The X-7 Fusion V.2 is a polymer upper and lower receiver set. From Kaiser Shooting Products, this product is around half the weight of its predecessor, is more accurate, and requires less maintenance.

Kaiser says the X-7 Fusion V.2 introduces a newer, better polymer to the upper and lower receiver set in addition to integrating an anti-walk trigger and hammer pin set into the updated design. Kaiser says its proprietary polymer exceeds that of aluminum, offering an impact and shatter resistant build that is also lightweight.
