Element 4.0 Magnesium Chassis

  • Lightweight foldable rifle chassis system for Hunting

    The Element 4.0 Magnesium is an ultra-lightweight modular hunting rifle chassis designed for the backcountry hunter. The standalone chassis, without buttstock or grip, can weigh only 16 oz depending on the action inlet. When configured with a carbon fiber buttstock and carbon fiber grip the system weight is just 28 oz. This ultralight configuration is the first rifle chassis system in the world to weigh under 2 lbs! Now featured with a built-in bubble level, and machined in RRS 1.5" dovetail (Arca-Swiss) in the forend.

    Machined from AZ61A Magnesium, the Element 4.0 Mg retains all the strength and durability for which our rifle chassis systems are known, but at a fraction of the weight! This is the ultimate lightweight, modular chassis platform for the backcountry outdoorsman!

    ** Expected extended lead time due to high product demand. Lead times are 15-20 week for all chassis orders. We appreciate your patience. **
