    Nice rail at a good price. Listed weight (12oz) is just for the rail. The barrel nut, screws and shims bring it up to 15oz.

  2. Cody (verified owner)

    Excellent rail for the price. It’s a little heavier than what I would consider standard these days but it’s nicely made and hard to beat at this price. I’ll be ordering the lightweight version without the rails very soon.

    This was my first purchase from B.King’s and I am a satisfied customer. They ship quickly at a reasonable cost. I look forward to my next purchase. This is an awesome handguard, especially for the price. Relatively light and great finish. Plenty of picatinny rails, M-Lok slots and sling attachment points to add all your accessories. I highly recommend the crow foot wrench to time and torque the barrel nut precisely. (

    Original shipment of order for handguard did not include the barrel nut. Contacted B.King and missing barrel nut was shipped immediately. Excellent customer service. Would recommend B.King to all my friends.

    I bought two of these handguards for my rifles they are excellant, the slim fit gives the gun a whole new feel. Lightweight and ridged with plenty of space for any attachment.
