Brandon Miller of MPA has been a busy guy. He has his 300 Win. Mag. on an AR platform ready to offer to the public. Miller Precision announced this new rifle on July 4th, 2012 in celebration of freedom. At the time of this writing they are the only company that has a functioning rifle of this type. Best of all the MPA rifle is an AR, this means not training with a new system. This rifle is a natural for military use, or what a great way to play the High Power game, F class anyone?
