Jp silent captured spring, worth it?

[Zeneffect]

I already don't have twang using a super 42 spring, but the system isn't terribly tunable in comparison.

Any opinions as if moving to a jp is really an upgrade? How is reliability of the jp part? I see a bunch more stuff that can fail on the silent captured spring setup vs a traditional buffer and spring setup.

I have them in all my ars and have had no issues.

The JP SCS does not increase nor decrease reliability in my experience, but there are others who claim the JP SCS is not as reliable as the standard buffer- spring and will never recommend them for a duty gun..I use JP SCS's on all of my hunting and competition AR rifles... The JP SCS does make charging the rifle much smoother and will improve recoil if you know how to set the gas port to the correct SCS recoil spring weight. No matter what Karl from DeRange claims, there is no need to worry about the mil spec recoil retaining detent breaking and jamming the rifle as long as the rifle is in spec. There should be a minimum of .030-.040 space between the buffer detent and the buffer when the rifle is closed..The buffer should never touch the buffer retaining detent until the upper is opened from the lower...

The sound a recoil spring makes is for me a non-issue. Especially when accompanied by a 160db muzzle blast.

Never had an issue with the stock MILSPEC springs.

I sort of like the loud spring. It's sort of an early warning system that let's you know when you're out of ammo.

I would save some money and go with the Armaspec Stealth spring. I have several of them and several JP's. I see no functional difference between the two.

I have 2 JP's in Grendels and 2 without - normal AR springs. Other than noise no difference in functionality. I won't "spring" for a JP again.

I have them in all my arm's.

I have one that has 50k rounds on it, I replaced the spring,spacers and bumper around the 28k area just because I felt it was time but I wasnt having any issues with it.

It does make the "sprong" noise go away and it does make the rifle fell like it's running on bearings it's so smooth.

With the spring kit and weight kit there is a ton of adjustments that can be made to it.

But it is part of a system, for the best results it needs too be paired with a low mass bcg and adjustable gas blocks.

Is it worth it? Well for me, yes it is. And all my freinds and family who have shot my guns, have put a scs in their guns soon after.

I take the buffer retainer out of my guns, simple because I dont feel like dealing with them, even before I went to the scs system, I didn't use the buffer retainer.

Long as you have a adjustable gas block you can basically drop the scs straight from the box into your gun and find a gas setting that will work. It's when you add the spring/weight kitsch and use a lowmass bcg that you truly see how well a ar can run.

The JP SCS is better for mitigating recoil than the traditional mil spec buffer IMO.. Adding tungsten weights to the buffer, slows the velocity of the bolt carrier group while increasing the weight being cycled. The purpose of tungsten weights was to slow the bolt carrier velocity so the magazine had time to replace the next cartridge being chambered..The M-4 carbine was cycling faster than the magazine could replace the next cartridge, resulting in malfunctions. The upper receiver feed ramps was the first solution to this problem.. The original steel weights were introduced to the system to prevent bolt bounce malfunctions after the military started using ball powder.. The more mass cycling, the more the recoil impulse.. Adjusting both ends of the recoil system is necessary, if maximum reduction of recoil impulse is the goal.. Reducing the gas allows reduction of the recoiling mass,"buffer weight- bolt carrier" which reduces recoil impulse..Finding the right balance has created a market all of it's own, with adjustable buffers, gas blocks, recoil springs, and bolt carriers..This can result in an operating system with the least amount recoil, running on the very edge of reliable function. I haven't mentioned what happens when throwing into the mix different pressured ammunition or suppressors... If faster split times or a smoother cycling system is desired, then it can be worth the cost. If max reliability is the goal, then probably not.. It all depends on the shooters goals and priorities..

A JP SCS is like rich creamery butter. Everything else is just margarine. From a functional standpoint, I do find that they make a difference keeping my sight picture on target when the bolt returns to battery, especially with less comfortable positional shooting. Part of that is proper tuning, but I find the return to battery is smoother.

Wow!

So much here.

Super simple solution to twang; use grease on your buffer spring.

I use the same grease I have for my Dillon press.

Schaeffer's 229 ultra red supreme.

I cover each coil, rotate 180 degrees and cover each coil.

Smooth and quiet.

As for recoil, use an adjustable gas block.

I can't remember ever mentioning the need to remove the spring twang during recoil for my reasoning for using the JP SCS LOL..I'm confused why JP SCS haters keep stating this as the reason people use it?? Re-read what I stated about the process of reducing felt recoil, smooth cycling and working from both sides of the gas system to mitigate recoil..You can add all the grease you would like to a standard spring and it will never cycle as smoothly as the JP SCS....

It's worth it to me, I won't run any of my AR's without a SCS. I personally can't stand a standard spring.
