Availability: In Stock
The Rise Armament RA-905 10" AR-15 handguard delivers serious modularity without the weight penalty. Built from 6061-T6 aluminum and finished in MIL-A-8625F Type III hard anodize, this slim rail gives you a free-floating barrel design that supports accuracy while staying out of the way of your setup. Whether you're running a precision rifle, a duty gun, or a hunting AR, the RA-905 pairs lightweight construction with enough attachment real estate to mount whatever you need.
What sets this handguard apart is the balance of mounting options. The Picatinny rail up top handles optics, lights, and lasers with standard mil-spec footprint, while six quick-disconnect points wrapped 360 degrees around the profile let you sling-mount, attach backup gear, or route cables without drilling. M-LOK slots give you unlimited secondary mounting positions along the sides and bottom—no rails you don't need, no weight you don't want. The slip-on design is straightforward to install, and anti-rotation and anti-slip geometry keep everything locked in place once it's mounted.
Rise Armament manufactures the RA-905 in Broken Arrow, Oklahoma to AS9100 aerospace standards—significantly stricter than typical firearms production specs. The handguard ships with a steel barrel nut and mounting hardware. A 100% product guarantee and lifetime manufacturing warranty back the work.

Yes. The RA-905 is a standard slip-on handguard designed for AR-15 platforms. It includes a steel barrel nut and mounting hardware for installation.
The Picatinny rail runs along the top of the handguard and uses standard mil-spec rail space for mounting optics, lights, and other accessories. M-LOK slots are integrated into the sides and bottom, offering a lighter, lower-profile alternative that lets you mount accessories at any point along the handguard without full rails.
A free-floating barrel—one that doesn't contact the handguard—eliminates external pressure that can affect how the barrel vibrates during firing. This is why precision rifle builders use free-floating designs. The RA-905 supports this configuration, but actual accuracy gains depend on your entire rifle setup, ammunition, and technique.
Yes. The six quick-disconnect points span 360 degrees around the handguard, giving you multiple sling-mount options along the sides, bottom, and top.
