Available Options
In short: The Zenitco B-30U is a one-piece D16T aluminum lower handguard with fixed Picatinny along the bottom and one Bazis guide on each side. A compatible B-31-family upper component is required for the documented installation.
Purpose and interfaces
The bottom Picatinny rail accepts compatible accessories directly. The side Bazis guides accept matching accessories or B-2, B-2L, B-2M and B-2U Picatinny adapters.
The manufacturer requires one compatible upper component: B-31 V2.0, B-31S V2.0 or B-31N. Select that component for the exact platform; it is sold separately.
