    Gas Rings

    Posted by Shawn on 1st Jun 2023

    I purchased some Colt gas rings from Arms Unlimited. I had to replace the original rings on my M&P 15 sport 2. They are pretty tight fitting but they work,2000 rounds later and zero malfunctions.

    Gas Rings

    They look like high quality rings. No way to know they are genuine Colt though. However, I tend to trust Arms Unlimited. They aren't going to pull one over on you. Especially for gas rings.
