BCM® QRF-9 (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 9.24"

  • 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.
  • 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 8.8 oz

  • 1.3 Inside Diameter
  • 2.12" Wide

    QRF Handguard

    I picked up a PSA AR mid length for a very good deal. Picked it up as a gun I would build and make it a little different from what I have. The fit and finish on this guard is second to none for fit and finish and quality.

    Qrf rail

    This is the second rail system from bravo company ive used and im extremely impressed with them they are rock solid and dont move compared to other manufacturers, only complaint is barrel nut is really easy to deform especially when instructions say to torque and break it loose at least 4 times. Have to be extremely careful but i will use them on future builds.

    9” QRF RAIL

    Bought this to fit a Noveske Gen 3 upper. Fit was perfect! Had emailed BCM customer service about fitment and received excellent, timely feedback. The rail feels lightweight and locks up tight. Installment was easy (ish). The long retaining screw kept binding on the rail and I wasn’t sure if it was due to the barrel nut. A little determination and it was all good. I highly recommend this quad rail. I have two other brands that I paid more for and at the BCM price, it doesn’t get any better!

    Bcm qrf

    Love the qrf line and super glad I decided to go this route vs mlok. Feels very good in hand and it's strong dropped rifle from about 6 feet 2 times and not even a scratch ding or dent on the handguard. And the integrated qd mount is very nice anti rotational​ and comes with 2 on each side for more versatility. Only complaint is barrel nut is a bit fragile didn't even really torque it down then tried taking it off with tool and it started to deform then had to file the burrs off so hopefully i don't have to mess with it for a while because I'm going to have to use vice grips to get it off now as I have ramps the tool won't catch anymore.

    Not going to bs about shipping, BCM customer service has always handled that well. Rail is solid, it requires some heating and light tapping to mount and align cross pin holes, but this was surprisingly not difficult and with the indexing piece lined up well with the receiver rail. If maintenance/ barrel change out is required, it can be removed with a little heat and soft mallet tapping as well. Covers a good amount of 10.5 inch barrel with plenty of hand space and feels good in a c-clamp grip. Nice to have a solid, no-nonsense quad rail, and if you compare the price, you get a high quality rail (quality is why you shop BCM) plus the wrench and hardware for a VERY reasonable price. Weight is fine, no issues there, highly recommend,
