The “spoon over a cheese grater” sound emitted by modern sporting rifles whenever they’re charged or fired has always been one of the AR platform’s ugly blemishes and one we’ve worked ardently to eliminate. After years of specially selecting buffer tube manufacturers based on the quality of their tubes’ interior finish, we opted to design and produce our own action springs with a perfect centerless-ground and precision-polished outside diameter. These JP Custom Buffer Springs are an inexpensive way to see exactly why we have a reputation for having the quietest, smoothest rifles on the market.

Our pursuit of perfection didn’t stop with springs though and led ultimately to the creation of the JPSCS Silent Captured Spring (patented) in 2012. Maintaining all the benefits of our polished buffer springs and proprietary LMOS buffer, this combination buffer-spring assembly eliminates the friction of standard buffer components resulting in outstanding smoothness and sound abatement. What’s more, the spring is removable from the assembly for custom tuning, and both the AR-15 and AR-10 versions of the JP Silent Captured Springs are functional in rifle- and carbine-length operating systems. The AR-15 version fits and functions in any gas-operated AR-15 variant, regardless of caliber and the AR-10 version should fit and function in any large-frame AR-10-type platform. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid (weighted) carrier.

Includes spacer to allow for installation in both carbine-length and rifle-length buffer tubes.

The JPSCS-AR15 will not function with Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling

These are known for causing short stroking aka failure to feed (bolt not traveling back far enough)
Unless combined with an adjustable gas block this buffer spring is unreliable in some rifles, just an FYI
Not hating on the product at all !
Just saying that its design is part of a low recoil management system and ideally used in conjunction with an adjustable gas block

100% correct IMO, great product, but even with the various spring weights it still needs to have an adjustable gas block. This is from personal experience BTW as I run it in my system (with the JP Adjustable gas block now).
