Zenitco B-33 Receiver Cover Rail - Picatinny Top Cover for AK-Pattern Platforms

Genuine Zenitco | CNC-machined D16T aluminum | Integrated 170 mm Picatinny rail | Does not block iron sights | Black, Desert, Golden khaki & Green

In short: a genuine Zenitco B-33 - a rigid replacement receiver (dust) cover with an integrated Picatinny rail for AK-pattern platforms. It gives you a stable 170 mm top rail (17 numbered slots) for optics while leaving the iron sight line clear. Machined from D16T aluminum alloy; about 215 g. It mounts to a Zenitco handguard for a repeatable, return-to-zero platform. Available in black, desert, golden khaki and green.

The B-33 replaces the standard stamped receiver cover with a milled aluminum cover that carries a full-length Picatinny rail on top. Because it anchors to the handguard as well as the receiver, it holds zero far better than a cover that clips to the receiver alone, so optics stay repeatable through disassembly and reassembly.

The 170 mm rail has 17 numbered slots and sits low enough that standard mechanical sights remain usable. The B-33 secures with five screws - four points onto the handguard and a fifth onto the receiver - and includes a recoil-spring guide for the conversion.

Compatibility Note: The B-33 requires a compatible Zenitco handguard to mount: B-10M, B-10U, B-10L, B-10LS, B-30, B-30U, or a Sport-1 / Sport-1S / Sport-4 / Sport-4S / Leader / Leader-S kit. Confirm you have one of these before ordering.
