Features: The M60E3 7.62mm machine gun is a lightweight, air-cooled, disintegrating metallic link-belt fed, portable or tripod mounted machine gun designed for ground operations like its predecessor, the M60. It is gas operated with fixed headspace and timing which permits rapid changing of barrels. (Associated components: mount, tripod, machine gun, 7.62mm, M122). Slightly different from its "parent," the M60, the M60E3 has a receiver-attached bipod which easily deploys for stability. It has an ambidextrous safety, universal sling attachments, a carrying handle on the barrel, and a simplified gas system that does not require safety wire to prevent loosening. However, the light weight barrel is not safe for overhead fire and is not capable of sustaining a rapid rate of fire of 200 rounds per minute without catastrophic failure of the barrel.

Features: The MK19 40mm machine gun, MOD 3 is an air-cooled, disintegrating metallic link-belt fed, blowback operated, fully

automatic weapon and is crew transportable over short distances with limited amounts of ammunition. It can fire a variety of 40mm

grenades. The M430 HEDP 40mm grenade will pierce armor up to 2 inches thick, and will produce fragments to kill personnel

within 5 meters and wound personnel within 15 meters of the point of impact. Associated components are: MK64 Cradle Mount,

MOD 5; M3 Tripod Mount; and the AN/TVS-5 Night Vision Sight. The MK19 also mounts in the up-gunned weapons station of

the LVTP7A1 model of the AAV and vehicle ring mounts.

Background: The MK19 was originally developed to provide the U.S. Navy with an effective riverine patrol weapon in Vietnam.

A Product Improvement Program was initiated in the late 1970s resulting in the MK19 Mod 3.
