Byrna Mission 4 Kit

The Byrna Mission 4 Kit is the high-capacity choice for buyers who want a non-lethal launcher optimized for home defense rather than carry. Where the SD and LE are pistol-format, the Mission 4 is a rifle-style carbine. That shoulderable form factor is easier to aim accurately and control under stress, and it stages naturally next to a bed or by a safe room door the way a defensive long gun would.

The headline feature is the 19-round high-capacity magazine. A defensive encounter against multiple threats, or one that demands repeated hits, can empty a 5-round pistol magazine fast; the Mission 4 carries nearly four times the capacity before a reload. It is a .68 caliber CO2 platform firing the same kinetic and pepper projectile family as the rest of the Byrna line, and like all of them it is not a firearm, so no permit or background check applies.

The kit ships ready to deploy with a CO2 adapter, a travel bag, magazines, and accessories. The same legal note carries over: chemical Pepper and Max projectiles face state shipping limits (California kinetic-rounds-only; New York, Wisconsin, Michigan, and Washington DC restricted), and Byrna ships nothing to Hawaii or New York City, while the launcher and kinetic rounds ship almost everywhere. For a defender who wants maximum capacity and the control of a carbine, the Mission 4 is the home-defense flagship of the Byrna lineup.
