Davidson Defense ECHO-XVIII 18-inch LR-308 .308 Win Rifle Full Build Kit

The ECHO-XVIII 18-inch LR-308 .308 Win Rifle Full Build Kit from Davidson Defense is built for those who demand accuracy, power, and durability in every shot. At its core is the battle-ready 18-inch “Scrubber” barrel—contour-profiled and forged from 4150 Chrome Moly Vanadium, with a manganese phosphate finish that shrugs off abuse and weather like armor. Its 1:10 twist rate and rifle-length gas system offer smooth, consistent cycling, and the 5/8x24 threading is ready to rock a variety of muzzle devices—including the classic GI Birdcage Flash Hider included in the kit.

The “Spectre LP” low-profile upper receiver, precision-machined from 7075-T6 aluminum and finished in anodized black, pairs seamlessly with the sleek, 15-inch M-LOK handguard made from lightweight 6061-T6 aluminum. The included .308 Win bolt carrier group is made from 8620 alloy steel with a nitride finish for slick, reliable function under pressure. Topping it all off is an adjustable carbine stock for personalized comfort and control. Whether you're hitting targets at range or building out your next custom masterpiece, the ECHO-XVIII is your trusted companion for high-performance firepower.
