Built for those who value performance and precision, the R-ONE handguard is machined from 6061-T6 aluminum to offer a lightweight, rigid solution for your AR-15 build. Its standout feature is the Aero taper lock Attachment system - a sleek, reliable interface that uses dual tapered locking nuts, a custom barrel nut and a turnbuckle screw to apply balanced clamping force, all locked-in place with a ratcheting detent for a secure, repeatable install. The system not only looks good but prevents the kind of handguard distortion often seen with other setups. Designed for perfect compatibility with the Aero M4E1 threaded Upper and most mil-spec receivers, the R-ONE also comes complete with all the hardware you need - though it may not fit billet uppers due to indexing differences.

Compatible with low-profile gas blocks
