- Standard weight buffer assembly
- Sold as a partially assembled SCS unit
- Suggested for any 14.5-20 in. non-suppressed AR-10 platform
The JP Gen. 2 Standard Silent Captured Spring Builders Kit is a great option for anyone that does not plan to shoot suppressed. The standard builders kit works best with carbines that have barrels that are 14.5" or longer. This builders kit will include a total of 3 alternative springs making your options with this spring greater.
Note from JP on compatibility : The JPSCS2-10 is designed to work in standard 7-inch M16/M4-length buffer extension tubes on .308 AR-type rifles like the DPMS LR-308. 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, non-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-inch .223 carbine extension tube.
The JPSCS2-10 is not compatible with the HK MR762, the Sig Sauer 716, or the Rock River Arms LAR-8 because of its longer bolt stroke and subsequently longer extension tube.
