FMA CNC LOWPRO 45° Handguard RIS Rail - Black
FMA CNC LOWPRO 45° Handguard RIS Rail - Black is a CNC-machined aluminum handguard featuring a 20mm RIS top rail and 45° side rails, designed for M4/M16 platforms. Its offset 45° low-profile geometry minimizes snag and enhances grip flow in tight environments.
Construction and geometry
- Material: Aluminum (CNC machined)
- Finish: Black hard-anodized
- Rail system: Top 20mm RIS rail plus 45° side rails
- Configuration: Offset 45° low-profile design
- Weight: Approx. 150–180 g
- Included mounting hardware: Yes (as required by the handguard)
Key benefits and use cases
- Compact, rugged mounting platform for CQB and milsim on the FMA CNC LOWPRO 45° Handguard RIS Rail
- Integrated 20mm RIS top rail with 45° side rails enables foregrips, lights, lasers, and other accessories
- 45° low-profile configuration reduces snag and improves grip flow in confined spaces
- Black hard-anodized finish provides durability and corrosion resistance in field conditions
- Lightweight design minimizes front-end fatigue during extended games
- CNC-machined aluminum construction ensures precise tolerances and reliable fit
Compatibility and mounting
- Compatibility: Most M4/M16 platforms with RIS handguards
- Mounting: Included hardware (as required by the handguard)
Brand context and usage guidance
- FMA provides precision CNC components for modular rifle setups; this handguard maintains consistent alignment with other RIS-compatible accessories
