Four-Rails For Maximum Accessory Mounting Versatility; Free-Float Models
Free-float handguard provides four U.S. MIL-STD 1913 Picatinny rails at 3, 6, 9, and 12 o’clock positions for mounting a wide variety of accessories. Top rail aligns with flattop receiver rail to provide an extra-long expanse of uninterrupted rail space without additional cantilever mounts that add complexity and weight to your gun. Two-piece design allows easy installation on original factory barrel nut without removing front sight; factory delta ring must be removed, or low-profile gas block installed. A robust clamp and four anti-rotation alignment bolts lock the forend to the rear of the barrel and actually reinforce the barrel/receiver connection. Large vent holes dissipate heat from the barrel and minimize weight. White alphanumeric identifiers on cross slots ensure easy repeatability of accessory positions when changing configuration from one mission to another. All models, except MRF-MX, have two receptacles on each side rail for 360° push-button sling swivels. Precision machined from high-grade aluminum billet, then Type III hardcoat anodized for strength and corrosion protection, with Teflon® additive for extra resistance to surface abrasion. MRF-C - 7" long, fits carbine-length gas system. MRF-CX – 12" long, extended rail fits carbine-length gas system and has opening for the gas block/front sight. MRF-M - 9" long, fits mid-length gas system and has clearance for factory front sight/gas block and handguard cap. MRF-MX – 10" long, fits carbine- and mid-length gas system; requires low-profile gas block. Does not have sling swivel receptacles. MRF-RX – 13.8" long, fits any-length gas system; requires low-profile gas block.
