The manufacture has added too much clearance between the outside diameter
of the tube and the collapsible section of the stock. One may be able to apply a
thin layer of tape to take up the slack.
Noticed in the submitted picture where the bracket is on the tube of the stock
to accept a crank cocking device. This is a very poor design. The tube is very
thin and with the cocking device on top several tubes have bent with damage
to the back of the scope. With this clamp installed, the butt stock can not be
fully collapsed when cocking the crossbow or for a shorter armed person.
Remove the butt plate and make one out of 3/4" oak with a + in it to accept a
plug in crank cocking device like the below submitted picture. This cocking
device is what is used on some of the rebranded Rocky Mountain crossbows.
The handle will fit either side. Where the handle fits onto the drum shaft, the
shaft has a groove for a spring loaded ball to fit. Adding a bit more pressure
by turning the small Allen screw in, one can leave the crank on the cocking
device. If ones hand came off the handle when cocking the crossbow, there
is no chance of a back spin resulting in a dry fire and no danger of a hand injury.
The Allen screw spring-ball is on the newer orange handle device.
The blue handle crank cocking device is the older version. I have both versions
and my crossbows are modified to accept them. Barnett Ghost series, I had
to use their sled as nearing the trigger box is wider and hooks jam up. Hooks
may come face up or down depending who assembled the device. Removing
one end of the cord and flipping the hooks over to the other position can be
done. Most hooks are riveted where as Barnett's sled hook system uses pins.
Wishing you all the best.
Take care.
