Smith & Wesson M&P15 in .300 Whisper

Smith & Wesson Corp. announced that the Company has added a new extension to its Military & Police (M&P) Rifle Series with the introduction of the M&P15 chambered in .300 Whisper.  As the first production rifle in the AR platform to be chambered in .300 Whisper (also chambers .300 AAC Blackout), the new rifle offers sub-sonic and supersonic capabilities while delivering consistent performance and accuracy.  Manufactured on the M&P15 platform, the semiautomatic rifle features a 16-inch barrel constructed from 4140 chrome-moly steel.  Both the forged 7075 aluminum upper and lower receivers have been coated with a Realtree APG finish for optimal concealment during hunting applications.  To aide in precise shot placement, the gas-operated rifle benefits from a 1 in 7.5 inch twist, 5R rifling and a crisp single-stage trigger.  Other standard features include a 10-round magazine, integral one-piece trigger guard, dust cover, forward assist and a six-position, collapsible CAR stock.  Designed to operate with or without a sound suppressor, the M&P15 300 Whisper is equipped with a 5/8-24 threaded barrel along with an A2-style flash hider.  The feed ramps and gas system have been optimized to run effectively with a full-range of factory loaded sub-sonic and supersonic ammunition, both suppressed and unsuppressed.  The barrel’s twist rate is compatible with a wide variety of bullet weights from 110 to 220+ grains.  For enhanced reliability, the M&P15 300 Whisper features a chrome-lined gas key and bolt carrier along with a Melonite barrel.  The optics-ready platform is compatible with most sighting systems through the use of the Picatinny-style equipment rail located on top of the upper receiver.  The M&P15 300 Whisper will also be available with a black tactical upper featuring a 10-inch free-float quad rail and a Yankee Hill Phantom flash hider.  The upper is compatible with any Mil-Spec AR lower.  For more information contact Smith & Wesson Corporation at
