PA takes care of their customers.

PA takes care of their customers. When this and my buffer "arrived" I found a damaged box with nothing in it. Contacted PA the next day and a new spring was sent out the same day. That said upon inspection the spring looks like a normal mil-spec spring. Once I get some testing done I'll update this review. Thanks again PA!!!

Works well as advertised. However, you could achieve the same effect just by lightly oiling or greasing a milspec spring. When comparing the JP spring to an oiled milspec spring, I found that there was no difference in feel or noise.
<br>The main issue with this spring is that it is not made out of stainless steel, unlike a milspec spring. After shooting about 200 rounds (non-corrosive ammo) and letting the gun sit for a few days, I discovered that the spring started to get some corrosion on it.
<br>I can't trust a spring if it's going to start rusting that easily so in the trash it goes.
<br>Save yourself some money and just oil you standard spring and it'll work just as well.
A must have in all my builds....

To put it simply, these springs find their way into all my builds. They smooth the recoil action and reduce the spring sound tremendously. Never had a cycling issue in any rifle with these springs.

This JP Enterprises spring, in lieu of a Sprinco "White" spring, actually made a discernible difference in a 6.5 Grendel 11.5" SBR equipped with a 3 ounce carbine buffer and a SLR Rifleworks adjustable gas block. Smoother cycling, less perceived recoil and quicker follow-up shots. Pleasantly surprised.

Ran 100 rounds through my new upper today with this spring much quieter “twang” than my other mil-spec spring going to buy another for that rifle.
Nice and Quiet

Does what it's supposed to and it's quiet (I put white lithium grease on it)...I like it!
Great Upgraded Spring
by Billy -
Had a problem with ejection on my ar. Got this along with a Spikes H2 buffer and all those problems went away. The action seems smoother. This spring is definitely an upgrade from my milspec spring that came with the buffer kit. This does nothing for felt recoil, but at least the spent brass is flying out of my ar as fast as I can pull the trigger.
Solid affordable upgrade

Wow. Fixed all my problems with cycling, misfires, jams, and doublefeeds that I was having using the cheaper target ammo (Tulammo). Put em in all 3 of my AR's. Guns just feel better all around. No slop. Ill never use stock springs again.
Above the rest

All AR springs are not the same. This spring is quieter and smoother than mil spec, but paired with a T2 buffer and Nitride or Boron BCG and it's as smooth as silk. These go into every build I do and well worth a few extra bucks
Best naked buffer spring on the market
by Kase -
I experimented with a variety of flatwire and chrome silicon springs in my AR's and have decided to replace them all with JP springs. Both the Tubbs and Strike Industries flatwire springs generate a lot of drag and resistance in the buffer tube--not smooth at all. That translates to a loss of energy and added wear to the buffer tube and the spring itself. There's also an aesthetic dimension that's being corrupted by the lack of smooth operation as well. Standard chrome silicon springs are better in that regard, but not even close to being as smooth and quiet as the JP spring.
Silky Smooth And Quiet.

Excellent product!<br><br>Replaced my stock carbine spring with a Strike Flat Wire and found it noisy with much drag on the tube.<br><br>Installed this and the charging cycle is smooth as glass and very, very quiet.<br><br>5 Stars to JP and, as usual, 5 Stars to Primary Arms.
The Best Spring for you Buck
by JBar -
Where do I begin? I had a mil-spec buffer and spring to start with. The recoil with mil-spec buffer and spring would knock you off target quick. The old spring had a metal rubbing sound when charging the rifle and every shot would hear a twang you could feel through the whole rifle. With this spring in those sounds and vibrations were gone. The bolt was setting better and took my misfires completly away with the TulAmmo. I love it, the recoil is nill and stays on target 10 times better now. I would highly recommend this.
My Go-To Spring

Excellent product; this is a must-have to tune your weapon to be absolutely reliable. These are in all of my rifles.

Awesome upgrade. less noise is far more pleasing than you would think.
High quality spring that definitely cuts down on the twang noise
Quality part, great service!
Extremely happy with the quality and price of this spring, would highly recommend to anyone doing a custom build.Delighted with the price and excellent service I always receive from PA.
Great quality buffer spring.
Works well in my carbine. This thing is quiet and recoil is practically undetectable. The gun cycles flawlessly, just like it's supposed to. Great price and performance for this critical part!
