I have a one year old RRA EOP Varmint rifle. Great rifle! Just received the following: DPMS Upper Assembly AR-15 A3 Flattop Upper with Bolt Carrier Assembly 223 Remington 1 in 9" Twist 16" Bull Stainless Steel After installing the DPMS upper on my RRA lower, there seems to me to be an excessive amount of play/slop between the upper and lower receivers compared to my complete RRA rifle. If I grab the forend and twist, there is a small amount of movement. Is a little movement between upper and lower assemblies normal? My EOP is rock solid. Thanks for any insight. Cheers, B2AR15 |
I just ran into the same thing. I have a RRA flat top upper and put it on a RRA lower. It is so tight I have to smack it with a rubber mallet to seperate them. This is the norm? I figure too tight is better than too loose. |

Tight is all right as long as parts still fit together without too much friction. he My new RRA lower is also tight. Got a new V-22 upper for it and needed to use some serious force with a brass punch to get the takedown pin in or out! I could work the pivot pin with my fingers and it was just right. A little needle file work on the V-22 upper cured that problem. The new CMT upper I bought is also more than finger tight on the takedown pin, but only needs a little help with a mallot. I figure it'll losen up some with use. |
Yeah, but DPMS uppers (and lowers) are slop city for fit. I too have a DPMS upper on a Continental (who makes the RR lowers) lower, and it's the only set I own with more than a tiny bit of play. The rear lug on the DPMS upper is .003 thinner than the nest thicker upper I have |
| Strange I've got a DPMS upper on a RRA lower and it's rock solid tight fit, without being too tight. Do have to use something more than a thumbnail to pop the takedown and pivot pins though. But as have as overall fit it's as tight as my full RRA rifle and way tighter than my bushies. |
