Built for warriors. Backed by patriots. The Magdump x GOA MK18 SBR isn’t just a firearm—it’s a declaration of freedom, forged through a no-compromise collaboration between Clint “Magdump” Morgan, Daniel Defense, and Gun Owners of America. This mission-ready short barreled rifle is designed for those who demand performance, durability, and purpose in every pull of the trigger.
From its battle-proven RISII MK18 upper to its DD4 lower, every component was hand-selected by Clint Morgan—a Marine Reservist and unapologetic 2A advocate—to reflect the grit, reliability, and conviction of the American spirit. Finished in a custom Rattlecan Woodland Cerakote and outfitted with elite accessories like the EOTECH EXPS2 optic, SureFire Turbo Mini Scout Light Pro, and Daniel Defense Enhanced Trigger, this short barreled rifle is ready for real-world action.
A portion of every purchase directly supports GOA’s fight to defend your constitutional rights. You’re not just buying a firearm—you’re joining a movement. Each short barreled rifle ships with a limited-edition GOA x Daniel Defense challenge coin, a custom Pocket Constitution, and an exclusive patch—symbols of the mission this build represents.
