The biggest of the Heckler & Koch's G36 family is now hitting the retailers. The H&K SL9 (or more known as the SL9SD) is a version of the SL8 which fires the 7.62mm round as compared to the SL8 which is a sporting rifle and fires either the 5.56 NATO or the .223 Remington. In case of airsoft it fires the 6mm just like most airsoft guns. The photo above shows it unboxed at the Umarex HQ in Fort Smith, Arkansas.

If you want to order quickly, you can place your order at Godfather Airsoft, where they're selling it for US$349.99.
