(Use with Reference Diagram For Red Lion Precision #R12A Front sight)

-Tools Needed: 5/32 Allen Wrench, 3/32 Allen Wrench, & Large Flathead Screwdriver

1. Make sure that magazine is removed and firearm is unloaded. Please be sure to follow all safety procedures when handling firearms.

2. Remove factory front sight by following the instructions provided by Kel-Tec via their Sub2000 Gen2 Safety, Instruction, and Parts Manual. See Kel-Tec’s website for PDF download if you don’t have the Sub2000 Gen2 Safety, Instruction, and Parts Manual.

3. Make sure muzzle threads are clean and set screw is not protruding into ID of #R12 Front Sight. Screw the #R12 Front Sight onto the 9/16-24 threads with end with set screw toward the receiver until it bottoms out. Back off just enough to achieve approximate proper position radially (will be less than one revolution).

4. Tighten down both 10-32 screws using a 5/32” allen wrench and a large flat head screw driver in the screw post slot so that the front sight is snug but can still be positioned radially by hand. Once positioned correctly radially, tighten both 10-32 screws to 5-6 ft/lbs.

5. Flip top of sight up if not already done so for allen wrench access and then snug down 10-24 set screw using a 3/32” allen wrench.

6. Installing Timing Nut.-Care should be taken to keep supplied wrench on hex of Timing Nut.

-If a muzzle device is not being used, just finger tighten Timing Nut against front sight with hex flange facing toward muzzle and reinstall factory thread protector that was removed previously. Timing nut can be held with supplied 11/16” wrench while tightening thread protector.

-If a muzzle device is being used, then finger tighten Timing Nut against front sight with hex flange facing toward muzzle. Thread on muzzle device until it bottoms out on Timing Nut, then if muzzle device is not oriented correctly radially, back off muzzle device until proper radial orientation is achieved and then back off Timing Nut until it bottoms out on muzzle device. Hold Timing Nut with supplied 11/16” wrench while tightening down muzzle device to muzzle device torque recommendations. (ATTENTION: Kel-Tec specifies 10 ft/lbs MAX)

7. Installation should now be complete.
