JP Silent Captured Spring for AR-15 - Gen 2
The JP Enterprises GEN 2 Silent Captured Spring eliminates the loud noise of the standard M4 buffer spring and is designed with a perfect centerless-ground spring and precision polished outside diameter. This allows your BCG (bolt carrier group) to reciprocate inside the buffer tube faster, smoother, and more reliably. The single piece design makes it easy to remove from the buffer tube for cleaning, maintenance, and custom tuning. The weight of the buffer can be increased or decreased to match the needs of your rifle depending on the type of ammo being used or if a suppressor is being used. The silent capture spring also includes a spacer to make it compatible with both carbine and rifle length buffer tubes.
- Aluminum guide rods to reduce weight
- Included spacer for carbine and rifle buffer tubes
- Compatible with all gas operated AR15's
- Heavier buffer to reduce bolt bounce
- Smooth, friction-less operating system
- Silent operation
- 6.2 Oz
The JP Enterprises GEN 2 Silent Captured Spring is the perfect solution for reducing the noise and friction of your buffer system and is highly tune-able to ensure 100% function no matter how you have your rifle set up. Combine it with the JP Enterprises Variable Mass Operating System and you have a rifle that can be tuned to your specific needs whether it be for competition or for plinking on the weekends.
Equipment should not be a limiting factor. Whether a professional or a first-time shooter, move up to the best. JP Enterprises creates innovative new ideas that fill the needs of serious and recreational shooters. Their policy is simple: if you are not happy, they are not happy. These Custom Buffer Springs are a good investment to see exactly why JP Enterprises has a reputation for the quietest, smoothest rifles on the market.

Worth every penny
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.
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.

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.

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.
