Johnny Stewart Biz Raptor Optima HP 20 Gauge 17-4 PH Stainless Steel Choke Tube

The Johnny Stewart Biz Raptor is a 20 Gauge choke tube designed for shotguns threaded in the Optima HP choke system. Manufactured by Rob Roberts Gun Works as part of the Raptor series, this choke carries MPN 200323 and is built to fit 20 Gauge shotgun barrels.

The Biz Raptor is constructed from 17-4 PH stainless steel, an alloy selected for corrosion resistance and dimensional stability through repeated shooting and choke changes. This construction supports reliable installation and removal with the appropriate choke wrench.

Installation is straightforward: thread the choke into any 20 Gauge barrel fitted with the Optima HP choke system and tighten by hand or with the appropriate choke wrench. Biz is the model designation within the Raptor series lineup of Johnny Stewart choke tubes.
