M60E3

• The M60E3 is the lightest product improvement of
  the M60. The M60E3 differs from the standard M60
  in that it is five pounds lighter, has an easily
  deployable bipod mounted to the receiver and a
  carrying handle attached to the barrel features
  twin pistol grips for better control.

8
M60E3 Key Features

• The M60E3 fires NATO standard 7.62mm ammunition.
  Because it is more easily stabilized than other
  7.62mm machine guns, it delivers this fire
  accurately and reliably out to its one kilometer
  maximum effective range. Firing state-of-the-art
  saboted rounds, it is capable of defeating light
  armor at tactical engagement ranges.
• The M60E3, like the M60, may be employed as
  either an assault or unit support weapon. The new
  configuration has several advantages. In the
  assault, the twin pistol grips provide better
  control while firing on the move. Quickly
  deployable bipod legs permit instantaneous
  transition to the prone position for covering
  fire. The combination of the receiver mounted
  bipod legs and the carrying handle attached to
  the barrel greatly facilitate rapid changes of
  hot barrels. For support fire delivered from
  prepared position, the M122 tripod with
  traversing and elevating mechanism is available.
  The M60E3 has been adopted by the U.S. Navy, Air
  Force and Marine Corps and saw extensive use
  during Operation Desert Storm.

M60D Enhanced

• The M60D model differs from the standard M60 in
  that the butt stock and trigger grip assemblies
  are replaced with spade grips and a spade trigger
  assembly. The rear sight is replaced with a ring
  sight to assist in acquiring and tracking
  targets. This permits aimed fire from a pedestal
  or other similar mount. The M60Dis the model
  designed for mounting on wheeled and tracked
  vehicles, naval craft, and as a door gun on
  utility and cargo helicopters. Mounted on pintle
  type assemblies, the M60D provides fire support
  for ground operations.

10
M60D Enhanced Key Features

• The M60D Enhanced incorporates a bipod mounted on
  the front of the receiver instead of mounted on
  the barrel.
• The new bipod is lighter but just as strong as
  the original and reduces the weight and bulk of
  the spare barrels.
• Extra sear notch on the operating rod, which
  prevents a runaway machine gun.
• The M60D Enhanced also features an improved
  feedcover, which permits the user to load the
  weapon with the bolt in the closed position.
• Barrel changing handle eliminates need for heat
  mitten

Comparison Notes

• The lower cyclic rate of the M60E4/Mk43 allows
  for effective single and three round burst fire
  eliminating the need for selective fire.
• Barrowing from military experience within the
  NATO arena MMGs are primarily employed from
  their integral bipod mount, i.e. as a light
  support weapon, and firing techniques are
  effective out to 800 meters. The 800 meters of
  effective range, when an MMG is used as a light
  support weapon is a good method of evaluation, as
  800 meters is about the maximum range a 7.62 ball
  round will penetrate an M1, U.S., steel helmet.
  Helmet penetration is a common aspect of
  determining effective maximum effective range.
  For U.S. 7.62mm NATO ammunition the maximum range
  of ball projectiles is 3,725 meters. However at
  this range, the projectile is not considered
  lethal by military definition.
• The M60E4 500-650 round rate of fire is
  considered leathal at the beaten zone but
  allows for the conservation of ammunition.The
  lighter M60E4 allows for the transport of
  approximately xxx rounds of additional ammunition
  when compared to the M240. This result in
  approximately Xxmin of leathal fire at the beaten
  zone.
• The M60E4 gas cylinder is attached to each barrel
  unlike the other gun systems where the gas
  cylinder is attached to the reciever. This gives
  the M60E4 a significant advantage over the
  competition in that a failure durring combate of
  the gas system can be corrected by a relatively
  quick barrel change. Other units require field
  stripping and cleaning of the gas system which is
  a significantly more time consuming process.
