SOUND SUPPRESSOR MODEL MK-9K
SERVICING THE 3-LUG MOUNT
™
The Raptor
3-lug mount can be easily disassembled for servicing.
1. Unscrew the knurled cap from the body.
2. Remove the spring-loaded piston from the mount body. Remove the spring.
Service consists of:
1. Replace the O-rings if necessary. The O-ring in the body can be removed
with a dental pick. O-rings are Viton (neoprene must not be used).
2. Thoroughly clean the spring-loaded piston inside and out. Made of stain-
less steel, it can be cleaned with red Scotchbrite or fine steel wool moist-
ened with WD-40.
3. Coat the outside of the piston with grease as well as the inside of the
knurled cap. Lightly coat the inside of the mount body. Suitable greases
include marine bearing grease, available at stores that sell boat trailers.
4. Insert the spring in the mount body followed by the piston (small end first).
Replace the cap and screw hand tight. Do not use thread adhesives.
It is not unusual for a small amount of grease to be forced through the
small vent hole in the knurled cap. This hole is to prevent pressurization of
the mount.
