Atlas Custom Works B-10U Classic AK Railed Handguard for AK Series Airsoft AEG Rifles, Black

The B-10U gives AK players a modern railed handguard that sits somewhere between the old stamped-metal cover and a full rebuild. It keeps the classic AK silhouette — the polymer sides reference the original shape — but puts a full Picatinny rail on top where optics, lights, or lasers actually live.

What it's built from. The body is polymer, which keeps weight in check and means it won't chip when you slide it over the inner barrel. The top is aluminum, so the rail holds up under clamp pressure and doesn't flex when you're tightening accessories. That split-material approach is common on AK handguards for a reason: polymer is easier to install, aluminum is where you need the strength.

How it fits. Six-and-a-half inches covers the standard handguard zone on most AK-series airsoft AEGs — AKM, AK-74, and the platforms derived from both. The polymer body slides over the inner barrel and locks into place, but inner barrel diameter can vary between manufacturers, so check the measurement on your gun before stripping it down. If it fits, installation is a matter of basic tools and about ten minutes. If it doesn't, the seller's listing usually has the spec to verify.

What you mount on it. A low-profile forward mount or a red dot on top is where most players land at this length. The rail accepts standard 1913 accessories — no adapter hunting needed. Side rails are present, but at 6.5 inches they're a "might work" rather than a "fits comfortably" for most accessory profiles. This is a functional upgrade, not a showcase piece.

What this isn't. It's just the handguard — no barrel, no inner barrel, no gas system. If your existing handguard is damaged and you're looking to replace it, this is the part you want. If you're starting a build from nothing, you'll need the rest of the gun to go with it.
