Atlas Custom Works B-31L Sport AK Gas Tube Cover for B-10L Sport Handguards, Black

A lot of AK handguards leave the gas tube bare, which is wasted real estate. This aluminum gas tube cover from Atlas Custom Works turns that gap into a full Picatinny rail, so you can mount optics, lasers, or other accessories without adding a full handguard swap.

It's built to fit 5KU B-10L Sport handguards, and it works with DL-1 handguard extenders when you're running one. The cover sits on top of the gas tube and bolts down like a standard gas block mount. No welding, no fabrication, just a direct install that adds usable rail length to an otherwise blank space.

Aluminum alloy construction keeps it light while holding zero on your optic. This isn't a scope — it's a mount, so the stability comes from whatever optic you pair it with. If you're building around a B-10L Sport handguard and need more rail real estate than the handguard itself provides, this is the straightforward way to get it.

Ships in black. Includes the gas tube rail cover only — mounting hardware and optics sold separately.
