THE "REX" VELOCITY ADJUSTER KIT

 

CONGRATULATIONS ON PURCHASING THE "REX" WORM-DRIVE VELOCITY ADJUSTER KIT FOR THE AUTOCOCKER, THIS QUALITY PRODUCT WILL BRING YOU MANY BENEFITS:

 

1/ YOU CAN ADJUST THE VELOCITY OF YOUR GUN WITHOUT REMOVING THE COCKING ROD, ALTHOUGH YOU MUST REMOVE THE ALLEN WRENCH WHILST TEST-FIRING.

2/ UTILISES A LIGHT SPRING SYSTEM FOR SMOOTH COCKING ACTION (ALSO MEANS THE COCKING PRESSURE CAN BE REDUCED TO GIVE ENHANCED OPERATION).

3/ TOP ADJUSTER COMPATIBLE FOR EASE OF TIMING ADJUSTMENTS (ON OLDER GUNS IT NEEDS ONE HOLE TO BE DRILLED IN BODY)

 

INSTALLATION

 

WE RECOMMEND THAT YOU HAVE YOUR "REX" KIT INSTALLED BY A PROFESSIONAL AIRSMITH, HOWEVER, IF YOU WISH TO FIT IT YOURSELF THERE ARE A FEW POINTS TO BE AWARE OF:

A/ SIMPLY DROP IN YOUR NEW REX HAMMER THEN THE MAINSPRING FOLLOWED BY THE REX ADJUSTER. YOU WILL NOTE THAT ON OLDER GUNS THIS PRECEDURE IS EASY BUT SINCE THE ADVENT OF BODIES WITH THREADED LOWER BORES IT IS A LITTLE MORE DIFFICULT. IF YOU HAVE THE LATER YOU WILL HAVE TO DRILL OUT THE REAR MOST THREADS (PREVIOUSLY USED TO ATTACH YOUR BEAVERTAIL TOO) WITH A 3/16 INCH DRILL AND USE THE SCREW AND WASHER PROVIDED TO ATTACH YOUR BEAVERTAIL (PUTTING THE SCREW RIGHT THROUGH THE BEAVERTAIL THE THREAD YOU'VE JUST REMOVED AND INTO THE THREAD OF THE REX ADJUSTER) THEN CLAMP IT TIGHTLY TOGETHER.

(NB PLEASE BE CAREFUL TO DRILL OUT THE CORRECT THREADED HOLE AS THEY LOOK THE SAME, IT IS THE REAR MOST ONE YOU ARE AFTER)

B/ TRY TO USE THE LIGHTER OF THE THREE SPRINGS SUPPLIED IF POSSIBLE.

C/ ALWAYS USE YOUR GUN WITH EITHER A REGULATED CO2 SYSTEM,A DOUBLE-REGULATED AIR/N2 SYSTEM OR A BALANCED AIR SYSTEM. THE RECOMMENDED INPUT PRESSURE TO THE GUN IS DEPENDENT ON YOUR PREFERRED SET-UP BUT GENERALLY IT SHOULD BE BETWEEN 200 AND 350 PSI. FAILURE TO USE A REGULATED SYSTEM OR THE WRONG PRESSURE WILL RESULT IN EXTREME VELOCITY SWINGS.

D/ TO ACCESS THE VELOCITY ADJUSTING SCREW A HOLE NEEDS TO BE DRILLED IN THE REAR BLOCK, AGAIN WE RECOMMEND THIS IS DONE BY A PROFESSIONAL. THE SIZE AND POSITION OF THE HOLE IS AS FOLLOWS:

 

 

USE/MAINTENANCE

 

TO INCREASE VELOCITY INSERT A 3/32 INCH ALLEN WRENCH IN THE ADJUSTER SCREW AND TURN ANTI-CLOCKWISE, TO DECREASE TURN CLOCKWISE.

 

************PLEASE NOTE THAT THIS IS THE REVERSE OF A STANDARD GUN************

 

LUBRICATE OCCAISIONALLY BY SMEARING A LITTLE VASELINE ON THE WORM SCREW AND  SPRING FOLLOWER, WHEN REASSEMBLING PUT THE WORM AND FOLLOWER IN TOGETHER WITH THE FOLLOWER OVERLAPPING THE WORM O-RING.

WARNING- IF YOU TRY TO INSTALL THE FOLLOWER WITH THE WORM IN POSITION AND DIAL THE FOLLOWER ONTO THE WORM THE WORM O-RING WILL BE DAMAGED.

THIS O-RING IS A FRICTION DEVICE TO PREVENT VIBRATION AFFECTING THE VELOCITY ADJUSTMENT, IF IT NEEDS REPLACING AND YOU CANNOT GET A SPARE THEN AN AUTOCOCKER 3-WAY SHAFT O-RING WILL WORK.
