Archived [ARCHIVED THREAD] - Poor upper/lower fit RRA lower w/ DPMS upper?
Posted: 4/17/2006 2:43:11 PM EDT
I was assembling a gun and had a problem with a DPMS A-3 upper assy and RRA lower.   When the front pin war installed, the rear pin holes did not line up. The upper seemed to be too far back and the gun would not close.   Has anyone else had a similar problem with this combo?  I am thinking of getting an upper from Del-ton, anyone want to advise on that combo?

USE A HAMMER!!!



no I had this problem along with the RRA hammer will hang up on the DPMS bolt carrier well the back of the firing pin.   it just took a little luvin to make em fit together also had to get a rounded hammer ,  10#'s of luvin to be exact! j/k dont use a sledge hammer on your gun.

That's the combo of my first build. No problems on mine.
