The K3B-MIL4 Carbine Series

Formerly LE Only

Starting at $839.00


The K3B-MIL4 is the standard K3B carbine updated with the current military military carbine upgrades. Inluded are the lightweight barrel contour under the handguards, the "step-down" notch in front of the front sight base assembly for the installation of the M204 40mm Grenade Launcher in the military/LE application, or 37mm flair launcher for less than lethal civilian applications.

Keep in mind that this little carbine may be "like" the current military infantry carbine, but in many ways it is so much better! We have upgraded the barrel to a 416 stainless steel material, with a precision, match-grade, button rifled bore with a 1x9 twist. This barrel will be just as reliable, longer lasting, easier to clean, more resistant to corrosion, and WAY more accurate than any "original" barrel of this type from any other manufacturer.

K3B-MIL4 carbine in various configuration are currently in use by law enforcement and military units around the world, including opperatives in the Unites States Army Special Forces. If they trust their lives with this rifle, why shouldn't you?
