An actual photo about the muzzle
flash of a .50 caliber rifle: An unsuppressed flash is more than revealing in the dark,
especially with a short barreled rifle, like this Liberty Arms LA-50 bolt-action bullpup.
How a muzzle flash is actually born, and how do flash and sound suppressors 'hide' it? The
powder gases contain a lot of unburned gases, which will eagerly burn as a momentary flash
when mixed with the atmospheric oxygen if they are hot and under high pressure. With slow
powder and short barrel, the muzzle residue pressure is high producing a handsome muzzle
flash. A flash suppressor provides the powder gases a minor extra volume in front of the
muzzle to drop their pressure and temperature by expansion to be significantly less eager
to ignite themselves when colliding with oxygen of the air. The same effect can be
accomplished by extending the barrel. Sound suppressors have an exceptionally large
expansion volume, which makes them practically perfect flash suppressors.
The LA-50 aimed, equipped with a
Reflex Suppressor. When compared to the open construction of the standard muzzle brake,
which directs a very notable blast back and to the sides lifting dust, sand, snow and
generally giving the position away very graphically, not to mention the uncomfortable
spotter... the Reflex Suppressor eliminates that by containing most of the gases and
projecting them forwards with very low profile.
Model LAX50 Reflex Suppressor for
the exceptionally short LA-50 bullpup rifle mounts readily to it's flash hider thread.
The well known recoil-action
Barrett M82 with model BT8 Telescopic Reflex Suppressor is almost comfortable to shoot,
regarding the suppressing effect on noise and the absence of pressure shock on shooter and
spotter. Current suppressor model has an integral muzzle brake (not shown in the cut-away drawing of an earlier model) to boost the recoil brake
effect. Because a suppressor adds the mass of the recoil action barrel of the M82, some
shooters use a stiff spiral spring seen in the photo above between the suppressor and the
receiver to further soften the felt recoil.
