Rise Armament RA-905 7.50" AR-15 Handguard - 6061-T6 Aluminum, Black Anodized, M-LOK, Picatinny Rail

The Rise Armament RA-905 is a 7.50" AR-15 handguard built for shooters who want a lightweight, modular platform without compromise. Machined from 6061-T6 billet aluminum and finished in hard-anodized flat black, this handguard tips the scales at just 9 oz., keeping your rifle trim and nimble whether you're running a patrol carbine, competition build, or precision setup. The full M-LOK slot design wraps 360 degrees around the tube, giving you genuine flexibility to mount lights, grips, and accessories exactly where you need them—plus a top Picatinny rail for optics or iron sight co-witnesses.

Rise engineered the RA-905 for free-floating barrel setups, so accuracy gains aren't left on the table. The anti-rotation, anti-slip design means your handguard stays put through recoil and hard use, while the included steel barrel nut and hardware make installation straightforward. The slip-on alignment system gets you mounted fast without guesswork. Every unit is precision CNC machined to aerospace-grade tolerances (AS9100)—a higher standard than typical firearms manufacturing—and finished to MIL-A-8625F Type III Class 2 specifications for durability that handles range days, training, and field work.

Made entirely in Broken Arrow, Oklahoma, the RA-905 comes backed by Rise Armament's 100% product guarantee and lifetime manufacturing warranty. If you're building or upgrading an AR and want a handguard that balances weight savings, modularity, and real-world durability, this one earns its place on serious rifles.

Specifications

Frequently Asked Questions

What AR-15 rifles is this handguard compatible with?

The RA-905 is designed as a drop-in M-LOK handguard for AR-15 platforms using standard barrel nuts. It works with both rifle and carbine-length gas systems. Confirm your barrel diameter and gas tube clearance before purchase, as fit may vary with non-standard uppers or specialty builds.

Can I use this handguard on a free-floating barrel?

Yes. The RA-905 is specifically engineered for free-floating barrel setups, which means the handguard does not touch the barrel. This design maximizes accuracy by eliminating barrel harmonics interference.

What comes in the box?

The handguard includes the aluminum tube, steel barrel nut, and all necessary mounting hardware. You will need a standard AR-15 upper receiver and barrel assembly to complete installation.

Why is this handguard made to aerospace standards?

Rise Armament manufactures the RA-905 to AS9100 aerospace requirements, which are more rigorous than standard firearms manufacturing specs. This means tighter tolerances, stricter quality control, and a more durable product built to withstand extended field use and training cycles.
