Adjusng velocity
Use a 1/8” allen key to adjust velocity as shown.
The arrow on the diagram is an clockwise, which
is increasing velocity. Always use a chronograph,
and use small adjustments.
Adjusng the trigger
Your trigger has four adjustment screws, they are located in the front face
of the trigger and also on the upper face. In order of top to boom, they
are the trigger rest point, spring tension, actuaon point and stop point.
You can easily adjust these screws to personalise the feel of your trigger.
DO NOT ADJUST YOUR VELOCITY
ABOVE 300FPS, AND ALWAYS OBEY
LOCAL LAWS AND REQUIREMENTS.
CAUTION! WHEN ADJUSTING THE SWITCH ACTUATION SCREW, MAKE
CERTAIN THAT YOU DO NOT ADJUST THE SCREW IN TOO FAR, AS THIS
MAY RESULT IN DAMAGE TO YOUR MICROSWITCH.

ADVANCED SETUP
Tourney lock
The marker board is equipped with a tourney lock system. When the
tourney lock system is acvated, the marker cannot be reprogrammed
on the eld - making it tournament legal.
If your board is in locked mode, you can view your sengs, but a
lock indicator will be shown on the right hand side of the screen,
indicang that your board will need to be unlocked before sengs
may be changed.
The lock status can be changed by opening the le hand side of the
marker wrap around grip to gain access to the circuit board. The
tournament lock is a black buon. Press and hold the tourney lock
buon unl an on screen indicaon of tourney lock status is shown.
lock buon
Entering program mode
To program the board, hold down the trigger whilst turning the marker on. When done correctly, you will see a message
on your display screen indicang that programming mode is loading. You must connue to hold the trigger unl the
program mode is loaded, then release the trigger.
Finding and changing sengs
Once in program mode, the OLED display will show a current seng. you can advance to the next seng by tapping
the scroll buon ( ). You can go back to the previous seng by tapping the power buon ( ).
12

Once you have found a seng you would like to change, press and hold the trigger unl the seng changes to red.
The seng can now be changed by tapping the scroll buon to increase its value (or change to a dierent opon), or
tapping the power buon to decrease its value.
Once you have adjusted the seng to a value you would like, press and hold the trigger again unl the seng returns to
white colour, it has now been saved.
If your tourney lock is on, sengs that can change the tournament legality of your marker will be locked. Their seng
can be viewed, but not changed. You will know if the tournament lock is blocking eding, because a red lock symbol will
show in the upper le hand corner of the screen, and the seng will not change to the usual red colour. If you would like
to change a locked seng, you must open the wrap around grip and hold in the tourney lock buon. This may be done
inside program or normal running mode.
Sengs in detail
Mode - The type of ring system used, semi auto, Millenium and PSP are common tournament modes. Ramp mode
allows the programming of custom ramping behaviour.
ROF - This is the maximum rate of re allowed by the marker. This seng is only observed if the nex seng, rate of re
cap is set on.
ROF cap - If the cap is enabled, the marker will be limited to the ROF seng. Otherwise, it will re as fast as the laws
of physics (and paint supply) will allow.
Dwell - the amount of me your solenoid is given power - the Prime should be set to a maximum of 12ms. If the
weather is very cold, or your marker requires it, you may set this a lile higher.
Debounce - the amount of bounce ltering applied by the soware. This seng may be increased to remove unwanted
trigger bounce.
Ball delay - this is a parameter used to give a paintball me to sele in the breach of the gun. If you have unexplained
ball breakage, then you may need to increase this seng.

