Davidson Defense ECHO-XVIII 18-inch LR-308 .308 Win Rifle Complete Upper Build

The ECHO-XVIII 18-inch LR-308 .308 Win Rifle Complete Upper Build from Davidson Defense is a long-range beast built for precision and power. At its heart lies the “Scrubber” barrel—an 18-inch contour profile made from 4150 Chrome Moly Vanadium steel, phosphate-coated and ready to run with a 1:10 twist rate that stabilizes .308 rounds with deadly consistency. The rifle-length gas system pairs with a Recoil Technologies Micro Low-Profile Gas Block to keep your cycling smooth and recoil manageable.

Mounted on the robust 7075-T6 aluminum "Spectre LP" upper receiver, the 15-inch M-LOK handguard made from 6061-T6 aluminum delivers sleek modularity and room for all your favorite tactical toys. Topping it off is a classic 5/8x24 GI birdcage flash hider to keep your shots stealthy, while the nitride-finished 9310 alloy steel bolt carrier group ensures each cycle is as smooth as the last. Built for accuracy, styled for confidence, and ready for the range or the field, the ECHO-XVIII is for shooters who don’t miss—and don’t mess around.
