I bought the 24” 1-8 twist Rock River Varmint upper. Very nice upper. Functions perfect so far. Land all brass at around 3 o’clock. THIS UPPER IS ACCURATE! So far I’ve only shot bullets 68 grains and heavier, but that is why I bought this upper. Loves SMK 77 gr!

20 bull barrel rock river

by T, Verified Owner from NV, United States Written on April 26, 2025
This upper is absolutely amazing. I got it paired with a rifle length buffer system. Almost no recoil and I can keep a 10-in plate floating in the air at 600 yds rapid firing. Heavy as an ar10 but takes forever to heat up

Rock River 20in 5.56 varmint/target AR upper

by Pat, from IN, United States Written on July 24, 2023
Circumstances have prevented me from using this upper yet. Workmanship is good, fit is near perfect and Rock River has an excellent track record. So I have every reason to expect it to shoot well. Optics Planet's service is always impeccable.
Best Used for:
  • Varmints and paper punching
  • Varmints and target shooting
Would recommend: Yes
