Most Helpful Positive Review Rock river 350 upper
Product arrived timely. Fit and finish are very nice. Mounting is line to line with my current rock river lower receiver. Didn’t need to modify anything but fit is very tight, which is consistent with other online comments. Overall very pleased

RR Arms 350 Legend stainless barrel upper

by Bob, Verified Owner from IA, United States Written on July 2, 2026
It shoots really well 1 inch at 100yds. Included magazine works as it should no failures to feed or eject. I don’t know why it is threaded 1/2x36 when 5/8x24 would make more sense. The muzzle break has sharp points on it so you can’t slide it in a case without tearing it up.
Would recommend: Yes

Rock River Arms .350 Legend upper

by Tpr. Jon, Verified Owner from MI, United States Written on May 1, 2024
High quality RRA upper. Fits my RRA lower like a glove. No FTFeed and very accurate with Hornady 170 grain ammo. Both 10 round and 5 Rd mags worked flawlessly.

RRA 350 Legend complete upper

by Chad Johnson, Verified Owner from MI, United States Written on September 4, 2023
Looks great and works spectacular. High quality I expected from RRA and had met all that I wanted it for. Fit and finish in my RRA lower are awesome. I just swap uppers from 5.56 to .350 and I’m ready for whitetail. You won’t be disappointed. There are cheaper, but not the quality.
Pros:
  • Quality
  • accuracy
  • Weight
  • Looks
Cons:
  • None
Best Used for:
  • Whitetail
