The Dead Air P-Series Fixed Barrel Spacer is a must-have accessory for owners of Dead Air P-Series suppressors who run them on fixed-barrel firearms. Designed to replace the factory piston spring, this spacer ensures proper alignment and safe, consistent performance when shooting from carbines, subguns, or other platforms without a moving barrel. Suppressors optimized for handguns often rely on a piston spring to accommodate the cycling of a tilting barrel. On fixed-barrel setups, however, that same spring can cause unnecessary wear or damage. The Dead Air P-Series Fixed Barrel Spacer eliminates that issue by creating a solid interface-delivering reliability, longevity, and peace of mind. Compact, lightweight, and precision-engineered, it's the simple solution that keeps your Dead Air setup running flawlessly across multiple platforms. Specifications: Compatibility: Dead Air P-Series suppressors Use Case: Fixed-barrel firearms Design: Direct replacement for the standard piston spring Construction: Durable steel spacer, built for long-term reliability Purpose: Ensures safe suppressor operation on non-tilting barrel systems
