Graphic Results from live-fire 7N6 Surplus 5.45x39mm rounds – video included

SPR in 5.45x39mm

In previous articles, I’ve examined the cost benefit of shooting 7n6 surplus instead of commercial M855 5.56x45mm. In this follow-up article, we will examine the various characteristics of the 7N6 surplus round that lend themselves to Serious Social Purposes.

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.
