I took my Rock River Arms rifle to the range today to test some of my reloads. I mounted a Super Sniper 16x on her to see what she can do. (Normally she has a TA31F ACOG on her).
I've shot about 1,000ish 55 gr FMJ through her. I bought it used and the previous owner claimed he had 400 rounds through it. The rifle has had no failures of any kind.
It's a plain jane non milspec AR. The barrel isn't chrome lined, it has a 1/9" twist and the barrel is only 4140. It does have that nice two stage trigger.
What? Say it isn't true smak_daddy? Non-milspec? Non-chrome lined 4140 barrel? Only 1/9" twist?
On paper and according to the internet, this gun is the trifecta of tacital fail and evil. The horror....
Now back to the real world.
The gun:
How does she shoot? (These groups were shot back to back, not much cooling at all)
Varget loads with the 69 SMK (50 yards):
RL-15 loads with the 69 SMK (50 yrds):
Looks lke 25.2 grains of Varget/RL-15 is the accuracy node for 69 SMK.
I had a tack driving bolt gun that loved 24.9 RL-15 with Berger 70 VLD. I tried it in this Rock River 1:9 twist and had no problems stabilizing this longer bullet (the Berger 70 gr VLDs seem to be only 0.03" shorter than the 77 gr SMK ) .
I'll likely go to the 70 gr Berger with 24.9 gr RL-15 as I shoot this gun out to 500 metres+. The BC of the Berger 70 gr VLD matches the 77 gr SMK, yet the Berger is lighter therefore it will beat the 77 gr SMK.
For your dollar, Rock River Arms is tough to beat.
