JP Enterprises Gen2 AR10 Silent Captured Spring Builder with Alternative Spring Pack H2 Buffer Version MFG # JPSCS2-10K-H2
The "spoon over a cheese grater" sounde emitted by modern sporting rifles whenever they're charged or fired has always been one of the AR platform's ugly blemishes and one they've worked ardently to eliminate. After years of specially selecting buffer tube manufacturers based on teh quality of their tubes' interior finish, they 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 they have a reputation for having the quietest, smoothest rifles on the market.
Their pursuit of perfection didn't stop with springs though and led ultimately to the creation of the patented Silent Captured Spring in 2012. Maintaining all the benefits of their 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 AR15 and AR10 versions of the JP Silent Captured Springs are functional in rifle- and carbine-length operating systems. The AR15 version fits and functions in any gas-operated AR15 variant, regardless of caliber and the AR10 version should fit and function in any large-frame AR10-type platform. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid (weighted) carrier.
Gen2 SCS Improvements:
- New aluminum guide rod cuts overall weight.
- Heavier masses translate to more buffering mass and reduced chance of bolt bounce.
- Full correspondence between SCS masses and H1, H2 and H3 buffers.
- Additional mass added to both AR10 and 9mm models for better, broader function.
- Interchangeable buffers allwo conversion between AR15 and AR10 models
Includes partially assembled SCS unit, three alternative weight springs and spacer to allow for installation in both carbine-length and rifle-length buffer tubes.
Recommended Use:
- Short-Barreled Rifles (SBRs)
- Suppressed Weapons
- Rifles recommended to use an H2 buffer
- Select-Fire rifles
- Piston-operated rifles
Compatibility:
- The JPSCS2-10 is designed to work in standard 7" M16/M4 length buffer extension tubes on .308 AR type rifles like the DPMS LR308. Armalite .308 Rifles, likewise, use these standard M16 extension tubes with rifle-length stocks, so this unit will function normally when installed with the supplied spacer. However, Armalite's .308 carbines use a slightly longer, now-standard carbine extension tube. The JPSCS2-10 can still be used with these extension tubes by installing the spacer, which must be modified to fit. Alternately, the system will function readily if the longer Armalite carbine tube is replaced with a standard 7" .223 carbine extension tube.
- The JPSCS2-10 is not compatible with the HK MR762, the Sig Sauer 716, or the Rock River Arms LAR8 because of its longer bolt stroke and subsequently longer extension tube.
