A Message From Mike...

Crosman Benchrest PistolWelcome to our TKO Airgun Products website.
We began making airgun products about the time PCP airguns were really coming into vogue, around 2005. We started with a few trigger mod parts that we made using water-jet technology. From there, we started getting calls for tuning services and airgun moderators. Since 2008 (when we began keeping production records) we have manufactured and sold over 15,000 airgun moderators. At the first of each month for the last 10 years, we'll try new techniques and processes wherein we try to improve on the performance of the product, while keeping prices affordable. We recently changed the way we bore the collars on the larger diameter moderators to improve barrel fit.

Discovery TKO ModeratorI'm proud to say that the Discovery air rifle and Crosman air pistol moderators we make have hundreds of hours of ongoing development, including internal design changes, stage shape and spacing, step reamer changes ... and the results of that time and effort are evident in the performance of those small diameter TKO Moderators. The lessons learned translate over to our other large diameter products, too.

Thanks for visiting our website, check out our News Blog, Gallery, FAQs, and don't hesitate to call or e-mail to learn more, or just to chat about airguns!

Thanks and best regards
