KOFN (Keyed Optic
The KOFN (US Patent Pending)
is a new, innovative return-to-zero mounting system designed to attach
accessories securely and quickly to a host that has an affixed KOFN base.
To operate, install the KOFN
wedge with the wider end forward towards the muzzle. Next, slide the accessory
with its attached base onto the wedge until you detect (audible or feel) that
the push bar snaps into place and securely locks the assembly. The push bar
does not need to be depressed to lock the accessory into place. If rail space
is limited, it can be depressed to allow the base to engage the wedge halfway
down the channel.
Optic plates- The optic is secured to the base with the provided
low strength thread locker. Make sure that any mounting fasteners are long enough
to engage all the threads in the KOFN base. Zero the optic, then remove and
reinstall the base to the wedge to ensure the integrity of the system. Re-check
Shotgun- Mount the Base in the two forward threaded holes on the
receiver. Ensure that the threaded holes
are clean and free of any oil. A cotton swab dipped in a degreaser such as
acetone is recommended. Use the provided thread locker and fasteners to secure
the base to the shotgun. Make sure that the two provided fasteners do not
protrude into the action area where the barrel slides in. Allow the thread
locker to dry completely before subjecting the KOFN system to use.
IMPORTANT- THIS MOUNT ONLY FITS THE 1301 COMP. THE 1301 TAC HAS DIFFERENT SCREW SPACING.
