Nice gas ring. does what i expected - Kaw Valley Precision AR-15 One Piece Gas Ring

Aero Precision nickel boron BCG. 1st time with a one piece ring. I thought I'd give this one a try. While the odds of all 3 gaps lining up at the same time are extremely low, this makes them zero. Good ring and also a quick solution if you need to replace. Good tight fit when new ( like a new set of rings should be...) I always keep a spare set on hand. 1800 rounds through and the BCG still passes the "stand up" test. Standard rings were a lot looser at 1500, but the gun shot just fine then too. So it's up to the user, but rings are a low cost wear item so remember to replace. I have never had any issues with individual rings so the cost vs quantity is up to the user as well.
Not difficult to install or remove. Just take your time.
Happy shooting.
