• .250 takedown / pivot pin holes
• No forward assist
• Weight: 7.1oz

* Please note this upper only comes in black. If you are interested in having it cerakoted to match the handguard, please contact us for information on our cerakote services!

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.
