• Slim profile for comfortable hand positioning: reduced outside diameter for natural hold

• Full-length Picatinny top rail for optics and backup sights

• M-LOK slots on multiple faces for modular accessory mounting

• Superior heat dissipation thanks to air-gap free-float mounting and open-slot design

• Easy installation with standard barrel nut interface (verify compatibility)

• Available lengths: 7″, 9″, 12″, 15″ to match carbine, mid, and rifle gas systems

• Fully deburred edges and ergonomic machining for snag-free use

Frequently Asked Questions

Will this handguard fit my AR-15/M16?
It fits most AR-platform uppers that use a standard barrel nut interface; verify receiver type and gas system length (carbine, mid, rifle) before ordering.

What is the advantage of a free-float handguard?
A free-float handguard does not contact the barrel, reducing external influences on barrel harmonics and often improving shot-to-shot consistency.

Is this handguard compatible with M-LOK accessories?
Yes — the handguard includes M-LOK slots on multiple faces for direct-attach M-LOK accessories.

Do I need special tools to install it?
Basic armorer tools (armorer’s wrench, torque wrench) are recommended. Professional installation is advised if you’re unsure.

How do I choose the right length?
Select a length that clears your gas system and desired gas block (carbine/mid/rifle) while giving the accessory real estate you need.
