HVMag.400Leg. Kit

Built from premium aircraft-grade aluminum with a durable protective coating that resists wear and tear. This HV magazine system is a complete upgrade kit that replaces the magazine and bottom metal setup on Ruger American rifles (both Gen 1 and Gen 2 models). This new system swaps out the AR-15 style magazine for a sleek, flush-fitting magazine specifically engineered to feed our high-velocity ammunition. For additional magazines, please click here. Made in the USA. 
 
This is a complete aftermarket kit that includes:
  • A precision-machined and fully assembled bottom metal component.
  • A precision-machined magazine latch (pre-installed for convenience).
  • Two corrosion-resistant stainless-steel bolts.
  • One fully assembled HV magazine engineered for extended length ammunition.
This mag system allows shooters to:
  • Shoot our high-performance 400 Legend HV ammunition in the Ruger American.
  • Torque actions screw to 60 in-lbs. which increases accuracy and consistency.
  • Replace the standard AR-15 style magazine with a purpose-built solution.
  • Enjoy reliable feeding and smooth cycling with every shot.
  • Also works with 6mm ARC, 22 ARC, and 6.5 Grendel.
