Red Lion Precision, LLC - #R13A Installation Instructions

Sub2000 Gen1 Replacement Flip-Up Front Sight

Installation Instructions (Make sure gun is unloaded including magazine):

Required Tools : 5/32" Allen Wrench, Flathead Screwdriver

1.If not already done the factory front sight must be removed for install including the Keltec sight bushing if using the Muzzlecomp Adapter or Non-muzzlecomp Adapter for the Keltec sight bushing removed. If using the Non-muzzlecomp Adapter for the Keltec sight bushing left on then only the polymer portion of the factory front sight needs removed.

2.Slide adapter onto the gun (non-muzzlecomp adapters go longer solid circumference end first) and all the way against barrel step shoulder or in the case of the non-muzzlecomp adapter that allows the Keltec sight bushing to be left in place slide till it bottoms out on metal bushing (lip in adapter ID).

3.Orient so that the longitude (parallel to the barrel) milled slot is at 6 o'clock on the barrel. Place the sight body over the adapter and orient linearly so that the back of the front sight is located at the edge of the largest diameter of the Adapter as seen in pic below. (This should place your sight in the right position linearly on the barrel for folding and locking). Snug clamping screws till everything is snug but can still be moved around.

4.To get your sight lined up close so less drastic windage adjustments will be needed its best to have a red dot sight mounted to line it up with and then tighten clamping screws to 6 ft/lbs. Lining up with a laser bore sighter should work as well. If not using these eyeballing should be fine, if off more than you want to compensate with windage just reset.

To adjust the windage place the sight tool (included) in the 4 holes on the face of the windage knob or use dime on the opposite side in windage screw head. Windage knob is marked for bullet impact adjustment direction. Elevation is standard AR15 A2 sight post, place sight tool in the 4 half moons of the sight post and depress the detent to turn the post. Turn clockwise to raise bullet impact and counter clockwise to lower bullet impact. Each windage click is .67" @ 100 yards. Each elevation click is 1.72" @ 100 yards.
