  1. M68 & AN/PAQ-4A

  2. TOPICS • M68 SIGHT UNIT • AN/PAQ- 4A

  3. REFERENCE • TM 9-1240-413-12&P • TM 11-5855-299-12&P • TM 9- 5855-262-10-2 • TM 9-1005-319-10 • FM 23-9 • FM 7-8

  4. M68SIGHT UNIT • SIGHT ELEVATION ADJUSTMENT SCREW ADJUSTMENT CAP BATTERY BATTERY CAP FRONT LENS COVER ADJUSTMENT CAP WINDAGE ADJUSTMENT SCREW ROTARY SWITCH REAR LENS COVER TORQUE KNOB

  5. M68MOUNT • MOUNT RAIL O-RING MACHINE SCREW

  6. M68 SIGHT UNIT + LIGHT WEIGHT + BOTH EYES OPEN FIRING + NO CENTERING OR FOCUSING REQUIRED + REGGED PRECISION ELECTRONIC OPTICAL RED DOT SIGHT + RED AIMING REFERENCE( COLLIMATED DOT) • NON TELESCOPEIC THE SIGHT UNIT MUST BE MATCHED WITH THE SAME WEAPON AND ON THE SAME SLOT ON THE RAIL SYSTEM

  7. INSTALLING ONM16A2 • INSTALL BATTERY A. REMOVE BAT CAP B. INSERT BATTERY WITH THE POSITIVE(+) END TOWARD CAP • INSTALL SIGHT ON THE MOUNT ON M16A2 A. INSTALL MOUNT ON THE M16A2 HANDLE B. INSTALL SIGHT ON THE MOUNT

  8. INSTALLING ONM4 • INSTALL BATTERY A. REMOVE BAT CAP B. INSERT BATTERY WITH THE POSITIVE(+) END TOWARD CAP • INSTALL SIGHT ON RAIL SYSTEM A. REMOVE CARRYING HANDLE B. PUT SIGHT UNIT ON THE RAIL SYSEM IT MAY BE PUT ON IN ANY POSTION

  9. ZEROING • THE IRON SIGHTS MUST BE ZEROED FIRST 1. OPEN THE LENS COVERS 2. TURN ROTARY SWITCH UNITL RED DOT INTENSITY CONTRAST SUITABLY WITH TARGET BACKGROND 3. GET A ROUGH ESTIMATE OF ADJUSTMENT REQUIRED. THE RED DOT SHOULD APPEAR ON THE TOP OF THE FRONT SIGHT POST 4. IF ADJUSTMENT IS REQUIRED GO TO NEXT STEP

  10. ZEROING CONT NOTE EACH CLICK IS EQUAL TO 4MM MOVEMENT AT A RANGE OF 25M 5. INSERT ADJUSTMENT TOOL(COIN,SCREWDRIVER, KNIFE) IN ADJUSTMENT SCREW SLOT. TURN ADJUSTMENT SCREW AS FOLLOWS TO MOVE THE IMPACT OF THE ROUND: RIGHT TURN THE WINDAGE SCREW COUNTERCLOCKWISE LEFT TURN THE WINDAGE SCREW CLOCK WISE UP TURN THE ELEVATION SCREW COUNTERCLOCKWISE DOWN TURN THE ELEVATION SCREW CLOCKWISE

  11. ZEROING CONT 6. REPEAT STEPS 3 AND 5 UNTIL THE SIGHT IS ROUGHLY ZEROED 7. CONFRIM ZERO BY FIRING 3 SHOTS CHECK IMPACT OF ROUNDS FOR ACCURACY. YOU MUST HIT 5 OUT OF 6 IN A 3CM CIRCLE. 8. IF ZERO IS ACCURATE FIRE 3 MORE SHOTS TO CONFIRM. IF NOT REPEAT STEPS 5 AND 7 UNTIL COMPLETE

  12. ZEROING CONT 9. TURN ROTARY SWITCH TO OFF 10. CLOSE LENS COVERS

  13. EMPLOYMENT OFM68 PLACE THE RED DOT ON THE TARGET AND SQUEEZE THE TRIGGER UNTIL THE TARGET IS ALIMATED EMPOLY THIS WEAPON SYSTEM AS YOU WOULD AN M16A2 OR M4 WITH IRON SIGHT

  14. QUESTION ON M68 ?

  15. OWN THE NIGHT

  16. WARNING ALTHOUGH THE INFRARED LIGHT EMITTED BY THE AIMING LIGHT IS CONSIDERED TO BE EYE SAFE, PRECAUTIONS MUST STILL BE TAKEN TO AVOID EXPOSURE TO THE INFARED BEAM OF LIGHT.

