>>AKA .300 AAC Blackout, .300
BLK, 7.62x35mm
>>1.356 - 1.360 O.A.L.
>>The .300 Blackout is based
off of a shortened 5.56x45mm
case that is necked to .30
calibre. For AR-15 platform
rifles and pistols it only
requires changing the barrel
to go from 5.56 to .300

is to be used at subsonic
velocities in suppressed
firearms. Many bolt action and
single shot rifles are now
being produced in this calibre
as well.
