Bravo Company’s BCM MCMR M-LOK® Compatible Modular Rail handguard gives you a full-length topside Picatinny and seven rows of M-LOK® slots to ensure you have vast expanse of room for mounting accessories. Engineered to minimize bulk, the MCMR is essentially Bravo Company’s popular KMR handguard adapted for the M-LOK® accessory mounting system originally developed by Magpul. The MCMR M-LOK® Compatible Modular Rail handguard gives you a streamlined, clean-looking rifle that is also easy to grasp and maneuver. The MCMR free-floats your barrel, so the weight of the handguard and attached accessories won’t compromise the gun’s accuracy. Engineered for exceptional cross-sectional strength Available in a variety of lengths to fit your rifle & suit your needs Top Picatinny rail is T-marked INCLUDES Proprietary steel barrel nut (same one used on BCM KMR, MCMR and QRF handguards) & installation instructions The BCM MMR M-LOK ® Compatible Modular Rail handguard is fully dehorned so there are no sharp edges to bite into your hand or snag on your gear. It’s machined from 6061 T6 aluminum for the optimum balance of strength vs. weight, then given a hardcoat anodized finish for extra surface strength and corrosion resistance (yes, aluminum will corrode - look at an older car with factory alloy wheels!).
