SOUND SUPPRESSOR MODEL HMR and WMR
Failure to follow installation and maintenance instructions
detailed in this manual can result in potential for serious
injury to the user and damage to the weapon. Firearm sound
suppressors are user attached firearm muzzle devices, and as
such are subject to improper attachment unless the proper proce-
dures outlined in this manual are followed.
The manufacturer is not responsible for improper usage of this
product. This product is potentially dangerous, and as such it is the
user's responsibility to understand and implement its proper use. If
you do not understand the instructions in this manual, please con-
tact the manufacturer for further clarification.
The HMR and WMR are highly advanced suppressor design optimized
for maxi-mum accuracy and minimal back pressure in a compact envelope.
They are 100% constructed of 300 series stainless steel. No packing mate-
rial or wipes are used in these units. Designed to meet requirements for a
compact, highly efficient muzzle suppressor, they have been optimized for
maximum efficiency dry, maximum accuracy, and minimum first round "pop"
(the amount the first round is louder than subsequent rounds). The HMR and
WMR suppressors are engineered to reduce the sound level of the muzzle
blast significantly below the bullet flight noise and makes the weapon hear-
ing safe under the requirements of MIL-STD-1474D and OSHA.
The HMR is intended only for the .17HMR and .17HM2 rimfire cartridges.
The WMR is intended for the popular .22 Magnum rimfire cartridge.
Due to the fragile and highly frangible nature of the ultra high velocity .17
rimfire bullet, grease, water, or other coolants in the suppressor may cause
the bullet to fragment within the suppressor.
Both the .17HMR and .17HM2 cartridges were introduced by Hornady.
The first was the .17HMR, which was a .22 Magnum cartridge necked down
to .17 caliber with a unique 17 grain Hornady V-Max projectile. It became an
instant hit with small varmint hunters due to its flat trajectory and devastating
effect on small targets. Although the bullet has negligible weight, the velocity
of around 2,600 fps assured essentially total fragmentation of the bullet in the
