in this video i share my experiences with the 1 piece and 3 piece gas rings for the AR platform. they both have their pros and cons. there is a place and time to use either, but it all depends on your needs.

The only rings I've ever seen not turn is oil wiper rings, everytime I've taken a motor apart i assembled the combustion rings are moved but the oil rings are not. You're one of the only people that truly understands gas rings! I've seen so many videos of people regurgitating the same information, your the only person to use your own terms. You have a good understanding of physics an also are good at communicating, very informative video!

Thank you! I do try my best! I am an automotive test technician by trade, alot of what i talk about in my videos is based on my experience from my line of work. I do take pride in what i do for a living and i love sharing these similar concepts with others who share the same mindset.

Took roughly 200 rounds to get the rings broken in an sealed actually ended up with more gas an less drag! It's crazy with how the bolt just falls into the carrier but yet can be sealed better. 100% think it's necessary if the ring path is in good condition, preferably a low round count carrier. When I took the bolt out of the carrier the half of the bolt towards the firing pin side had NO carbon beat the rings had sealed it so good before there would be carbon/ unburnt powdered in every crevice.

Thanks for sharing. Is it fair to say that you are under the impression the primary reliability issue you have run into with low mass carriers is not overcoming all the forces necessary to completely chamber the round? I've run multiple 6oz carriers with the springco yellow and have had the occasional malfunction, but when inspecting it with a high speed camera (and while not being able to reproduce a malfunction), it seemed more likely that issues in my case could have to do with bolt bounce more than falling to completely chamber. On one hand I could imagine a scenario where the one piece ring allow more bolt bounce as the friction is reduced but after it has bounced it would likely have a better chance of going fully into battery. Are you/would you exclusively run the jp one piece ring for a comp gun with an in spec low mass carrier?

This was helpful. My new 308 build … BCG is refusing to open. Gas port fully open …. It’s basically a bolt action. And every time I use the charging handle i have to brace it and use both hands. I checked headspace. No issue. Saw this video. Took out gas rings. It’s smooth as butter. So I’m gonna try the JP gas ring. Ordering it. Thanks for the explanation.

Your problem is that whoever made your barrel or gas block didn't drill the gas port to spec, or it's plugged. not a gas ring problem.

@@smokecrackhailsatan right. Gas port too small. Typical on these barrels from BCA. But changing gas rings easier than drilling hole. But yes. It’s the hole poorly made

As they wear out, it allows the opening in the rings to open up. If the opening in the rings have aligned, more gas and debris will escape. Only a big deal in extreme wear cases.

Great explanation! Thank you for that because I always wondered, I run Sprinco gas rings and all my springs but Ill order a couple one piece and give em a try. Now I know what to look for or expect….. I use Sprinco blues in all mine and the forward pressure is on point lol I think it would work fine if my tolerances work.
@eitrisenhancementsllc Жыл бұрын
Glad to help! I also stick to sprinco, or at least a reputable company like geissele, JP, and others. Is there a particular reason you are seeking to replace them? You are welcome to try them, but unless you are having problems of either weak forward pressure or short gas ring life, i would just tell you to save your money. They are good, but their uses are for such niche applications that the extra cost isnt worth the gains unless you are actually having a problem. If you are planning to get one simply as an upgrade because you like it, then more power to ya. They will outlast standard gas rings. Although i would pay the extra for the JP surface ground ones. Hope this helps!

I always thought the gas rings are spring loaded so they form a tight seal against the bore of the carrier’s bore with making it an interference fit. If they’re not tight that means gas and the debris the gas is carrying will blow past the the rings and out the back of the bolt into your fire control group. You don’t want that flowing past the gas rings, that’s what the vents in the side of the carrier is for, that blow the excess gas out of the ejection port.
@eitrisenhancementsllc4 ай бұрын
They are mainly spring loaded to take the shape of the bore. Having the shape of the bore is what provides their seal, not so much the pressure against it. Any gas that makes it past the rings simply makes it to the vents on the bcg. However, the Carbon on the fire control group is more than likely coming from the bolt tail seal. The bolt tail doesn’t use gas rings so there is always a leak there. The vents are simply there to relieve the pressure once the bolt has been unlocked that way it can redirect excess gas away once the needed amount has been used.

Honestly, I was looking at JP to extend the life of my rifle. The firing pin and gas rings have been my issue and I forgot I had a JP bolt on my 22” Grendel that’s had 0 issues for awhile. I’ve always replaced with regular gas rings. My goal for my 5.56 is to remove as many of the failure points as possible while maintaining or increasing reliability. So far I’ve been replacing my bolt head and buffer but normally at 6k/7k I’ll have to replace the gas rings, which is annoying, because at 12k I have to replace the bolt and barrel anyways normally. Im gunna try this out with my 6.5k gas ring swap rn and if it works to 12k I’ll swap it over to the new bolt.
@eitrisenhancementsllc Жыл бұрын
This makes sense, and honestly it should be able to make it to 12k considering the jp gas ring will not be dragging as aggressively as the standard gas rings. As long as you are fitting the jp gas ring in a bolt carrier that has good tolerance control, i expect zero issues. Honestly, JP’s surface grind is what the one piece gas ring needed to be perfect in operation. Only thing where it still suffers is if the bore that its going in is properly spec’d or not. If using a high quality bolt carrier, then i have no doubts the jp gas ring will just shine and eliminate wear almost entirely.

@eitrisenhancementsllc Жыл бұрын
Id recommend against this, you will actually lose efficiency, the JP gas ring should only be used on platforms that have excess gas available. If lack of gas is the issue then i highly suggest you keep the 3 piece gas rings If you are struggling with cycling, i recommend you go another route that i just experimented with with excellent results. Change the hammer spring to a reduced power hammer spring. Currently im using a geissele ssa-e with an alg purple hammer spring. This has no effect on pull weight on a 2 stage trigger, and since the geissele hammer is lighter, there is no need to “bob the hammer” People forget that it takes energy to cock the hammer. Not only that, its energy stolen from the cycling of the bolt. Reduce energy required to cock hammer, more of that energy gets used to cycle the bolt. The results were quite drastic for me, especially since its energy stolen at the beginning which is the most important time for guns with short dwell time.

I stand corrected, my testing has shown the opposite, ive had great success with jp gas rings in 300blk Just have to make sure you are using a properly spec’d carrier. Typically anything chrome lined will be g2g

The 300 Bo was designed for a 200 gr. bullet using a silencer. Which gives the back pressure. Without a can an AR15 will operate well with bullets from 115 up to 135 maybe a little more.

I only have one DGI gun, a 300BLK with a Lantac BCG & bolt. I've been using McFarland rings on it since it was new (about 6 years) and I have never had any issues whether sub-sonic or super-sonic ammo is used. The rings do get pretty grungy, but it doesn't seem to have any effect on operation. I suspect that any excess buildup of carbon at the rings just gets blown away by gas pressure during firing. Whether it was 30 rounds fired or 300 rounds fired, the amount of carbon at the rings won't indicate how many rounds fired. It's about the same either way. This video was VERY painful to watch. Maybe making some notes before hand to have a better flow of information would help. Or maybe not.
