The Spike's Tactical ST-15 M4 LE Carbine is yet another quality rifle that is ready for hard, serious use. Spike's Tactical has built a reputation for building some of the highest quality parts on the market from complete rifles all the way down to Mil-Spec components that can be relied on to stand up to just about any environment. When a company gives a lifetime commitment to quality, you know they are serious about it working every time, no matter what.

The Spike's Tactical ST-15 M4LE carbine was designed from the ground up as a fully mil-spec compliant rifle for law enforcement and civilian shooters that need a rifle for personal protection. Since Spike's has made the rifle available to the general public, no longer is a quality rifle limited only for military or law enforcement. Spike's commitment to the civilian market will ensure duty grade rifles are available to shooters of any budget. With features like a 16" 1:7 twist M4 profile barrel chambered for 5.56 NATO that allows the use of more common .223 Remington, a highly reliable carbine gas system, the 12" free float BAR quad rail and a six position collapsible stock, this rifle is ready for anything.