  17. AN/PAQ-4ACAPABILITIES • INCREASES THE ACCURACY OF YOUR FIRE AT NIGHT • ONLY SEEN WITH NVG ON • A PULSING BEAM OF LIGHT • THE BEAM IS INFERRED ONLY • 1ST ROUND ACCURACY • 150 METER MINIMUM AGAINST A MANSIZED TARGET

  18. AN/PAQ-4ACHARACTERIS • EASILY MOUNTED TO THE M16A2/M4 • EASY TO MAINTAIN • LIGHT WEIGHT

  19. AN/PAQ-4A 1. BATTERY COMPARTMENT AA BA-1567/U OR BA-5567/U • BATTERY CAP • SCATTER SHIELD • AZIMUTH ADJUSTER • ELEVATION ADJUSTER • ON/OFF SWITCH • MOUNTING FOOT

  20. AN/PAQ-4ACOMPONENTS • OPTICAL ELEMENT • ALIGNMENT DEVICE • MOUNTING BRACKET

  21. MOUNTING THEAN/PAQ-4A • INSERT THE BATTERIES INTO THE BATTERY COMPARTMENT • POSTION THE AIMING LIGHT ON THE MOUNTING BRACKET • SECURE THE AMING LIGHT OT THE BRACKET • PLACE THE WEAPON BETWEEN YOUR KNEES WITH BARREL FORWARD

  22. MOUNTING THEAN/PAQ-4A CONT • INSERT THE MOUNTING BRACKET INTO THE RIFLE HANDLE. MAKE SURE THE ALIGNMENT PIN ON THE BRACKET IS FULLY RETRACTED AND FLUSH WITH THE TOP SUFACE OF THE BRACKET • ADJUST THE MOUNTING BRACKET TO LINE UP THE ALIGNMENT PIN WITH THE HOLE IN THE RIFLE HANDLE.

  23. MOUNTING THEAN/PAQ-4A • TURN THE THUMB WHEEL CW TO FULLY ENAGE THE ALIGNMENT PIN IN THE HOLE OF THE RIFLE HANDLE • USING THE THUMBWHEELCONTINUE TIGHTING UNTIL THE AIMING LIGHT BRACKET ARE FIRMLY MOUNTED ON THE RIFLE • NOW YOU ARE READY TO ZERO

  24. ZEROING AN/PAQ-4A • MARK THE DESIGNATED STRIKEING POINT 3 SQUARES DOWN AND 3 SQUARES TO THE RIGHT OF THE CENTER OF THE ZERO TARGET • SHADE IN A 4 X 4 SQUARE REIGION WITH THE STRIKE POINT AS THE CENTER. THIS REIGION IS CALLED THE DESIGNATED STRIKE ZONE

  25. ZEROINGAN/PAQ-4A CONT • ATTACH THE 25 METER ZEROING TARGET TO A FLAT SURFACE AT 25 METERS • PREPARE THE SECOND AIMING LIGHT WHICH IS CALLED THE BORESIGHT • REMOVE SCATTER SHIELD FROM BOTH AIMING LIGHTS.

  26. ZEROINGAN/PAQ-4A CONT • SCREW ON THE BORESIGHT APERTURE TO THE FRONT OF BOTH AIMING LIGHTS • SCREW THE ALIGNMENT DEVICE INTO THE BATTERY CAP OF THTE BORESIGHT UNITL FULLY SEATED

  27. ZEROINGAN/PAQ-4A CONT 8. ROTATE BOTH AJUSTMENT KNOBS FULLY CLOCKWISE(CW) TO THE END OF TRAVEL. NOW ROTATE EACH KNOB BACK 5 TURNS COUNTERCLOCKWISE(CCW) AND ALIGN THE WHITE DOT ON EACH KNOB WITH THE FRONT FLANGE. THE BORESIGHT IS NOW IN ITS NEUTRAL POSITION.

  28. ZEROINGAN/PAQ-4A CONT • TURN THE BORESIGHT TO THE FULLY ON POSITION AND INSERT IT IN THE BARREL • WHILE WEARING NVG, BRACE THE RIFLE SUCH THAT BORESIGHT SPOT IS HELD STEADY ON THE CENTER OF THE 25 METER ZERO TARGET

  29. ZEROINGAN/PAQ-4A CONT 11. ROTATE THE BORESIGHT IN THE BARREL. IF THE SPOT DOES NOT MOVE OFF THE BLACK SILHOUETTE IN THE CENTER OF THE ZEROING TARGET, SKIP TO STEP 12 . IF THE BEAM TRACES A CICLE LARGER THAN THE BLACK SILHOUETTE ON THE TARGET WHILE ROTATING THE BORESIGHT , THEN THE FOLLOWING ADJUSTMENT MUST BE MADE.

