Basic Principles; Construction - Gemtech MK-9K Operation And Maintenance

SOUND SUPPRESSOR MODEL MK-9K
SINGLE POINT (THREAD) MOUNTING INSTRUCTIONS
1. Be certain that the weapon is unloaded, the magazine removed, the safety
on, and the bolt locked in the open position.
2. Screw the suppressor onto the barrel threads, being careful to not cross-
thread the suppressor.
3. Tighten firmly hand tight. We advocate the use of Blue Loctite to inhibit
unscrewing during firing.
4. Because silencers using single point thread mounting will unscrew during
use, it is the shooter's responsibility to frequently check to be cer-
tain that the suppressor remains tightly screwed on the barrel at
intervals not to exceed 1 magazine.
5. We cannot guarantee alignment on barrels not threaded or gauged by us.
We deny liability for injury or damage caused by misalignment or un-
screwing of the suppressor.
BASIC SUPPRESSION PRINCIPLES
The sound of a firearm discharging is due to the sudden release of high
pressure propelling gases. The purpose of a suppressor is to reduce the gas
pressure by a combination of increasing the volume for gas expansion, de-
creasing gas temperatures, and delaying gas exit from the suppressor.
The MK-9K suppressor is a coaxial design unit, consisting of three
suppression chambers: the inner rear entrance chamber, the inner front cham-
ber, and the outer coaxial chamber. The inner rear chamber diverts pressure
into the outer chamber, offering an exceptionally large volume for initial gas
pressure reduction, trapping, cooling, and exit delay. The baffle stack (cen-
tral core) consists of a steep cone (with a notch in the apex) and a series of
precision formed stainless steel baffles. Stainless steel was used for durabil-
ity and resistance to gas erosion and corrosion. The baffles are optimally
spaced for maximum gas trapping, cooling and delayed gas release into the
atmosphere.

CONSTRUCTION

The entire suppressor is constructed from hard anodized aircraft grade
aluminum alloys with the exception of the baffles in the central core, which
are precision formed from type 18-8 stainless steel for wear resistance and
durability. No packing materials or consumable parts are utilized.
The suppressor can be partially disassembled for cleaning and routine
maintenance. No tools are necessary for this procedure.
