Upgrade your AR-15's standard plastic handguard effortlessly with NcSTAR's aluminum M-LOK handguard drop-in rail system. Specifically designed for carbine-length rifles with a standard barrel nut, delta ring and handguard cap, this rail system seamlessly fits around the front sight post, providing additional length without requiring the removal of the gas block or A2 front sight post. The extended 13 inches length of the handguard offers ample space for mounting your preferred accessories, ensuring versatility and customization options. Installation is straightforward, simply remove the original handguard, place the M-LOK handguard between the delta ring and handguard cap and securely fasten it using the included screws. The package includes two M-LOK to picatinny rail sections, expanding your accessory mounting capabilities even further.
