Attach most M16/M4 style braces or stocks to your favorite AKM/AK74 rifle, including the KR-103. JMAC's M4-AKM Stock/Brace adapter is very unique in the way it mounts to the rifle! JMAC's completely replaces the factory T-Nut with JMAC's proprietary mount and is INCREDIBLY STRONG! Because it replaces the T-Nut you dont need any special adapters for the various fixed stock trunnions, if its a square back receiver and has an AKM/AK-74 style rear trunnion its very likely to fit! Why buy JMAC's? Its incredibly strong, machined from 7075 and hardcoat anodized, offers an optimal cheek wield for irons and red dots, has built in QD sling points 7075 Alu Mfg: Jmac Customs
