Magpul MOE K2-XL Grip for AR-15, M4

Out of stock

The larger size of the grip also allows proper finger placement in precision shooting, helping improve accuracy.

  • Bigger size supports larger grip needs
  • Approximately 25% larger than MOE-K2 Grip
  • More vertical angle provides optimal hand position for modern shooting techniques
  • Beavertail backstrap for enhanced ergonomics
