Dead Foot Arms Modified Cycle System Right Side Folding Stock Adapter – 9mm



Dead Foot Arms Modified Cycle System

The Dead Foot Arms Right Side Folding Stock Adaptor for 9mm ARs features a modified cycle system using a proprietary bolt carrier group/buffer combination. Used in tandem, this adapter/buffer/BCG configuration allows an AR-9 to cycle with the folding stock in the open or closed position.

YOU CAN USE ANY COMMERCIAL OR MILSPEC BUTTSTOCK OR PISTOL BRACE WITH OUR SYSTEM– and thus we provide this as an optional separate purchase, as many AR owners enjoy the stock they currently use.

Right Folding Stock – Opens at an angle to avoid forward assist and ejection port

Left Folding Stock – Opens in parallel with the barrel

NOTE: Compatible with any commercial or MIL-SPEC buttstock.
