Product Overview
The Rise Armament RA-905 10" handguard is a precision-machined upgrade for AR-15 rifles that blends lightweight ergonomics with modern accessory flexibility. CNC cut from 6061-T6 aluminum and finished in durable black hard-anodize, the RA-905 gives you a slim, free-floating platform to mount lights, grips, rail sections, and other accessories using standard M-LOK slots, while a short 1913 Picatinny rail at the 12 o’clock position preserves quick optic or iron-sight alignment. Engineered to improve barrel harmonics and reduce contact with the barrel, the RA-905 helps translate good ammunition and a quality barrel into measurable accuracy gains.
Key Features & Benefits (SEO keywords included)
10" free-float handguard for AR-15 — compact length that balances accessory real-estate with front-end agility.
Aircraft-grade 6061-T6 aluminum — excellent strength-to-weight ratio for a durable yet lightweight mounting platform.
Black hard-anodized finish — corrosion-resistant, low-glare coating built for years of range use and field conditions.
Full M-LOK compatibility — modular accessory mounting at 3/6/9/12 o’clock positions for lights, bipods, QD mounts, rail sections and more.
12 o’clock Picatinny segment — short top rail forward of the receiver for mounting backup iron sights, offsets, or to provide a continuous sight plane.
Slim, ergonomic profile — comfortable for sustained carry and modern shooting positions; improves natural point-of-aim.
Free-float design — isolates the barrel from handguard contact to preserve barrel harmonics and potential accuracy.
Low weight, high stiffness — engineered cross-sections and ribbing reduce flex while keeping mass down for balanced handling.
Easy installation — ships with barrel nut and hardware (verify retailer package); installs like a traditional slip-on free-float conversion.

Who Should Buy the RA-905
AR-15 builders wanting a clean, lightweight free-float handguard that supports M-LOK accessories.

Tactical users and professionals who want a durable, low-profile rail for lights, lasers, and QD sling mounts.
Precision hobbyists seeking a free-float upgrade that can improve harmonics and group consistency.
Installation & Compatibility Tips
Verify barrel nut interface: The RA-905 installs with a specific barrel nut supplied by Rise Armament — confirm compatibility with your upper receiver and barrel profile (gas block journal diameter). If your barrel requires a different nut or low-profile rail, consult a qualified armorer.
Gas block placement: Because this is a free-float handguard, ensure proper gas port alignment and gas block seating before final torque. If you plan to run a low-profile gas block, confirm clearance dimensions.
Timing & torque: Use a torque wrench and thread locker where specified; follow Rise Armament’s mounting instructions for recommended torque specs. Improper torque can affect zero and harmonics.
Accessory mounting: M-LOK attachments require appropriate hardware and torque—maintain regular checks on accessory screws after initial use. Use preservative or anti-seize on steel screws if operating in corrosive environments.
Real-World Performance & Use Cases
Range & competition: The slim RA-905 gives competitive shooters a fast, ergonomic front end with plentiful M-LOK mounting points for lights, pressure switches, or bipods without compromising balance.
Tactical / duty: Durability and easy QD sling placement make this handguard an excellent choice for duty carbines and patrol rifles.
Hunting & field: The low profile and hard-anodized finish resist scratches and hold up to outdoor environments while preserving the rifle’s handling for off-hand shots.
Precision builds: The free-float design helps minimize external contact with the barrel, improving the chance of repeatable groups when combined with quality ammo and bedding.
Care & Maintenance
Cleaning: Wipe down with a soft cloth; use mild solvent for stubborn grime. Avoid abrasive cleaners that may wear anodize.
Periodic checks: Inspect mounting hardware, barrel nut torque, and accessory screws after initial firing and periodically during heavy use.
Corrosion prevention: Hard-anodize resists corrosion, but if operating in marine or high-humidity environments, wipe down and lightly oil exposed steel hardware to prevent rust.
