Daniel Defense announced on their blog that they will bring an AR-platform carbine chambered for the .300 BLKÂ to the market in 2012. Â The new caliber will be found in the company’s M4 V5 carbine.
The .300 BLK, or .300 BLACKOUT, has gotten a lot of traction during the past year. Â I’ve previously said that I expect we will see a lot of guns and ammunition at the 2012 SHOT Show introduced for this cartridge.
It seems that more and more people are making ammunition, guns and uppers for the 300 BLK (aka 300 BLACKOUT) cartridge. Â The latest that I have found (via the AAC Blog) are the loads from PNW Arms.
PNW Arms manufactures high quality ammunition for handguns, subguns and rifles. Â They are currently offering three loadings in 300 BLK: Â a hunting load, a match cartridge and a subsonic round.
The hunting load uses a Nosler 125 grain ballistic tip bullet with a muzzle velocity of 2200 fps. Â That works out to be about 1343 ft-lbs of energy. Â Pricing on this 300 BLK load is $22.99 for a box/20.
Smith & Wesson announced a new M&P15 rifle chambered in 300 Whisper. Â The S&W rifle will also chamber the popular new 300 BLACKOUT cartridge.
Two versions of the new M&P rifle will be available: one with a Realtree APG finish (shown here) and one with a black finish.  The Realtree version of the M&P15 will feature a 5/8-24 threaded barrel along with an A2-style flash hider, while the black version of the rifle will use a Yankee Hill flash hider.  Both rifles will have a 16″ barrel.
The black version of the 300 Whisper rifle will have a free floating, 10″ quad rail for accessory attachments. Â Both rifles are “optic ready” with a Picatinny rail for the addition of traditional or electronic sights.
