SIG Sauer To Offer 556 Carbine In 7.62x39
The 7.62x39 cartridge offers a big savings in ammo cost, which should help officers get more range time.

...On average, the 7.62x39 bullet weighs twice that of a .223 and about 35 percent heavier than the heaviest 5.56 NATO rounds. Depending on the amount of powder, a 7.62x39 has a muzzle velocity of 2300-2438 feet per second, while the 5.56/.223 travels at 2750-3800 fps....
...The 7.62x39 makes perfect sense, because it bridges the gap between the far more expensive .223 and .308 chambering. At approximately $5 per box of 20 rounds, that's 25 cents a round and probably 12-18 cents, if purchased in bulk. This price point will enable officers to practice far more than they normally do. Lower price is a great motivator toward more practice.
I have seen it with hundreds of my students. In today's economy, it is sometimes the difference between practicing and not, considering the .223 is twice the price and the .308 is three times the price. The Russians and the Chinese are pumping out the 7.62x39 by the multi-millions. The AK-47 is by far the most widely used rifle platform in human history and continues to be used by over 75 nations to this day. Ammo is plentiful and abundant.
My first introduction to a centerfire rifle was a $65 Chinese SKS with a beat-up wood stock. Price point and availability were the main reasons. Most young shooters are introduced to a .22 rimfire rifle first, and to a cheap centerfire second. I suspect at least two-thirds of the people reading this have owned or currently own an SKS or AK-47 clone....
...I think it is possible for SWAT operators and patrol officers to obtain a "general" degree of accuracy with the 7.62x39 by using a precision platform such as the SIG 556 and augmenting the sight picture with a quality laser light such as an Aimpoint, Crimson Trace, or EOTech-type holographic and illuminated sight systems and red/green dots.
Sighting with your ammo brand will be key and so will extensive practice. With a sugested retail price of roughly $1,700 for the .223 version, the SIG 556 in 7.62x39 fills a needed gap between the more expensive .223 and .308. For agencies and officers with the need for an inexpensive hard-hitting penetrator beyond the .223, the SIG 556 in 7.62x39 is a good option.
