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
by Phil -
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.

This spring is nice and quiet and helps reduce felt recoil. I highly recommend it as it preformed as discribed. I have all JP Enterprises springs in my AR and it makes a huge difference.Shipping is also extremely fast, Primary Arms has a customer for life.
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!
The one I got was not silent. Though significantly quieter than a stock spring. What was really interesting was its effect on recoil impulse. My 6.5 Grendel now has significantly reduced recoil and it didn't exactly kick like a mule to begin with. With an oddly different impulse, it feels like a two stage kick if that can be imagined.
JP Tuned and Polished
Very high quality make if you willing to pay an extra.
As advertised, if you want to get rid of that rasping noise this spring is the way to go!
Great quality piece.
What can I say, it's JP quality all the way.
JP Tuned and Polished Extra Power AR-15 Carbine Bu

I am happy with my purchase.
by Robert Jaquith
The JP buffer spring is a great upgrade for your rifle. It comes with instructions and additional information about the spring. I purchased one of these when I swapped the full size A2 stock for a collapsible one. I highly recommend this product to anyone who enjoys shooting the AR-15. My order shipped the next day.
Just as described. Worked great for my build and fast shipping.
Superior quality at a great price!
by Greg Dennis
This spring is so quiet. I have a 7.62x39 and it really helps with the increased recoil and functioning of my AR platform. Would highly recommend it.
by Jacob McDowell
Spring does as advertised, added this and a H buffer to my rifle because of an over gassing issue and it solved the problem. This spring is of higher quality and strength than the spring that came with my rifle. Also helps with that annoying noise.
