Genuine Zenitco | Milled AK-pattern dust-cover with a full-length 170 mm Picatinny rail | Black / Desert / Golden khaki / Green
In short: the Zenitco B-33 is a milled D16T aluminum dust-cover with a full-length 170 mm Picatinny rail - a rigid, return-to-zero optics platform for AK-pattern carbines that still leaves the iron sight line clear. It mounts through a Zenitco handguard.
Overview
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.

Frequently Asked Questions
What is the Zenitco B-33?
A genuine Zenitco replacement receiver (dust) cover with an integrated 170 mm Picatinny rail for AK-pattern platforms - a stable, return-to-zero optics mount.
What do I need to mount it?
A compatible Zenitco handguard: B-10M, B-10U, B-10L, B-10LS, B-30, B-30U, or a Sport-1 / 1S / 4 / 4S or Leader / Leader-S kit. It anchors to both the handguard and the receiver.
Does it block the iron sights?
No - the rail sits low enough that standard mechanical sights remain usable.
Which handguards is the B-33 compatible with?
It mounts on Zenitco handguards only: B-10M, B-10U, B-10L, B-10LS, B-30, B-30U and the Sport-1, Sport-1S, Sport-4, Sport-4S, Leader and Leader-S kits. Five screws tie the rail to the handguard, so a factory handguard will not work.
Does it replace the standard receiver cover?
Yes. The B-33 takes the place of the factory receiver cover. The standard cover and recoil-spring assembly come out, the supplied rear stop with guide goes in, and the B-33 is then fitted to the handguard.
Is this a genuine Zenitco part?
Yes - an original Zenitco part with guaranteed US delivery.
