Wood AR-15 Smooth Long Rail Panel, Walnut

Rail Panels


Black Wood USA’s wood rail panels are a great addition to your AR-15, AR-10 or other pistol/rifle with an MLOK rail. Each rail panel starts as one piece of walnut and is first cut on a CNC machine and then shaped, sanded and sealed by hand. This combination of man and machine production enables the highest level of precision with an unbeatable hand finish. 

Our finishing process highlights the natural grain and color of the wood while protecting it to increase durability. This ensures that our rail panels will perform to the modern sportsman/woman’s standards and hold their classic look.

About The Wood

English Walnut is a classic hardwood that has been used in firearms production for centuries. Its colors range from blonde to dark brown with most pieces having little color variation. The Wood Database rates its Janka Hardness at 1,220 lb. 

No two pieces of lumber are alike and neither are our rail panels. We take pride in the unique patterns and colors found in each of our rail panels and know that you'll love the way the wood complements your firearm. Please note therefore, that the pieces you receive may not look exactly like those shown in the images. 

About Our Collections

Every piece of wood we use is unique. However, to help ensure that the furniture on your rifle provides a uniform aesthetic, we do our best to match all wood furniture pieces within the same wood type. For example, you can rest assured that our Walnut (or Rosewood, Zebrawood, etc) Stock, Grip and Rail Panels will all look great together on your weapon.

The Good and the Bad

Black Wood does excellent work and turns out beautiful products. the 2 long rail panels were smooth and beautiful. looking great on my HM Defense m5 raider pistol...But the mounting holes dont line up on the rail. i screamed an ugly word or two and will have to return their fine product.

    Rail Panels Installation:

    1. Remove rail panels from packaging, leaving the hardware installed.

    2. Position each rail panel with KEYMOD nuts or MLOK T-Nuts through the corresponding rail slots and gently turn each bolt clockwise to lock panel in position.

    3. While applying light outward pressure on the rail panel, use the short end of the supplied allen wrench to tighten each bolt until snug. Caution, do not overtighten screws!

    Care and Maintenance

    Your rail panels are hand sealed with multiple layers of penetrating sealant. After heavy long-term use, wipe on a coat or two of boiled linseed oil to protect the surface and preserve the wood.
