Surplus 5.45x39mm: 7N6 – You Should Have Stocked Up


For the purposes of this article we compared the commercial M855 loading for the 5.56mm to the 1980s Russian 7N6 5.45x39mm surplus round. Both rounds were evaluated out of 16 inch barrels, as that is the most common option to the civilian rifleman. Both the AR-15 carbine in 5.45 and commercial AK-74 variants use this lengh barrel. There are exceptions, such as civilian versions of the RPK-74 (23.2 inch barrel), 20-inch 5.45 barrels and even some 14.5 inch barrels. However, the vast majority are 16-inch, which is the length we will focus on.
