In reply to the discussion: Rifle identified in Dallas shootings as an SKS. Semi-auto - typically 10rnd fixed mag EDIT - OR NOT. [View all]Straw Man
(6,947 posts)... was developed in WWII by the Russians, but didn't go into service until the late '40s. It didn't last long in Red Army service; the advent of the AK-47 made the SKS obsolete by virtue of the AK's detachable magazine and full-auto capability.
The SKS is not by any definition an "assault rifle," since that military definition designates a rifle that can fire in full-auto mode, nor is it an "assault weapon," since that legal definition only applies to semi-auto rifles that have detachable magazines. The standard SKS does not. If modified to take a detachable magazine, it would be classified as an "assault weapon" in some states and in proposed federal legislation. Hence the interest in the configuration of the Dallas shooter's rifle.
The SKS is functionally identical to the American M1 Garand, a WWII-era rifle that has been sold to US civilians through the government-chartered Civilian Marksmanship Program ever since it was phased out as military issue in the late '50s.

Both the SKS and the Garand are semi-auto rifles that have internal fixed (non-detachable) magazines. The Garand holds eight rounds, the SKS ten.
