The BCM MCMR-13 delivers precision-grade stability and modularity for AR-15 builds demanding maximum accuracy potential. This 13-inch free-floating handguard eliminates barrel contact interference while providing extensive M-LOK mounting real estate for accessories.
What Makes This Different
Bravo Company's MCMR (Modular Chassis M-LOK Rail) features a proprietary barrel nut system that creates a rock-solid lockup with minimal torque requirements. The 6061-T6 aluminum construction maintains rigidity under thermal stress while weighing 25% less than comparable quad-rail systems. Internal cooling channels dissipate heat buildup during sustained fire sequences.
Key Features
- 13-inch free-floating design eliminates barrel harmonics interference
- M-LOK slots at 3, 6, and 9 o'clock positions plus full-length 12 o'clock rail
- 6061-T6 aluminum construction with Type III hard anodizing
- Proprietary barrel nut system with anti-rotation tabs
- Internal heat dissipation channels reduce thermal buildup
- Compatible with standard AR-15 upper receivers
- QD sling mount provisions integrated into design
Field testing demonstrates consistent sub-MOA performance when paired with quality barrels and ammunition. The extended 13-inch length accommodates rifle-length gas systems while providing forward grip positioning for rapid target transitions. Weather sealing prevents moisture intrusion during adverse conditions, maintaining zero retention through temperature extremes.
