So, I finally had a couple SBR's approved and went to mate one of my uppers to the lower.
I'm trying to drop a Rainier Arms forged upper onto an Essential Arms lower. Unfortunately, the holes just don't match - It's definitely the upper...It just is what it is. So, I've come to the conclusion that I need to drill out the hole. The rear hole aligns perfectly when it's locked in, it's stupid tight but, there's no resistance on the bolt so, I was going to drill out the front hole a bit. I don't want to redneck it too bad, should I start with a sanding wheel and the dremel? Or just go at it? Anyone have experience with this? It's actually off by a legit sixteenth. Thanks |

A friend of mine drilled his out when faced with the same problem. I'd send the upper back if possible. Purchased well over 9 months ago - Sat in a box until I got the stamps and put everything together, yesterday. As long as I just go horizontal, I can't imagine why there would be any issues, especially considering how tight the rear is... Anyone else? |

I would find a machine shop with a milling machine and have them jig it up and mill the front of the hole. Otherwise it is going to look like bubba got ahold of it and if you ever would want to sell it who is going to buy bubba upper. But, I do like the jig idea. |
