bled. Disassembling the bolt can be done in the field, but
remember, there are small parts involved, some of which
are under spring tension.
BE CERTAIN THERE ARE NO CARTRIDGES IN
THE MAGAZINE OR CHAMBER.
DISASSEMBLY —
1. To remove the bolt the firing pin must be in the
cocked position. If it already is, proceed to step 2. If not,
first perform the following: With the rifle unloaded and
the muzzle pointed in a safe direction, cock the firing pin
by raising and lowering the bolt handle.
2. Place the safety in the intermediate position.
3. Raise the bolt and remove it from the rifle as explained
previously.
4. Depress the small breech bolt sleeve lock with your
thumb (See Figure 17) and turn the breech bolt sleeve to
the left (counterclockwise looking from the rear of the
bolt). It takes about six turns for the breech bolt sleeve
(and the connected firing pin assembly) to unscrew from
the breech bolt. Carefully pull the entire assembly out of
the breech bolt.
