I fell for it. I purchased several of these for both 5.56 and 6.5CM. Every bolt I installed these on fails the "stand up test". After installing these, I pull the bolt all the way out and place the BCG upright on a table and... it collapses meaning they are not creating a tight enough seal. They do not seal like the OEM rings I was replacing. I'm not falling for it again.
Cons:
- They do not create a proper bolt chamber seal
Would recommend: No

Rings are easy to install and an extra is a must for a replacement parts kit. Will be buying again when time calls for it.

I bough to replace the gas rings on Bear Creek Arsenal bolt. The gun would bit cycle with due to low gas pressure. When I measured the ourside diameter withba caliper the JP one pices ring measured. 03" less than the 3 pices set. I would not recommend these except for a JP Enterprises Bolt and Bolt Carrier Group.
Would recommend: No

I have these for the AR15 and AR10 platforms, and they work very well. They are easy enough to install and very well made. I highly recommend

I had a 6.5 Grendel BCA upper BCG fail the stand-up test. So I ordered these gas rings and changed them out. Stand-up test past and my cycling issues are gone. These are well made, and was an easy install. I highly recommend!

Haven’t shot it yet, but amazed how much less friction these rings have over mil-spec.
This is an improved McFarland-Style one piece spiral ring. The precision edge grind actually makes for more surface area contact with the bolt bore, compared to both traditional 3 piece rings and the standard McFarland rings.
With Geissele enhanced BCG and this gas ring, the bolt will fully lock into battery under buffer spring pressure only if you slowly ride the bolt home with the charging handle. Butter smooth.
I only run one piece gas rings in my AR-15 and AR-10T.

I bought 2 of them for my Springfield Saint Victor and DDm4v7, both fit really well and made the guns cycled smoother specially when they ran dirty after couple hundred rounds. With my regular gas rings, when the gun were dirty it was hard to charge, but with the JP Rings, they had no problem charging (even when dry).
Pros:
- Made the gun charged smoother especially when dirty.
- Fit all my ARs
Would recommend: Yes

JP Enterprises single piece gas ring is premium as with all JP products I own. Not black as shown, though, which is why I bought exclusively from OpticsPlanet. Installation is a tad bit more challenging as well.
