ANTI CHOP EYES/BALL DETENTS
MAINTENANCE AND CHANGING
When re-assembling the eye pipe assembly, work backwards from disassembly. The eye pipe is
keyed into the breech and can only go in one way.
CHANGING BALL DETENTS
The ball detent system is clipped
to the outside of the eye pipe. The
ball detent system needs little or no
maintenance. The detents should
easily flex out of the way with little
force, such as a paintball moving
past. If you are experiencing double
feeding or chopping, check the
condition of your ball detents with
your finger to make sure they are
not broken and that they move
in and out of the breech freely. If
excessive broken paint or dirt has
jammed your ball detents, remove
the eye pipe/detent system from
the front of the NT11 and unclip the
detents for a thorough cleaning.
Reinstall the detents and eye pipe
after you have sufficiently cleaned
the detents and breech.
Be careful not to over-flex the detents when handling them. Excessive flexing could break or
damage the detents.
NOTE: Take care when replacing the eye pipe. Be careful that the detent clip is fully seated
onto the eye pipe

ANTI CHOP EYES/BALL DETENTS
MAINTENANCE AND CHANGING
ANTI CHOP EYES
The Anti Chop Eye (ACE) system will prevent the NT11 from chopping paint by not allowing the
marker to fire until a ball is fully seated in front of the bolt. The eyes use a light beam across the
breech. On one side there is a transmitter, and on the opposite side a receiver. In order for the
marker to fire with the eyes turned on, the signal between the two eyes must be broken. After
every shot, before the next ball drops in the breech, the eye transmitter and receiver must see
each other. If there is a malfunction, the LED’s on the board will start blinking green. This means
that the receiver and the emitter do not see each other. If this is the case, there are normally two
reasons. Either there is dirt, paint or grease blocking the beam, or the battery is so low there is
not enough power to create a strong enough light beam.
NOTE: If the battery is low, the marker may act as if the eyes are dirty or not fire at all. In this
case, replace the battery.
SELF CLEANING EYE FEATURE
The NT11 is equipped with a self cleaning eye feature. There is a clear poly-carbonate sleeve
mounted inside the breech of the gun covering the eyes. When the bolt tip O-ring passes
through the eye pipe, it sweeps off any dirt, grease or paint that could be blocking the eyes. Nor-
mally, it is enough to just fire the NT11 to clean anything blocking the eyes. If this does not clear
the blockage, use a swab to clean the inside of the breech.
For a more thorough cleaning, pull the eye pipe with the ball detents out the front of the breech.
With the eye pipe out, use a clean swab to clean the breech. This should be enough to clean the
eye system. If the system needs further cleaning, pull out the eye carrier and eye wires through
the feed neck. To prevent damaging the eye wires, it is best to remove the frame and disconnect
the eye wires from the board. Use a soft rag and q-tips to clean off any built up paint or grease.
