I just got my first RRA lower and I have the same lower-to-upper tight fitting problem that many people seem to be experiencing, except that in the picture below is what happened when I tried to remove the upper from the lower. I checked the fit with RRA, Stag, Colt, and Bushy uppers after the damage occured and they are ALL super tight. The first upper (an RRA upper) I tried I had to use a mallet and punch just to get the takedown pin to pop out. I had to tap it lightly until the very end when it required a bit more force to get it to finally disengage completely. Below is a picture of what happened. This is from the VERY FIRST TIME I MOUNTED AN UPPER AND TRIED TO TAKE IT OFF! I expect some difference in tolerances between different manufacturers, but NOT when the upper and lower are from the same company. After this I tried it on all my other uppers (5 uppers total) and that's when I noticed it was tight on every upper I tried it on. What I'm wondering is if the upper is out of spec.

Is there anything RRA can do to help remedy this situation?

My RRA lower fits my CMT upper very tightly as well.  However, I feel its a good fit and better than most.  It was a little difficult to work with at first, however with some oil and a little time and effort it turned into a very, very nice fit.  I do not think the uppers or lowers from RRA are out of spec, I think they are just more towards the spec limits so a nice tight fit can be accomplished.  I too had to use a small punch and hammer with a little force to get the take down pin to break free for the first few times, but eventually it worked out well.

Please forgive me for being honest but your picture really looks as if you simply missed the take down pin with your punch and damaged the lower yourself.

No worries. When I was tapping it out, I was tapping it from the otherside of the lower (the SN# side), trying to open the takedown pin, not close it.The punch I was using was an almost perfect fit for the takedown pin hole, so I know there is no way the pin missed because the hole was being used as a makeshift guide for the punch.

I understand the need for oil and for everything to have a chance to break in and loosen up, but this happened the very first time I mounted an upper to the lower. I had just installed everything onto the lower and was performing a function test. The upper was tight getting on there, but I knew this was common with RRAs, so I wasn't concerned at this point. When I went to disassemble the rifle is when I started having the problems.

The kind of damage evident (we've seen it before) comesabout when someone drives the takedown pin OUT, rather to the open position.
It isn't fixable, unfortunately.
We understand that accidents do happen, but also can't cover that type of situation unde the factory warranty.  What we've done inthe past is offer adjusted pricing on a new lower to the individual who has the damage.
Please contact me or Scott in our sales dept...we can figure something out for you.

Ouch, yeah you never drive the pins all the way through the other side.
