NBS Free Float M-LOK Handguard

The NBS Free Float M-LOK Handguard is a no-nonsense American made M-LOK compatible rail system designed for versatility and simplicity. It features a monolithic top picatinny rail and the remaining 7 sides all feature M-LOK attachment slots. Precision machined from 6061-T6 aluminum extrusions then type 3 hard coat anodized, you can be sure that this handguard will withstand an incredible amount of abuse. Its slim profile feels great in the hand yet with a 1.35″ inside diameter it can accommodate any true low profile gas block and has enough clearance to recess some muzzle devices such as flash cans and linear compensators. It is a true do-anything rail system and the cost-value ratio makes it very hard to pass up.
