Smith & Wesson took one of its most well known designs and paired it with an increasingly popular caliber to create the M&P15 300 Whisper. Though chambered in .300 Whisper, it will also safely fire .300 AAC Blackout.

The 300 Whisper builds upon the brand's established M&P line, offering sub-sonic and supersonic capabilities with consistent performance and accuracy. The 300 Whisper is easy to shoot, accurate and versatile—it's a comfortable fit when hunting, at the range for some recreational shooting or deployed for home protection.
