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 semi-automatic rifle features a 16” 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” 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. Smith-wesson.com.
The M&P15 300 Whisper will also be available with a black tactical upper featuring a 10” free-float quad rail and a Yankee Hill Phantom flash hider. The upper is compatible with any mil-spec AR lower.
