(Do not use the springless bolt handles with a housing designed for
the spring loaded bolt handles and vice versa.)
The next step in the CCU disassembly is to remove a total of 8
SHCS’s - 4 on each side of the housing at the front. The heads of
these 8 screws also serve to locate the plastic foregrip. You will
need a 9/64” hex wrench. The screws are 8-32 SHCS’s which are
5/16” long.
Do not substitute screws of a different length. If one of
these screws is lost, you can make one from a longer screw of the
same kind, but be very careful to finish with the same thread
length as the original.
With the bolt cocking handle and the 8 screws removed, the
bolt/barrel subassemblies may be withdrawn from the main housing
by pulling forward gently on the barrel. Now things can get tricky.
The only thing causing the bolt to follow the barrel forward is the
recoil spring. If the CCU has been functioning properly, the bolt
moves freely within the housing. If you ran over the CCU with your
pickup that will not be the case. If the bolt is stuck it will have to be
driven out of the main housing using a short length of wooden
dowel, one end pressing against the rear of the bolt while tapping
the other end with a mallet.
In this case the bolt will move the barrel out of the housing. Back to
the normal way. As the bolt/barrel subassemblies are withdrawn
from the main housing, the junction between the bolt and the
barrel support will become visible (see FIG.6). Continue the with-
drawal until about 3 inches of the bolt is showing. At this point
change your grip such that the hand which was pulling on the barrel
now grips the two assemblies right over or slightly to the rear of the
junction and then continue to withdraw until everything clears the
housing. Set down the housing while maintaining a solid grip on the
bolt/barrel subassemblies. Don’t loose control or the bolt and barrel
subassemblies will part company, the recoil spring will suffer dam-
age, and stuff will fly all over the place!
With the housing set down, both hands are free to deal with the
bolt/barrel subassemblies. If you are right handed, the bolt/barrel
subassemblies will be in your right hand with the barrel pointing to
the right. Use your left hand to firmly grip the rear 3 inches of the
bolt, trapping the recoil spring under the palm. Work the right hand
position slowly toward the muzzle while maintaining the fingers
wrapped around the barrel support (FIG.6). Maneauver the right
hand such that the right thumb is pressing against the top of the
recoil spring retaining post on the barrel support.
