EPIC is a brand new CZ powerhouse that is developing in their words "The world's most advanced mechanical airguns". 

The EPIC TWO has the ability to mount this adjustable bag rider directly to the tactical stock. Its adjustability allows you to use a rear rest and precisely raise or lower your gun for bench rest shooting. The Textured pad prevents slipping well as being a suitable surface area to use your non shooting hand as a height adjuster when shooting rapid targets
