Note: The JPSCS2-15 will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.
The JP Enterprises Gen 2 Silent Captured Spring Standard Version is a premium upgrade for AR-15 buffer and spring systems, engineered to deliver ultra-smooth cycling and eliminate the gritty “cheese grater” sound typical of standard buffer components. Designed for gas-operated AR-15 rifles, this all-in-one buffer and spring assembly incorporates JP’s patented Silent Captured Spring technology, offering a refined shooting experience through reduced friction, minimal vibration, and unmatched quietness. At just 5.3 oz. total weight with a 2.9 oz. reciprocating mass, it’s ideal for replacing a standard buffer of the same weight and comes with a spacer for compatibility with both carbine- and rifle-length buffer tubes. Whether you're optimizing for competition, defense, or range use, this silent buffer system enhances feel, consistency, and performance in every shot.

JP AR-15 Silent Captured Spring Gen 2: Next-Day Delivery, Superior Packaging, and Enhanced Shooting Performance!
by Andres -
The JP AR-15 Silent Captured Spring Gen 2 exceeded my expectations. Not only did it arrive the next day, but it was also packaged exceptionally well. The installation was straightforward, and the reduction in noise and recoil is impressive. Its top-notch build quality ensures long-term durability, making it a must-have upgrade for AR-15 owners seeking enhanced shooting performance.
Way better than the standard buffer

I have 3 of these in my AR’s. They are a great add and quiet down the spring sound when operating. I will buy more as I need them. They are well worth the price. Comes with installation instructions, spring assembly, spacer and washer for rifle length buffers. You won’t be disappointed.
Very smooth

I just installed this in my 6mmARC used for PRS gas division. It’s shoots a whole lot smoother. Hard to explain, but the recoil impulse feels more like a bolt gun (which is a good thing!!) The “cheese grater” sound really never bothered my, as I shoot with ear pro. But the “slickness” of the recoil impulse is definitely better. I got the standard. I had no adjustments required in the adjustable gas block. My reloads, 105g running 2785fps, landed about 4 O’clock in a pile that could be cover with 2 open hands. Definitely recommend.
For a evolved and refined recoil sensation, Fantastic!

I put off buying one of these for longer than I should have. They are simply magical. I love the refined recoil impulse these provide. It is quitter sure, but it also does something even better which is to give your gun a evolved recoil feeling, especially if you mass regulate with buffer weights and low mass BCGs. Throw in an adjustable gas block you can have a super flat shooting absolute beast of a gun. I am running mine with a low mass carrier and a law folder with the anarchy hollow bolt extender and my MK18 is fast and flat battle axe. Seriously these things are awesome worth every single penny.
Very Nice!

Smooth like butter! I’m buying one for all my AR type rifles! Stop reading reviews and buy this now! You will not be disappointed!
Excellent product
by Tyler -
Worked perfect for my match 5.56 build. Eliminates the spring sound when shooting. I personally dont feel any difference in felt recoil though. Excellent service through Primary Arms as always.
Perfect add
by Stephen
Purchased and used one of these in my 458 I built. Absolutely the best piece of equipment you can upgrade. Normally you get that pogo stick sound of spring action each time you pull the trigger. This totally eliminated the kaa-choing sound a normal spring makes. Has worked 100% each time out.
Worth every penny
by Dylan
This is one of the best upgrades you can put into your AR platform. It feels so smooth while firing and takes out the hollow tube and spring noise completely. They are expensive, but worth every dollar. I am putting one in all my rifles, and they make one for the AR9 variants, which I will be picking up as well.