  30. ZEROINGAN/PAQ-4A CONT HOLD THE BORESIGHT IN THE BARREL WITH THE MOUNTING FOOT IN THE 12 O’CLOCK POSTION. ROTATE THE BORESIGHT ½ TRUN TO THE 6 O’CLOCK POSTION. OBSERVE THE MOVEMENT OF THE SPOT BEFORE AND AFTER ROTATING THE BORESIGHT. ROTATE THE AZIMUTH AND ELEVATION KNOBS IN ACCORDANCE WITH THE FOLLOWING CHART:

  31. ZEROINGAN/PAQ-4A CONT MOVEMENT OF SPOT DIRECTION OF ADJUSTMENT ROTATION AZIMUTH ELEVATION

  32. ZEROINGAN/PAQ-4A CONT NOTE THE RATE OF ADJUSTMENT IS ONE SQUARE(1/4 INCH) PER CLICK AT 25 METERS. THE NUMBER OF CLICKS ROTATED SHOULD BE HALF THE TOTAL DISTANCE THE SPOT MOVED IN EACH DIRECTION WHEN THE BORESIGHT WAS ROTATED ½ TURN

  33. ZEROINGAN/PAQ-4A CONT EXAMPLE IF THE SPOT MOVES 8 SQUARES TO THE RIGHT AND 8 SQUARES DOWN WHEN THE BORESIGHT WAS ROTATED THE FOLLOWING ADJUSTMENT SHOULD BE MADE

  34. ZEROINGAN/PAQ-4A CONT ROTATE THE AZIMUTH KNOB 4 CLICKS ROTATE THE ELEVATION KNOB 4 CLICKS REPEAT STEPS 11 UNITL THE SPOT NO LONDER MOVERS OFF THE BLACK SILHOUETTE WHEN THE BORESIGHT IS ROTATED ½ TURN

  35. ZEROINGAN/PAQ-4A CONT • WITH THE RIFLE MOUNTED SO THAT THE BORESIGHT SPOT IS ON THE CENTER OF THE TARGET, SWITCH ON THE MOUNTED AIMING LIGHT • USE THE ADJUSTER KNOBS TO ADJUST THE MOUNTED AIMING LIGHT SPOTS UNITL IT LIES AT THE 10 O’CLOCK AND TOUCHING THE BORESIGHT SPOT

  36. ZEROINGAN/PAQ-4A CONT MOUNTED AMING LIGHT BORESIGHT SPOT

  37. ZEROINGAN/PAQ-4A CONT • REMOVE THE BORESIGHT FROM THE BARREL. • ZERO IS COMPLETE

  38. CONFIRMING ZEROAN/PAQ-4A • FROM A SUPPROT POSTIONS, SWITCH ON THE AIMING LIGHT AND POSTION THE SPOT IN THE CENTER OF A 25 METER ZERO TARGET. • FIRE A 3 ROUND SHOT GROUP WITH THE SPOT CENTER MASS OF TARGET.

  39. CONFIRMING ZEROAN/PAQ-4A 3. WALK DOWN TO THE TARGET AND INSPECT THE SHOT GROUP FIRED. IF 2 OUT OF 3 ROUNDS ARE WITH IN THE DESIGNATED STRIKE ZONE, SHIP TO STEP 4. IF NOT DETERMINE THE NUMBER OF CLICKS REQUIRED TO MOVE THE CENTER O FHTE SHOT GROUP TO THE DESIGNATED STRIKE POINT. REPEAT STEPS 1-3 UNITL TWO OF THE THREE ROUNDS ARE IN THE DESIGNATED STRIKE ZONE.

  40. CONFIRMING ZEROAN/PAQ-4A 4. THE AIMING LIGHT IS NOW ZEROED FOR 100 METERS. REMOVE THE OPTICAL RETAINER AND REPLACE IT WITH THE SCATTER SHIELD. NOW THE AMING LIGHT IS READY FOR OPERATION.

  41. EMPOLYMENTAN/PAQ-4A • MOUNT • NIGHT OPERATIONS • SPOTTING
