The ambidextrous CMMG RipStock is a minimalistic buttstock assembly for AR-pattern rifles. The proprietary system—which incorporates the rifle’s buttstock, receiver extension, buffer, action spring, castle nut and receiver end plate—is adjustable to five length settings by simply pulling straight back on the stock. Repositioning an index screw located on the buffer tube also allows the user to preset a personal maximum length setting, allowing the unit to be quickly deployed at the shooter’s preferred length of pull. Check with CMMG to ensure compatibility with specific cartridge configurations. MSRP: $200. cmmginc.com.
