In the early 2000’s Advanced Armament Corporation (AAC) was contracted to develop a round with similar ballistics as the common 7.62x39 that could be fired from the government issued M4 carbine. Their solution was the .300 Blackout, or 7.62x35mm. While only requiring an upper receiver swap out – the .300 feeds reliably from standard 5.56/.223 magazines – it was never officially adopted by US military forces. However, the cartridge has captured the hearts and imaginations of many civilian enthusiasts who have chosen the caliber for their custom builds, especially for AR pistols where a close range, manageable “larger” caliber is preferable.

Magtech’s 123 grain full metal jacket round has a muzzle velocity of 2230 feet per second with 1358 foot pounds of energy making this an ideal training and competition cartridge as well as being suitable for civil defense.

Begun in 1990 as a flagship manufacturer of range and training ammunition, Magtech continues to expand in production capabilities as well as product diversity offering a greater selection of purpose built bullets on reloadable brass cases. US shooters have found their bulk prices competitive while smaller portion boxes are the perfect companion to have in their go and range bags.
