rainier Arms.

    Good point. And in this case, since this is the internet, and the OP probably isn't sure if what he has is "normal tight pins" that will break-in with use or an actual problem, your advice does make sense. Certainly a better plan than bubba-fixing it.

    I have a BCM complete that the takedown pins were extremely tight when I first got it. After owning it and putting about 500 rounds through it, and general cleaning, it's smooth now. I'd consider it just being part of the "break-in".

    What problem? Nothing sounds out of the ordinary. Just a tight pin they will loosen up with use. Nothing more nothing less. I'd much rather have a thought pin to start with then a loose pin. Its most likely the anodizing is just a tad to thick in the take down pin hole.

    It's really nothing to report.

    This. Nothing to report. It's tolerance stacking, nothing more.

    I've had a couple of builds where I could almost-but-not-quite drive the takedown pin in. That's the time to consider alternative measures. Then the choice is send it back and wait, or get out the rat tail file and drive on.
