BCM® QRF-7 (Quad Rail Free Float Handguard)

Featuring the same industry leading barrel nut and lock up design as originally introduced on BCM's evolutionary KMR handguard, the QRF Series of handguards gives the shooter modularity in the picatinny (MIL-STD-1913) platform. Includes T, L, R, and B recoil slot markings on all four rails to aid in repeatable set up for the end user.

This proprietary patented mounting system (US Patent 8904691), includes a mechanical index to the 12:00 rail and positions mounting hardware to mitigate the movement caused by heat generated by the weapon system.

Actual length is 7.24"

  • Free Float Quad Rail eliminates loads from barrel, reducing the deflection for more accurate shooting.
  • Precision Machined Aerospace 6061-T6 Aluminum Alloy, for high strength and lightweight.
  • Proprietary engineered profile offers additional cross sectional strength.
  • Includes 4 QD Sing Swivel Sockets, (limited rotation)
  • Steel Barrel Nut (same KMR, MCMR, and QRF series), to resist movement under heat.
  • Hard Coat Anodized per Mil-A-8625F, Type III, Class 2
  • Handguard alone weighs 6.9 oz
  • Handguard mounting hardware 2.3 oz
  • 1.3 Inside Diameter
  • 2.12" Wide

    Solid 1 piece free float rail.

    Been looking for an excuse to try this rail, and I finally got one. Rail mounts up nicely. Just read the instructions, and it's no problem. Rail dimensions are just right. Similar to a KAC RAS. Pics don't show it, but on the carbine, the front hand guard cap is not needed. The rail is really like 7.25" so you get that little extra length behind the front sight base. Price is great too.

    I hesitated for way too long and made one unnecessary purchase before finally picking up this BCM handguard.
    I didnt think the quality I received out of their LPK package was going to be out of all of their products.
    Will replace other parts in the future with BCM products.
