AK-74M: Creating a Picatinny Rail Above the Receiver

Two of our most popular solutions for mounting a Picatinny rail above the AK-74M receiver are the B-13 side mount bracket and the B-33 receiver cover. Both options provide reliable optics mounting, but differ in installation method, weight, and functionality.

The B-13 is the simplest and more affordable solution. It attaches directly to the side dovetail rail and requires no additional modifications. However, not all AK platforms include a factory dovetail rail.

The B-33 receiver cover forms a full-length Picatinny rail and maintains zero even after repeated opening. When paired with compatible handguards like the popular B-10U, it offers extended functionality while reducing overall system weight compared to the B-13 setup.

Conclusion:
B-13 — simple and cost-effective.
B-33 — lighter and more versatile.
