I couldn’t locate a catalog listing for “Revo Fini Choke Tube Wrench” on major product listings.

If you specifically need the Revo-branded tool, your best bet is to contact Revo or a local gun shop/stockist directly (they sometimes carry brand-specific tools or replacement parts).

If you just need a working choke-wrench, universal and brand-specific tube wrenches that cover common shotgun choke sizes are widely available. Examples I found: Fix It Sticks universal choke wrench, STAHLWILLE tube spanner, and Groz tube spanner.

Universal vs brand-specific: universal wrenches work for many choke diameters/slots; brand-specific wrenches match the original slots and usually fit perfectly.

Material & durability: steel or forged spanners are best if you remove/install chokes often.

Fit & safety: use the correct wrench engagement and moderate force; if a choke is seized, don’t apply excessive torque — take it to a gunsmith to avoid damage.

Fix It Sticks — universal choke tube wrench (example listing).

STAHLWILLE tube spanner — smaller/precision tube spanner option.

Groz tube spanner — common budget option on big retailers.
