GENERAL INFORMATION
ThePATROLMANsuppressor isoneofthefamily ofGemtechExtreme
Duty Silencers specifically designed to withstand the rigorous SOCOM mili-
tary standards for today’s harshest environments. Its lightweight titanium
andinconelconstruction exhibitsgreaterstrengththan regularstainlesssteel
suppressorsandwill outlastmostcompetitors’stamped bafflesforprolonged
engagements.Forweight,durability,andperformance,thePATROLMANsup-
pressoris unparalleled.
ThemodelPATROLMANsound suppressorisofferedina standard1/2-
28 (2A) thread mount only.
All muzzle attachments, including suppressors, will change barrel har-
monics and standing waves resulting in a slight change in point of impact
with the device in place. Because of its light weight, there is less point-of-
impact shift than most comparable sized suppressors for this caliber. The
degreeof changein thepointof impactwillvarywith thespecificweaponand
boththerigidity andmetallurgyofthe barrel.When usedwithstandardweight
law enforcement or military grade barrels, there will be no deleterious effect
on group size.

SAFETY NOTES
1. Always handle weapons in a safe manner and assume they are
loadeduntil theyhavebeen cleared.
2. User installation or removal of the sound suppressor must be ac-
complishedin accordancewiththe instructionscontained inthis
book.
3.Operating Temperatures: Duringuse, thePATROLMANsuppres-
sor absorbs large quantities of heat from the burning propellant
gases. The elevated temperatures can pose a hazard to
personnel and materials that may contact the suppressor
when hot, and the suppressor must be allowed to cool to
ambient temperature before handling.
4. Only use the suppressor completely dry.
5. Before performing any installation or maintenance opera-
tion, 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.

BARREL THREADING
ThePATROLMAN suppressorwasgaugedforalignmentand run-outon
a precision test fixture before shipping from the factory. To ensure proper
alignment, it is imperative that the barrel be threaded properly.
For unthreaded barrels, please refer to the drawing below. To ensure
concentricity, it is important that the barrel be threaded with the threads
coaxialwith theboreand theshoulderat thebackofthebarrel beexactly90°
to the bore axis. See the sketch below. Barrel threading service is available
fromGemtech.
A small (0.06”) thread relief is incorporated into the rear mount of the
suppressor.Athread reliefinthe barrelat theback ofthe threadsis optional.
MOUNTING the PATROLMAN
If present, remove the thread protector. Installation requires that the
suppressorbescrewed handtightonto thethreaded barrel.Ifdesired,a drop
of Loctite 242 (blue) may be used. The threads are standard right-hand.
Never use any type of washer, crush washer, or lockwasher when
mounting the suppressor. Crush washers or lockwashers will cause mis-
alignmentand damagenotcovered bywarranty.
Duringuse, suppressorswillbecome extremelyhot. Donottouch! Fail-
ure to comply may result in burns or melted clothing.
To remove,unscrewthe suppressorandreplacethethread protector.

CLEANING
The PATROLMAN suppressor is constructed of 100% corrosion resis-
tant titanium and inconel.As such, there is no concern about corrosion from
the products of combustion of the propellant gases. We have found no
need for cleaning the inside of the suppressor. We strongly advise
against such efforts or immersion in solvents. Solvents will not drain
completelyand residualliquidmay causeunexpectedpressurepeaks which
can damage the unit. The high flame temperature burns out the majority of
anyremaining powderresidues.
All threads, mounting surfaces, and alignment surfaces should be in-
spected and remain clean. They may be cleaned with a brass brush or
nylonbrushdipped inCLP.
Unlike firearms, it is neither necessary nor desirable to clean centerfire
rifle suppressors. It is acceptable to blow out particulate matter with high
pressurecompressed air. Donot,under anycircumstances,attempt topass
a cleaning patch through the suppressor.
