The ATOM Magnesium is an ultralight modular rifle chassis designed for the firearms enthusiast or backcountry hunters seeking a compact ultralight chassis. The standalone chassis, without buttstock or grip, weighs only 14 oz for short actions and 15.5 ounces for long actions. When configured with a carbon fiber buttstock and carbon grip the system weight is just 27 oz. The all-new ATOM features the same built-in bubble level, and machined in RRS 1.5" dovetail (Arca-Swiss) in the forend as the Element 4.0 Magnesium.
Machined from AZ61A Magnesium, the ATOM MG retains all the strength and durability for which XLR's rifle chassis systems are known, but at a fraction of the weight! This is the ultralight, modular chassis platform for the backcountry outdoorsman!
A popular choice for those looking for a chassis system that can be configured for target shooting, hunting or competition.
