Is this lower out of spec or just very tight?
The A1 upper will not fit unless I physically put lots of pressure on it. It seems to bind at the front of the rec. and put lots of stress on the front pin. 
It does the same thing with this upper. 
The upper on my A4 does it too, but not quite as bad. I still can't get the rear pin in without beating it. 
I know these rec. are built at the high end of the tolerance scale, but I was wondering what I should do to get it to work with my A1 upper? I've never had a problem with NDS rec. and I really like this one. |

We machine our lowers to be on the tight side, sometimes it's too tight for a customers upper.
Send it back, along with the upper you want it to fit, and we'll replace it with one that does. 
Include a copy of your receipt for ground shipping and we will reimburse you. |
