Frequently Asked Questions

What shotguns does this 12 gauge choke tube fit?

The Biz Raptor Mobil is a standard 12 gauge choke tube designed for shotguns with interchangeable choke systems. It will fit any 12 gauge shotgun with standard choke threading. Check your firearm's manual to confirm choke compatibility before purchase.

Why choose stainless steel over a standard choke?

17-4 PH stainless steel resists rust and corrosion far better than standard steel or nickel-plated tubes, especially in wet conditions or salty environments. It also requires less cleaning and maintenance, and holds up to extended use without degradation.

How do I install this choke tube?

Simply unscrew your existing choke from the muzzle end of your barrel and thread the Biz Raptor Mobil in hand-tight. No special tools or gunsmithing required.
