    Ok, I just got home with my new RRA Entry Tactical, and I'm trying to get the upper & lower together. Got the pivot pin in; the takedown pin is proving a bit more vexing. The manual says it's a tight fit at first (an understatement). It appears the upper is going all the way in, and I can get the pin all the way through the upper lug, I think. Getting it back through the other side of the lower is the problem. I don't want to take a hammer to my new rifle. Some people on ar15.com said you should apply grease or oil.

    Is this what I should do? What kind of grease or oil?

    A good oil will always be more slippery than a good grease. Grease is only for places where oil would get flung off.

    As far as what type? How about gun oil? ;)

    Break Free, Hoppes oil, Miltec, FP-10, etc. Take your pick.

    It sounds like something is slightly out of spec. You could tap it in with a screwdriver handle. Working it closed and open a few times might loosen it up. Don't go go Magilla Gorilla on it though.

    You may want to try a different brand takedown pin (try an RRA if using DPMS, etc). I had a problem like that once. I swapped the different brand parts between two different guns and it went away.

    www.adcofirearms.com sells RRA parts
    www.midwayusa.com sells DPMS parts
    www.brownells.com sells Colt (and DPMS) parts
    www.bushmaster.com sells.. well Bushmaster parts of course.

    Are you sure the the upper and lower are mating together properly? RRA uppers have a rep for occasionally been very tight fitting when new. Make sure the upper and lower are fitting flush together. Look through the pin hole and make sure everything is lining up properly. Some light taps with a rubber mallet might help seat the upper, but don't beat on it too hard. Call Rock River if you can't figure it out and they'll advise you on what to do.

    A buddy of mine bought a new RRA varmint rifle a couple of months ago and the upper was so badly screwed up it couldn't be fired and had to be returned to RRA for repair. The rumor is that, with the threat of a renewed AWB ban looming on the horizon, RRA is making new guns so fast their quality control has gone all to hell recently. Hopefully, you're problem isn't quite so severe.
