Straight Talk: NEW Ruger AR-556 MPR 450 Bushmaster

    MPR 450 Bushmaster

    There is a new kid on the block of black rifles, and that is the Ruger AR-556 MPR 450 Bushmaster. This AR-15 will look to fill a niche market for AR-15 aficionados that also love to hunt. In some regions of the country, if you are hunting various game, local wildlife authorities do not allow center-fire rifle cartridges; that is, unless if they are straight-wall casings. For what is deemed safety reasons, this typically relegates hunters to using revolver cartridges or older lever-action calibers. Most of which either lack velocity, power, or both.

    For that reason, an AR-15 in something like .450 Bushmaster can provide a consumer with a semi-automatic platform, larger capacity magazines, and more velocity and energy when connecting on game. With all of those reasons in mind, it makes for perfect timing to announce the AR-556 MPR 450 Bushmaster leading into many of the fall hunting seasons. To give a better description and outline of the features of this rifle, Ruger provides all of the specifications for the build below:

    • Lower Receiver is fitted with Magpul® MOE® Grip and MOE SL™ Collapsible Buttstock on the Mil-Spec Buffer Tube.
    • Handguard is Free-Floating for Accuracy and the Slim, 15″ Length provides Enhanced Ergonomics and Support.
