Welcome to American Built Arms Company!

The MOD*X Gen III Chassis is a lightweight, durable chassis system that isn’t just ergonomic. It’s accurate…

Since the MOD*X Gen III Chassis does not require “bedding” of the action, its easy for any novice to setup! It also features a low sight to bore axis, this allows you to have the most range of adjustment from your optic for those long range targets. Whether you hunt and want to lighten your load into the field, or wanting to just get the most accuracy out of your bolt action rifle, the MOD*X Gen III is the only answer.
