KNS Precision brings yet another great upgrade to the AR platform with the AR/MCX stock adapter. This lightweight adapter features an incredibly simple design to replace standard AR-style buffer tubes with a flexible M1913 picatinny rail. This adapter is not compatible with standard direct impingement AR-pattern rifles or rifles that require the buffer tube to contain the recoil system.
Compatible with AR-pattern lower receivers
Flanged model retains takedown pin detent and spring
Replaces buffer tube with Picatinny style stock mount
Low parts count for simplicity and strength
