15″ Large ID M-LOK Handguard – 1.75” Inner Diameter | Suppressor-Ready AR-15 Rail
Build a clean, modern rifle with this 15″ large ID M-LOK handguard, engineered specifically for recessed suppressor and oversized muzzle device setups. Featuring an expanded 1.75″ inner diameter, this rail provides the clearance needed to partially tuck most suppressors inside the handguard—giving your build a streamlined, integrated look with a recessed suppressor.
Designed for both form and function, this free float AR-15 handguard offers a rigid mounting platform with M-LOK compatibility, a continuous Picatinny top rail, and anti-rotation tabs to ensure a solid, repeatable fit.
Despite its larger internal clearance, the handguard maintains a comfortable external profile, making it ideal for extended shooting sessions without sacrificing control.

sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
