MPA300 Guardian .300 Win. Mag. AR-15

The MPA300 Guardian is my pick for best rifle at Media Day (the range day that proceeds SHOT Show). The elegant looking is approximately the same size and weight of the Army’s .308 Win. M110 Semi-Automatic Sniper System but being chambered in .300 Win. Magnum it has up to twice the range and packs a much greater punch.

Sitting down to shoot the MPA300, and having shot many hunting and tactical bolt action rifles in my time, I braced myself for the recoil. I was very pleasantly surprised. The recoil is light. The Stoner gas system soaks up much of the recoil not canceled out by the muzzle brake.

The MPA300 utilizes as many standard AR-15 or AR-10 parts as possible. The receiver is about an 1″ (maybe slightly more) longer than an AR-10 rifle to accommodate the larger magazine well but otherwise looks and feels the same. The stock is a Magpul PRS (7.62) and the handguard is a Precision Reflex 208 AR Delta. The barrel is 20″ long that MPA machine from a Kreiger barrel.  The chambers are cut by hand for the best possible bore alignment. It has a rifle-length gas system.

The MSRP is $5,399.
