Michigan based Defcom LLC is a new firm that have designed two lightweight grenade launchers which make maximum use of polymers. They are in a sense the Glocks in a world of Beretta M9s.

The DEFCOM XL 79 COMPOSITE is essentially a M79 that has been brought into the 21st century. It weighs 1.41 kg, about half of the original metal-and-wood M79.


The Defcom M79 type product improved grenade launcher receiver, barrel shroud, stock, and front hand guard are manufactured from composite materials. Double action trigger with shotgun-type safety. Matte finish colors: black, desert sand, or woodland green. Top of barrel fitted with MIL_STD 1913 Picatinny rail system. Rear sight is a detachable flip-up scale graduated to 425 meters. Front sight is fixed. Fixed stock launcher has two (2) sling swivels, folding stock has a third swivel mounted on stock hinge. Ambidextrous safety and barrel latch. M16 style pistol grip.

The other Defcom product is the XL 200 under barrel rail mounted launcher. It weights about 40% less than the M203 and M320 launchers.

The XL 200 opens by moving forward, and then tips up at a 40 degree angle, which allows it to be loaded with the new larger low velocity less lethal ammunition.

The Defcom 40 mm grenade launcher is designed to mount to any Mil Spec 1913 Picatinny Rail system. It has a double action trigger with ambidextrous safety and barrel latch. Barrel tilts downward and locks at end of forward travel to permit loading of all low velocity 40 mm ammunition. Titanium breech face. Trigger mechanism is modular and can be easily repaired in field. Barrel meets U.S. military specifications for material and rifling.

XL 200 mounted on the XL-220 standalone mount.

I will be watching this new company with interest to see how their products do.

The Defcom website is not yet up, but the sales office can be contacted at 559.585.1712
