JP Enterprises Enhanced One-Piece Gas Ring - .223

The main purpose of this gas ring is to reduce friction. You need to start with an overgassed system before using this, otherwise you risk it not functioning at all.

Efficiency is not the goal here, its friction reduction!
Its specifically made for rifles with low reciprocating mass and low spring rates so that a weaker buffer spring can still load a round and chamber it.

By design it is stouter than regular gas rings, but it is not intended to be used on gas systems who have a small gas port or with low pressure rounds such as 300blk.

Start off with an overgassed barrel such as faxon if you wish to use this, then use an adjustable gas block to reduce the gas until desired function is achieved.

If you wish to understand it better, there is a youtube video that compares the standard gas ring to these 1 piece gas rings and where and when to use them

I like to use these as replacement rings anytime I have wore out rings, or if I have issues with cycling sometimes. They don’t have to be as tight as normal rings, because there is no gap to close in. They have less tension which creates less drag and actually helps with cycling issues sometimes. I recently solved one case where the carrier was slightly out of spec creating too much drag on the bolt rings and was actually creating a short stroking problem. These JP rings solved the issue. Just remember that the normal wear test that you use for normal rings to where you stand the carrier up on the bolt and it should stay up doesn’t work with these. Because of the decreased friction, the carrier will slide down over the bolt under its own weight.

I bought this thinking it would be the top of the line gas ring, and I should have just saved my money. Shot 90 rounds with it and it was already failing the gas ring test in my nitride BGC. It was super loose and there was carbon buildup already forming on my bolt, on the other side of the ring. So obviously it was letting gas get by. I also noticed when I installed it (following the instructions to a T) that there was super thin shards of metal in between the ring coils that were flaking off. Not sure if this contributed to not having any luck with this ring. Switch back to the old school 3 rings and gun functions perfectly.

I was having trouble with gas rings caking with carbon after a few shots, after using these one piece rings, problem solved!

This works as advertised. Easy to install and you do not have to worry about alignment of the rings.

Absolutely fantastic, this worked 100% with my colt BCG that I use for re-enactments and rentals for full auto purposes. I plan to switch all of mine to these

I have this on 3 ARs and it works perfectly, so I ordered one for a 10.5" 5.56 AR Pistol build. Installation (before I ever fired a shot with my new AR pistol) was easy, but I noted that the bolt would not hold the bolt carrier up when placed on the bolt face (indicating that the rings were undersized), but I didn't think too much of it, and I was off the range for the very first time. I ran:
1) M855 green: zero issues.
2) Silver Bear 62gr HP: FTE or FTF every other round. Never locked back on an empty mag.
3) Silver Bear 62gr SP: constant failure to extract (three required me to "mortar" the weapon to get the ammo to extract), in addition to FTF.
I returned home, cleaned the weapon, uninstalled the one-piece gas ring, and reinstalled the original three-piece gas rings. I went back to the range and fired PMC 55gr Brass, Silver Bear 62gr HP, and Silver Bear 62gr SP. All ammo ran flawlessly. Zero problems.
In conclusion: the problem was the out-of-spec JP gas ring.

Couple weeks ago I was out shooting a .300 Whisper and it started to slow down. Get home and clean it only to see my gas rings were so worn that one broke and one bent. Since this was for a .300-221 pistol that had always had issues cycling some loads, I figured it might be time to try one of the fancy rings, but was concerned about friction with the lower pressure and impulse of the .300 Blackout. But upon finding out that JP makes such a product as they do here, I thought that might be the solution. And, after installing it and running through a few loads, it seems to work better than the regular rings did, keeps things a little cleaner, and cycles loads that weren't quite reliable with standard rings.

And yes, it's surface ground for a closer fit, so not enough friction to pass the supposed test of holding up the carrier, that's notated in the directions, even. But since it's a different thing altogether, it doesn't need to have a tight fit to seal, so that test's no good.

Good service with Primary but terrible shipping through USPS.

My fumbling around with the 3 piece rings is done. This 1 piece ring is the best I've seen. and super easy to install.
