The Miller Precision Arms MPA 300 Guardian is a .300 WinMag in a true AR platform. Absolutely no retraining is needed for this platform, every function is designed to operate exactly as the M16/AR-15.
Machined from certified 7075 t651 structural aircraft grade aluminum, the platform is specifically designed to use aftermarket components such as Armalite style AR 10 forends and buttstocks resulting in a more modular design.
