The M4-96D
was designed to meet specific military requirements for a compact, high
efficiency, quickly detachable suppressor for the 5.56mm Colt M4A1 carbine. It
meets the requirements that the suppressor be quickly attached to and removed
from the weapon’s flash hider without tools. The M4-96D suppressor meets and
exceeds SOCOM requirements in a physically small package that only adds 6.25
inches to the overall weapon system length.
The patented
mounting system utilizes Gemtech’s special Bi-Lock™ flash-hider similar to
the conventional M16-A2 bird-cage flash hider. The mounting system reduces
installation and removal to a simple push-and-twist motion. By utilizing our
high-efficiency Bi-Lock™ flash hiders on a variety of weapons, the M4-96D
suppressor can be quickly, easily, and securely moved from weapon to weapon as
the situation requires.
The M4-96D
is currently delivering outstanding service to both domestic and foreign
military and police agencies. In addition to superior sound reduction
capabilities, it is unparalleled for flash reduction. This capability reduces
blooming in night vision devices and can reduce risk in a combustible
atmosphere.
The suppressor and
Bi-Lock mount come with detailed instructions for installation and use.
Full
Automatic Fire Issues:
Suppressors shown with or designed for
machine guns are rated for fully automatic fire. In the case of suppressors
designed for .223 (5.56mm), there are some limitations in the duration of fully
automatic fire due to shortcomings in the ammunition, not the suppressor. 5.56mm
is a unique cartridge. The projectile is physically small and lightweight. The
relatively high muzzle velocity causes excessive barrel heating from friction,
with outside barrel temperatures exceeding 700° F in a 100 round burst. Bore
temperature is considerably higher. The projectile contains a small quantity of
lead, which after a 90 round burst starts to soften and/or melt. The softening
of the lead core results in geometric instability of the projectile, causing
excessive yawing, tumbling, and suppressor baffle contact. These effects are not
normally seen anywhere near this early in larger caliber projectiles, such as
7.62 NATO. Although the suppressor is capable
of withstanding long bursts using ammunition not containing any lead, any lead
containing 5.56mm ammunition will damage the suppressor. Because of the
deleterious heating effect, most weapon manufacturers place serious limitations
on sustained fully automatic fire and state that the barrel is ruined after a
200 round burst.
