SOUND SUPPRESSOR MODEL HDM
Before performing any maintenance operation, always
remove the magazine from the firearm, open the action, and
visually ascertain that the chamber is empty and the weapon
unloaded. Failure to do so can result in potential for serious
injury to the user and others in the vicinity.
Always read the warning label on any cleaner or solvent,
and remember that virtually all solvents are inherently dan-
gerous and potentially toxic. Always use adequate ventila-
tion and both skin and eye protection when using organic
solvents.
CLEANING and MAINTENANCE
The HDM suppressor can be totally disassembled by the user for clean-
ing and maintenance. It is strongly recommended that disassembly and
cleaning be performed at intervals of 250 rounds or less. Longer intervals
will result in greater difficulty removing the baffle stack.
1. Remove the magazine from the weapon, open the action, and visually
ascertain that the weapon is unloaded with nothing remaining in the cham-
ber.
2. Remove the 8-32x1/8" setscrew from the bottom rear of the suppressor
tube with a 5/64" hex key.
3. While holding the barreled receiver in one hand, firmly grasp the sup-
pressor tube with the other hand and unscrew.
4. While apart, check (and replace if necessary) the small "O" ring gas seal
in the rear mount. Replacements are available at any hardware or plumb-
ing store and measure 3/4 inch outside diameter with a 1/16 inch thick-
ness.
6. Unscrew the stainless steel sleeve from the barrel covering the barrel
ports. Check and clean the barrel ports if necessary. If any lead is present
in the port, it can be pushed out with a paper clip or other sharp object.
7. At this time, clean the bore of the weapon utilizing any method desired.
