Available Options
In short: Zenitco B-18 clamps to the standard rear-sight interface on AKS-74U and Ten-19K and creates a compact Picatinny mounting surface above the receiver area. Its one-piece machined D16T body is supplied with the two mounting screws and hex key required for installation.
Compatibility matrix
| Host model | Required input | Attachment | Output |
|---|---|---|---|
| AKS-74U | Standard rear-sight interface | Two supplied clamping screws | Picatinny rail |
| Ten-19K | Standard rear-sight interface | Two supplied clamping screws | Picatinny rail |
Selection checkpoint: B-18 is documented for AKS-74U and Ten-19K. It clamps to the existing rear-sight interface; do not generalize this fit to similar-looking rear-sight blocks on unlisted models.
Purpose
B-18 adds a compact upper Picatinny position without requiring a separate handguard interface. The low-mass adapter is useful when a short, centrally located mounting surface is preferred.
