Atlas Custom Works B-12 Railed Upper Handguard for LCT, GHK, and 5KU B-11 Handguards, Desert Tan

If your AK platform came with a B-11-style handguard and you wanted a top rail, the B-12 is the upper half. Atlas Custom Works built it on aluminum, runs it in 3.93 inches of full-length Picatinny, and makes it bolt straight back onto LCT, GHK, or 5KU B-11 handguards — no cutting, no drilling. Drop it on and you've got a reliable rail for a red dot or any optics mount without swapping the whole handguard.

What it does and doesn't do. It sits on the top portion only — side and bottom rails, if the parent handguard has them, stay exactly where they are. You keep the existing handguard shape and grip position, and gain a flat rail up top. An optic won't shift when you're shoulder-checking a reload or working the charging handle.

Desert Tan finishes it off. Anodized in a muted tan that matches the rest of the B-11 furniture set, so the top doesn't look like it wandered in from a different build.

Includes the upper handguard only — mounting hardware for the parent handguard is not listed separately.
