CAN BE DANGEROUS AND COULD RESULT IN SERIOUS INJURY, DAMAGE
TO PROPERTY, OR DEATH.
Use of a fi rearm under any circumstance is inherently dangerous. SERIOUS

of fi rearms. Proper training should be obtained from an accredited fi rearms safety
program conducted by a qualifi ed instructor.
Read, understand and follow all of the safety instructions that came with your
fi rearm before attaching your new TWM.
y Always assume every fi rearm is loaded and treat that fi rearm as such.
y Never point a fi rearm at anything that you are not willing to destroy.
y Never service your fi rearm or your TWM when mounted on a fi rearm without
fi rst activating the weapon's safety (if applicable), removing the magazine,
opening the action and physically and visually inspecting to make sure that no
ammunition is installed in the fi rearm.
BEFORE ATTACHING, INSPECTING OR SERVICING THE TWM
y Engage the safety on the fi rearm (if applicable).
y Remove the magazine from the fi rearm (if applicable).
y Open the action and visually and physically inspect the chamber to be sure it
is empty.

INSTALLING THE TWM ON TO YOUR FIREARM
