- $479
Available Options
In short: The Zenitco B-83 is the lower component of the Joker-3 handguard system for the AR-15 platform. It carries Bazis guides for compatible B-2 and B-2U Picatinny sections and pairs with the matching B-73 upper component.
Compatibility checkpoint
B-83 is documented for the Joker-3 configuration and pairs with the B-73 Joker-3 upper handguard. The complete system also uses the matching mounting nut and a compatible adjustable gas block. B-83 is not a complete standalone Joker-3 system.
Bazis accessory interface
The lower component uses Bazis guides rather than a fixed Picatinny surface. Compatible B-2 and B-2U sections can be positioned on the guides to create Picatinny mounting points only where needed.
