Zenitco BN-1 Titanium mounting nut for AR-15 (Joker System)
Genuine Zenitco | VT-6 titanium mounting nut - foundation of the Joker handguard system | Weight 62 g
In short: the Zenitco BN-1 is the genuine VT-6 titanium mounting nut that forms the foundation of the Zenitco Joker free-float handguard system for AR-15 carbines. The B-70/B-80 series upper and lower rails clamp onto it to build a rigid, free-floating forend.
Overview
The BN-1 is the mounting nut that the Joker handguard brackets mount to. It is machined from titanium rather than steel or aluminum, which is where the weight saving in a Joker build comes from.
It replaces the factory mounting nut on an AR-15 upper and forms the base that the B-70 series upper and B-80 series lower brackets clamp onto. Without it the Joker brackets have nothing to attach to.
Compatibility Note: for AR-15 platforms, replacing the factory mounting nut. It is the mounting base for the Joker series upper and lower handguard brackets.
Compatibility: AR-15 pattern upper receivers with standard mounting nut threads. Required base for Zenitco Joker rails (B-70 and B-80 series).
Key Advantages
- Genuine Zenitco VT-6 titanium construction
- Foundation for the modular Joker handguard system
- High strength-to-weight ratio for a rigid, free-floating build

Frequently Asked Questions
What is the BN-1 for?
