JP Enterprises Gen 2 AR-10 H2 Silent Captured Spring

The JP Enterprises Gen 2 AR-10 H2 Silent Captured Spring is designed to work in standard-length M4/M16-style buffer tubes on AR-10-type rifles and carbines. Ideal for use with suppressed carbines, SBRs, and select-fire weapons, this captured spring eliminates the loud, annoying "rattle" noise of the standard M4 buffer spring and features a centerless-ground spring and precision polished outside diameter for ultra-smooth operation and reduced wear. The heavy H2 buffer reduces bolt bounce for a more enjoyable shooting experience. Plus, the single-piece design offers quick installation and removal for cleaning, maintenance, and custom tuning. Includes a spacer for installation in carbine and rifle-length buffer tubes. Not compatible with HK MR762, Sig Sauer 716, or Rock River Arms LAR-8 rifles, or the Daniel Defense DD5 bolt carrier due to a lack of clearance for the guide rod. Order today! Note: Because the insertion and removal of the Silent Captured Spring is very difficult with a standard buffer retainer pin, JP Enterprises recommends removing it when installing your SCS. This leaves the SCS "free-floating" in the buffer tube. The JPSCS2-10H2 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.
