package contains:

step #1 Open bolt to be sure weapon is unloaded.

step #2 Remove bolt by lifting bolt, squeezing trigger and pulling bolt out to rear.

Disassemble bolt. Grasp bolt handle, pull rearward and turn cocking piece 1/4 turn to left, making sure bolt guide bar remains intact. This removes spring tension on bolt. Bolt head and guide bar slide forward as an assembly, exposing firing pin.

note position marks at rear of cocking piece, this aligns firing pin depth correctly and must be returned to exact position for safe operation. Firing pin (under spring tension) may now be unscrewed using fork-shaped end of guide bar slide.

Clamp bolt in padded vise with bolt handle upward. Mark bolt handle base shank (marker or paint). Measure upward 3/16" on knob shank from base of bolt and scribe line on shank. See Sketch A and B.

Re-check 3/16" measurement, leaving room for finish filing (if necessary) later. Cut off bolt handle.

For "non-stepped" (Sketch A) press the 1/2" spacer inside the new Advanced Technology, Inc. bolt handle (supplied). "Stepped" (Sketch B) bolt handles DO NOT require spacer. Place the Advanced Technology, Inc. bolt handle over the cut off "nub" on the original bolt. Clamp in padded vise with the back face of the Advanced Technology, Inc. bolt handle FLUSH against front face of original bolt. (Normal bolt position.)

Using larger #11 drill, carefully "spot drill" area for mount screw - just deep enough to create a centered starting point for the tap drill - Step #8. Cutting oil is recommended.

Using the supplied #21 (smaller) drill bit, drill through the center of the bolt forging. note: be suRe the advanced technology, inc. bolt handle is still in the oRiginal position.

Still clamped, use 10-32 tap, and tap hole through bolt. Deburr and thoroughly clean bolt and handle.

Place Advanced Technology, Inc. bolt handle in place on the forging. Install and tighten supplied 10/32 countersunk machine screw. Use of thread lock is recommended. Finished bolt handle should fit flush with forging when completed.

Reassemble and reinstall bolt in action.

Drill press is recommended for this step. Place the scope mount (holes forward) on receiver flush with receiver ring front face. Square mount on receiver using the flat on the bottom of the receiver-magazine well area.

Clamp securely in position. Double check positioning for squareness. Use supplied larger #11 drill and spot drill rear screw hole. (Spot drill will "mark" center of hole for next step.) With mount still clamped, use supplied smaller #21 drill bit (and cutting oil) to drill through. (Drill slowly so as not to burr inside of receiver below hole.)

With mount still clamped, use supplied 10-32 tap (and oil), to tap through receiver. Without unclamping, clean area and securely screw in the supplied 10-32 x 1/2" screw. Repeat this process for the forward hole.
