Finally got her, hope to have a range report after the weekend. Fit and finish on the Rock is outstanding. Weight is not bad at all and it is balanced perfectly. It was well worth the 2 month wait. Hopefully she will like some of the 50, 53, or 55 grain loads I have worked up. BTW, the RRA NM trigger is outstanding.
RRA ATH Carbine
18" Bead Blasted Barrel
Chromed bolt carrier
ERGO Grip
Magpul PRS
Primary Arms mount
Nikon M-223, 3-12x42 with Nicoplex
-Still need a bi-pod adapter, just put it on for pics.
Took her out Saturday and was very impressed. Everything I tried shot sub MOA. It really liked the 55 gr Sierra Blitzkings over Benchmark.
Below were the best two loadings (24.2 and 24.4 grains of Benchmark, WW brass, Rem 7 1/2), two 5 shot groups at the same target at 100. Think I'll keep her. The best factory load it shot was a box of cheap, re-manufactured HSM with 50 grain V-max.
