Side Accessory Rails (optional)
The MAX-31A mk2 can be fitted with left and right side
accessory rails for mounting additional accessories. They
are installed by using the threaded holes on the sidesof
the foregrip. Screw threads are #10-32. When installing
the screws, use Loctite 242 on the threads and be careful
not to overtighten the screws.
Attachment of other muzzle devices
The barrel is threaded 1/2-28. The flash suppressor is
torqued to 25 foot/pounds and secured with Loctite
Threadlocker 242 A lockwasher is intentionally not used in
order to ensure the mounting surface of the barrel remains
square and burr free for optional use with a suppressor. If
you choose to replace the flash suppressor with another
type of muzzle device, insure it is designed for use with
9mm caliber bullets.
To prevent marring of the finish, apply masking tape to the
flats on the barrel end and the flash suppressor. To
remove the flash suppressor, attach a ¾" open end
wrench to the wrench flats on the barrel. Attach a
second ¾" open end wrench to the wrench flats on the
flash suppressor. While holding the wrench attached to
the barrel stationary, rotate the wrench attached to the
flash suppressor counter-clockwise.
