The JP Enterprises Silent Captured Buffer Spring System For AR-10/LR-308 includes a spacer to allow for installation in both carbine-length and rifle-length buffer tubes. These AR15 Lower Parts from the experts at JP Enterprises are designed for use 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 the JPSCS-AR10 will function normally when installed with the supplied spacer. However, Armalite's .308 carbines use a slightly longer, nonstandard carbine extension tube. The JPSCS-AR10 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 JPSCS-AR10 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. For a sturdy and high-quality option in silent captured springs for AR-10 type rifles, choose the JP Enterprises Silent Captured Buffer Spring System.
