Failure to follow these warnings may cause injury or death to personnel.

its own power.
NOTE: Close the ejection port cover if the weapon is not to be immediately fired.
FIRING THE RIFLE
1. Place the selector lever on SEMI-AUTOMATIC.
2. Estimate range to target and adjust the rear sight by rotating the adjuster so that
the desired range setting on the adjuster is aligned with the range index mark.
3. Sight in on the target and acquire proper sight picture and sight alignment.
4. Employing proper breathing techniques, fire the MR762A1 by slowly squeezing
rearward on the trigger until the hammer releases from the sear.
WARNING: Before firing the MR762A1, ensure that:
1. The bore is clear of obstructions.
2. The firearm is pointed only at your intended target.
3. You are sure of your backstop and the impact area beyond.
4. Your hands and fingers are away from the muzzle.
RELOADING THE MR762A1
The magazine in the weapon is empty. The bolt is held to the rear by the bolt catch.
Same procedure as above, except the bolt is already locked to the rear and you must first
set the selector to “SAFE”.
1. Set the selector lever to “SAFE”.
2. Depress the magazine release button with the right index finger or thumb. Remove
the empty magazine from the magazine well. Store the empty magazine in a magazine
pouch.
3. Insert a loaded magazine into the magazine well until the magazine catch engages
the magazine (Fig. 30).
4. Tap upward on the magazine to ensure it is properly seated and tug slightly on the
magazine downwards to ensure the magazine is properly engaged by the magazine
catch. Insert a loaded magazine into the magazine well until the magazine catch
engages.
5. Push the bolt catch in to release the bolt and to chamber a round.
6. The weapon is now loaded and set on “SAFE.”

SECTION 7 — DISASSEMBLY & ASSEMBLY
DISASSEMBLY (FIELD STRIPPING) OF THE MR762A1
Tools Needed: MR762A1 Disassembly Tool (located in the Buttstock), 5mm Allen Wrench
1. Clear the MR762A1
a. Point the muzzle in a safe direction with the finger off the trigger and outside the
trigger guard.
b. Place the selector lever on “SAFE”
NOTE: The MR762A1 has ambidextrous selector lever/safety levers, that is safety
levers located on both sides of the lower receiver. Either lever can be manipulated
and moves the lever on the other side. Unlike many AR-style firearms, the selector
lever/safety levers of the MR762A1 can be placed on the “SAFE” position even if the
MR762A1 is not cocked.
c. Remove the magazine (if applicable) by depressing the magazine release button
located on the right hand side of the lower receiver.
d. Depress the catch located on the charging handle and rack the bolt to the rear two
or three times in quick succession to extract and eject any cartridges that may have
been loaded into the barrel.
e. Lock the bolt to the rear by pulling the charging handle all the way back. Once the
bolt reaches its limit of rearward travel, depress the bottom of the bolt catch located
on the left hand side of the lower receiver.
f. Perform a visual inspection of the chamber area to ensure that no live rounds are
present in the MR762A1 prior to disassembly.
g. Return the bolt to battery (all the way forward) by either depressing the grooved
paddle (top portion) of the bolt catch or by slightly pulling back on the charging
handle until the bolt catch disengages from the bolt and then allow the action spring
to move the bolt forward.
CAUTION: Never attempt to disassemble the MR762A1 with the bolt locked back to
rear. After performing the clearance procedure, always ensure the bolt is forward
before attempting to disassemble.
2. Separating the Upper and Lower Receivers:
a. Rotate the recoil pad counter clockwise one quarter turn and separate the recoil pad
from the buttstock. Remove the MR762A1 disassembly tool (Fig. 33, 34).
