KOFN (Keyed Optic
Fastening Network)
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.
AK Sight Block Wedge
(SBW) - The SBW replaces the rear
sight leaf on the AK pattern host without any permanent alteration. A rear
sight is incorporated into the wedge.
To install, remove the entire
bolt assembly from the AK. Remove the existing rear sight and place the SBW
into the AK sight block. Screw the two forward fasteners (left/right) into the
front portion of the wedge, but do not tighten completely. Install the steel
T-nut from inside the rear sight block so that the two shoulders are engaged
left/right. Make sure that the steel leveling disc is in the pocket of the
wedge, and then push the wedge down until it sits flat. Then install the
fastener that engages with the T-nut, and do not completely tighten. Using the
provided wrench, adjust the elevation (if required) on the leveling disc to
make the wedge parallel to the barrel. Then carefully tighten the remaining
fasteners. DO NOT OVERTIGHTEN. If everything looks good, take the fasteners
back out one by one, and then reinstall each using the provided thread
locker.
