- Gen2 features : aluminum shaft and added weight to the buffer
- Captured recoil spring and buffer system
- Tungsten weights instead of steel for added mass (2 tungsten, 1 steel)
- Gets rid of loud buffer spring noise and helps reduce bolt bounce
**This is the HEAVY buffer with tungsten weights. The increased mass helps to delay bolt-open, control the extra velocity of suppressed use and manage recoil for the hotter rounds available on the AR15 platform.
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.
JP's pursuit of perfection didn’t stop with springs and led ultimately to the creation of the Silent Captured Springs. Maintaining all the benefits of their polished buffer springs and proprietary 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 variant, regardless of rifle caliber.
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. Some out of spec tubes may require cutting the white spacer that is supplied for the best fit, but this is very uncommon.
*For the AR-15 standard weight version, please see the JPSCS-15
*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.
