JP Silent Captured Springs (AR-15 buffer assembly replacement). Strong-Side Tactical is an authorized Master Dealer with JP Enterprises.

**This is a drop-in unit that fits in any buffer tube including the VLTOR A5 buffer tube. The unit works in cabine, mid or rifle length AR-15 rifles. Fast, easy installation.

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 JP has worked ardently to eliminate.  After years of specially selecting buffer tube manufacturers based on the quality of their tubes’ interior finish, JP Enterprises opted to design and produce their 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.

JP's pursuit of perfection didn’t stop with springs and led ultimately to the creation of the JPSCS-15 Silent Captured Springs. Maintaining all the benefits of theirr 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 for AR-15 rifles. 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. *For AR-10 applications, please see the JPSCS-10. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid (weighted) carrier, The JPSCS will NOT work with (PWS) Primary Weapon Systems DGI bolt carriers.  The design of the carrier will prevent the rifle from cycling.

  2. Works as Described 5 Star Review

    Posted by on 2nd Feb 2015

    Just put a couple hundred rounds through my rifle and the annoying twang of the spring is gone. Very smooth. My buddy compared it to his with a spring and buffer and immediately wanted to know where to get one. Not inexpensive, but well worth it for me.

  3. Great for tuning your gas system 5 Star Review

    Posted by on 5th Jan 2015

    I biught this so I could tune my gas system better. I have an adjustable gas block and wanted more tunability than a standard buffer gives you. I also wanted to be able to use a carbine length system so my wife and daughter could use my gun too. I really don't notice the difference in sound much, but the standard sound of a buffer never bothered me. It does make a huge difference if you are going to suppress your rifle. With the rifle suppressed, and any sound stands out.
