​I specialize in custom parts for Crosman 13XX, 22XX and specific PCP models like Benjamin Discovery and Maximus. These are the most popular airguns in the world for customization. 13XX includes Crosman 1377, 1322, 1300KT and related models like the 2289G Backpacker and PC77. 22XX includes 2240, 2250, 2260 and related models like the 2300T, 2300S, 2300KT and 2400KT. For PCP the focus is on models that evolved from 22XX. This includes Discovery, Maximus, Fortitude, Challenger, Marauder Pistol, 1701P and 1720T. All of these models share interchangeable parts to one degree or another.


 Managing this business is extremely time-consuming. Answering messages, packaging, shipping, maintaining multiple websites and online stores, parts design & production, performance testing, destructive testing and building custom guns to list in my online stores is a never-ending task. I rarely have time to do repairs, tuning or custom builds for customers and generally turn away those requests. I also don't make custom parts by request, what I have listed is what's available.I do service and repair all parts and guns bought from me. All work must be shipped, my shop is not open to the public, no exceptions.


 I plan to add more technical information, instructional videos, new parts and custom guns as often as possible. My mission is to help expand the world of airguns to a higher level of performance and popularity.


 If you have any questions feel free to contact me.
