Zenitco B-11 Handguard for AKS-74U and Ten-19K
- $199
Available Options
In short: Zenitco B-11 replaces the original lower handguard on AKS-74U or Ten-19K. Its machined D16T body provides three Picatinny rails, one short lower Basis guide and documented upper-component routes for B-19 and B-19N.
Compatibility matrix
| Host model | Required input | Upper routes | Output interfaces |
|---|---|---|---|
| AKS-74U | Original lower handguard position and original front ferrule | B-19 or B-19N | Three Picatinny rails + mini lower Basis guide |
| Ten-19K | Original lower handguard position and original front ferrule | B-19 or B-19N | Three Picatinny rails + mini lower Basis guide |
Selection checkpoint: B-11 and B-11U are different products with different interface layouts. Select B-11 only for the documented host and original lower mounting position. The manufacturer specifies a deliberately tight fit and warns against filing the fitting surfaces.
Accessory paths
The Picatinny sides accept compatible RK-0, RK-1, RK-2, RK-4, RK-5 and RK-6 grips, A-1 sling mount and A-8 QD sling bracket. The short lower Basis guide provides a direct route for RL-1. B-19 or B-19N completes the documented upper path.
