I want to build at least one SBR soon. I have a lower that I want to register but was realy wanting a .40 upper. From the looks of things, the RRA .40 will not be available soon. I have heard so much about shorten .223's and function and reliability. Can anyone comment on the 7.5" RRA .223 upper? Is it relaible (I know RRA and relaibility should never be used in the same question)? Or for an SBR, is the 10.5" a better choice? My plans are a RRA SB upper, attached to my registered RRA lower, EOTech, Troy BUIS and the Magpul CTR stock.... 77Bronc |
