JP Enterprises Silent Captured Buffer Spring

[sinlessorrow]

I don't have a clue about any of the engineering in the system or the buffet weights but I was told that this thing wasn't built just for competition. It's being run by working rifles too.

thanks for the input, I wish someone would do a comparison on auto to test RPM vs a standard carbine spring and H2 and also test for bolt bounce.

Has anyone used this JP silent spring on a gas-piston AR?

[Dave-HuldraArms]

I have three of them in 3 of my Huldra rifles with the Adams piston system. First, I won't go out and say that this is a "needed" item and I don't get into the noise thing. The initial reason we got some to test was because customers ask us is X Y Z compatible with your rifle type questions. With that we like to test as many X Y and Zs as we can and at a recent carbine course the JP SCRS came up. We have also tested the A5 system, different weight buffers, different springs brands materials etc.

The class was a Trident Concepts Combative Carbine course, about 2000 rounds in 3 days. I ran the spring in my 16 Tac Evo Elite, a 16" mid length piston gun. At first I noticed the difference in the "smoothness" and sound of just cycling the action the first few times to get a feel for the part. Now thats all fine and dandy but I wanted to see if it would run. As I started to run drills in Jeff's class I was actually really impressed by the system. It changed the recoil impulse to a smoother pulse and I found it was noticeable. Now I'm a big guy so I don't really get into the recoil difference of a DI vs Piston AR, to me they both feel similar and they don't push me around much.

What I first felt was a smooth recoil impulse and recoil management was easy. I was able to fire off controlled fire drills fast and efficiently with excellent accuracy and control. My groups were tight and times were fast. I started shooting more and more rounds in the drills to push the envelope, but the drills remained controllable and efficient. For me I noticed shot to shot times/splits seemed faster and there was less muzzle rise. Now this could be part of the hype effect but those who shot it after without knowing what was in there, commented on how smooth the gun felt and the reticle didn't really move. Some guys start to analyze the recoil both ways, as the buffer moves back and as it comes back, for me I don't get that scientific but it appeared the recoil impulse was yes smoother but also more "swift" and quicker to terminate if that at all makes sense. I know I am rambling but its kind of hard to describe. I was running a standard a2 so no comps or anything fancy, ammo was XM193 55 gr. Also my optic was a Trijicon TR24.

Overall I am actually impressed, it is a well built product, durable and rugged so far. Have about 3500 rounds through one rifle with one and just under 1000 rounds on another in my competition rifle. So far so good no stoppages or jams. Maintenance is easy, I run a little Slip grease on the rod sometimes EWL and it is nice and smooth.

The third spring is in a test gun, and 18" rifle length gas piston rifle. I also got some of the different rated springs to test with this system on this particular rifle. The other spring units have the standard spring. JP now has the other springs available so the system can be tuned to work with various gas systems.

So far I plan on running the first spring until 5000 rounds, inspecting, and then run another several thousand rounds and see what happens. I am planning on going to a couple carbine classes next year and that will be the rifle that I run. On my competition 3 gun rifle I plan on keeping it in their as well.

The downsides, yeah they weight a little more then the standard buffer and spring, actually a few ounces more. And of course the cost, at $125 a piece that can be an expensive upgrade from a quality buffer and spring. Is it worth it? I am still not sure if I will put one in every rifle I have, that'd be pretty expensive. But I like the ones I have to the point that they will probably be a fixture in my armory.

So forgive my ignorance but what is this for? what does is do that a regular system doesnt ? all ive gathered is that its expensive and quiet?

It's a lot smoother than a traditional buffer and spring. I equate it to cycling a Custom 1911 vs a Glock for example.
Smoother means it will cycle with less issues and that it needless gas to make it cycle. Less gas means less recoil. It's cream on top of the low mass system pie that JP already has perfected.

Do you need one? Absolutely not! Should you want one? Of course!

Great response to a totally legit question. I just ordered a Stag 3GL, now I hate you Jesse, yes i'll be buying one(JP Enterprises Silent Captured Buffer Spring) . BTW All my Glocks cycle better than either of the custom 1911s I shot and did so for many $$$ less so don't be going there. .

[Bulletdog]

Thanks for the info Jesse. I'll be looking further into this product. Sounds like it has some pretty positive attributes.

On one hand, if it ain't broke don't fix it. On the other hand we'd still be shooting the ARs of 1968 if people like John Paul didn't look for ways to make a good thing better.

Innovation can be a bumpy road. Some people are scared to travel it.

[The_Hammer_Man]

From a specialist/competition view point I think this product has a lot of merit.

Do I think it "fixes" anything? NO.

It's a specialized piece of equipment meant to be used in a particular way in a particular shooting environment. 3-gun.

There's an old adage that goes: "Smooth will always be faster than quick". Anything that smooths out the recoil impulse in a competition or precision rifle is "good thing" in my book. I'll be purchasing a couple of these to test in one of my SPR builds to see if it helps or hinders performance and reliability.

I believe this will end up being one of those pieces of gear that marginalizes your performance in a competitive environment like 3-gun. I think it's a similar situation we had in competition circles when 3-port muzzle brakes came onto the scene. If you didn't have one you couldn't "hang with the big dogs.

Please remember most open class 3-gun rifles are "one trick ponies" in that they are set up to be accurate with ONE particular ammunition load.... not everything in the ammo locker like a military weapon.

Do I think that this technology will eventually "trickle down" to the street cop and average weapons user anytime soon? Again, no. Do I think it has a place in the competition/precision rifle world? Hell YES!!

Howdy, I wanted to chime in with what I have going on.

I have been running this same JP silent spring buffer for 6 months in one of my AR's. In this rifle, about 1000 rounds since the install, and it seems to run a bit smoother than the standard spring.

The rifle is a PWS 16" piston upper with a Seekins lower, Chip trigger, mag pull furniture, and Leupold MK4 CMR 1.5 to 5 optic.

Now this past weekend I installed a HTG Eureka suppressor and right away I got two feeding issues. The rest of the mags worked fine, but no doubt it feels different with the suppressor. I know I increased back pressure some, so I will test it out more next week. I hope this part can handle the suppressor pressure increase.

Very interesting, so do we have a long-term review candidate yet?

[LMTRules]

Wish this thread could be revived. I'm waiting on my LMT LM8MWS SBR to get out of NFA jail. Planning on my Saker 762 getting put onto it. Want it to stay reliable, but tame the over gassed issues I keep reading about. That and a sexier recoil pulse would be nice, especially for the wife to shoot.

WTF is a "sexier recoil pulse"?
