The Ergo Grips Superlite Modular M-Lok Rail System (1pc) 1.35" Int Dia Tube 12" Length is a lightweight, free float handguard designed to give AR-15 and M4 builders a slim, ventilated profile with plenty of mounting real estate. Machined from 6061-T6 aluminum and finished in a durable black anodize, this one-piece rail combines a 1.8" outside diameter with a suppressor-friendly 1.35" inner diameter, full-length Picatinny top rail, and M-Lok slots at the 3, 6, and 9 o’clock positions.

This 12" model is ideal for modern rifle builds that prioritize balance and control while still offering generous space for lights, lasers, grips, and other accessories. The free float design helps maintain barrel accuracy, while the included mounting hardware and simple installation make it a practical upgrade for range use, training, or general-purpose rifles. Ergo Grips’ attention to detail and proven track record in AR accessories are evident in the clean machining, secure lockup, and user-focused ergonomics of this rail system.
