Armaspec Self-Retention Castle Nut Flat Dark Earth AR-15/M4

Armaspec Self-Retention Castle Nut Features The Armaspec Self-Retention Castle Nut uses a patented thread locking design that locks the nut in place on the buffer tube without requiring staking or chemical thread locker. That design saves real time during a build since the installer skips the extra step of applying and curing thread locker or deforming the receiver with a staking punch. Machined from 7075 aluminum rather than standard mil spec steel the nut is both lighter and stronger than typical castle nuts found on factory rifles. The self retaining threads also make future disassembly easier since there is no staked metal to clean up before the nut can be removed. Finished in Flat Dark Earth anodizing the castle nut adds a coordinated color accent to builds using FDE furniture while providing the same corrosion resistance anodizing is known for. It is compatible with standard AR-15 and M4 buffer tube threads making it a drop in upgrade for most mil spec and commercial spec builds. Because it is made from premium grade aluminum the nut helps shave a small amount of weight from the rear of the rifle. This castle nut is a simple effective upgrade for any AR-15 or M4 build looking for improved reliability and finish.