Eye sensivity - the sensivity of the soware to changes in your eyes. Please do not change this parameter unless
directed (default 10).
Forced shot - when enabled, this will allow the user to force a shot by holding the trigger in - even if the eyes cannot
detect a ball. Set this to o, if you would not like to use this funcon.
FSDO me - FSDO stands for First Shot Drop O. If you leave your gun for some me, and the rst shot is lower than
it should be, then you can use this parameter to correct it. This parameter is the me that the soware waits before
correcng for FSDO.
FSDO dwell - this is the amount of extra dwell given to the solenoid to overcome FSDO - if directed to do so by the
above parameter.
Ramp semishots - this seng (and the other three below) is only used if you are using the Ramp remode. This is the
number of semi auto shots which must be red before ramping is allowed.
Ramp rate - this is the number of shots per trigger pull when in ramp mode.
Ramp ROF - this is the rate of re which must be achieved and maintained to stay in ramp mode.
Ramp meout - the amount of me the user can spend below the ramp ROF before ramping is exited.
Sound - turn sounds on or o.
Auto power o - save power by automacally turning the marker o aer 30 minutes.
Load/Save proles - Your marker has two prole save slots. Once you have your marker set up as you like it, go to
save prole and select one of the proles. Hold the trigger in on the prole number you would like, and the current
sengs will be save to that prole slot. You can reload them at any me using the load prole opon.
There is an opon under load prole, to load factory defaults.
Version informaon and shot counter is shown on the nal seng screen.

sengs changes.
Changing the front grip angle
Your Prime XTS front grip can be used ina an 8 degree or vercal
posion. It is shipped in the 8 degree posion. To change it to vercal,
remove the frame completely, and follow these steps:
Remove the cap using
your allen key
Slide the grip

MAINTENANCE
If you take 10 minutes aer every day of play to maintain your marker, you will be rewarded with consistent reliable
performance.
You should perform basic cleaning aer every day of play, and you should perform drivetrain maintenance every
5 cases. You should perform inline regulator maintenance every 20 cases. You can clean and maintain your marker
more oen, it is up to you.
When maintaining your marker, use only MacDev accessories. Your marker is packaged with an allen key set and a
small tube of MacDev Milia Lube, only use Milia Lube for lubricaon.
Basic cleaning
Aer using your marker, always clean old paint from the outside. Always clean your barrel using a barrel swab to
remove traces of dirt and paint. Use your barrel swab to clean the breech and feed tube in a similar way.
Your marker internal parts are quite well protected and sealed. However, when not in use, dirt can get into the
marker and cause problems - so storage of your marker is just as important as cleaning. When storing your marker,
ensure that it is stored a bag that is free of dirt, otherwise dirt may get into the venng ASA or breech.
16

Maintaining the drivetrain (every 10,000 shots)
To maintain your drive, ensure your marker is fully degassed and pull the drive cover up
to release the drive. Slide the drive out of your Prime. Unscrew the drive parts to access
the components shown in the diagram below.
Clean the old grease and dirt from the keg, bolt and valve. Apply fresh Milia Lube to the
keg inner o-rings (#17 and #19). Apply fresh lube to the #M16-2 o-ring on the bolt, as well
as the inside of the larger end of the bolt. Slide the bolt back into the keg. Apply fresh
lube to the #14 o-ring on the valve and slide it into the bolt, then screw the valve into
place. Complete the drive assembly by screwing the valve cap back onto the valve.Lightly regrease the outside of the
drive and slide it back into your Prime marker.
More detailed drawings of the sub assemblies are available from macdevpaintball.com/support.

Maintaining the inline regulator
(40,000 shots)
Before working on your inline reg, make certain that
the air supply is turned o (via the venng ASA), and
safely re any gas out of the gun to ensure it does not
have any residual pressure.
To access the regulator, remove the le hand side of your wrap around grip. This will allow you to unscrew the body of
the regulator.
Clean the inside of the frame bore with a q-p, and remove old grease from the regulator piston. Apply new grease to
the piston sha, and the #11 o-ring on the piston, as well as the #8 o-ring.
Apply new grease to the inside of the frame bore before re-installing your regulator.
More detailed drawings of the sub assemblies are available from macdevpaintball.com/support.

Unscrew regulator from frame
(degass marker rst)
The piston may not come out with the regulator
body. Never use pliers or any tool to grab the piston,
this can damage it. Use a 1/8” allen key pushed into
the centre hole of the allen key to help remove the
piston if it is lodged in the frame bore.
