Built for serious shooters, this 6mm ARC 18" Upper featuring Odin Works and Aero Precision components delivers exceptional accuracy, smooth recoil, and long-range performance. The 18" 416R stainless DMR-profile barrel with a 1:7.5 twist is tuned for modern high-BC projectiles—giving you flat trajectories and consistent hits at distance.
The Odin Works XL adjustable gas system allows precise tuning for optimal cycling and reduced recoil, while the Odin Works Ragna 15.5" M-LOK handguard provides a rigid, lightweight free-float platform. Built on the Mil-Spec upper receiver, and finished with an Odin Works Atlas muzzle brake and nitride BCG, this upper is designed to run smooth, stay flat, and perform under pressure.
