XLR Element 4.0 Magnesium Bolt-Action Rifle Chassis
Remington 700 Short Action Smoke Carbon Fiber
XLR Chassis Systems — Proven Precision
XLR Industries is trusted by precision shooters for chassis systems that deliver smart design, premium materials, and consistent performance where it counts. Their chassis are widely used in PRS competition, field shooting, and precision bolt-action builds where repeatability and control matter.
Pete’s Pillars is an authorized XLR dealer, and we carry XLR chassis because they meet the standards we expect from equipment we use ourselves—clean fitment, durable construction, and designs that simply work. Choosing XLR through Pete’s Pillars means selecting proven gear from a manufacturer with a strong track record, offered by a dealer that understands real-world precision setups.
The XLR Element 4.0 Magnesium Bolt-Action Rifle Chassis is built for shooters who want extreme weight savings without sacrificing stability or consistency. This ultralight configuration comes in under 2 pounds, making it one of the lightest full-featured bolt-action chassis systems available while still providing the rigidity required for precision shooting.
The chassis body and front section are machined from AZ61 magnesium, a high-strength alloy selected for its excellent stiffness-to-weight ratio. This construction significantly reduces overall rifle weight while maintaining predictable action support and consistent performance. The result is a responsive, well-balanced chassis suited for competition, field use, and lightweight precision builds.
Designed specifically for bolt-action rifles, the Element 4.0 keeps setup straightforward and dependable, allowing shooters to configure their rifle around their shooting style without unnecessary complexity.
Performance in PRS, Field & Range Use
For PRS and positional competition, the Element 4.0 Magnesium provides a stable yet responsive platform that transitions smoothly between barricades, prone, and supported positions. The front section is machined with an integrated RRS 1.5″ dovetail (Arca-Swiss profile), supporting tripods, bipods, and other support equipment commonly used during match stages.
A built-in bubble level allows shooters to quickly verify rifle cant during positional or long-range shots, adding confidence without adding weight.
For hunters and recreational shooters, the ultralight AZ61 magnesium construction keeps carry weight to a minimum while maintaining consistent ergonomics and control. It’s a chassis that feels light in hand but steady behind the rifle.
