I know this has been addressed on here before, but I cannot find any of the posts. We have a patriot 425, when using the crank cocker that's mounted to the buffer tube, it bends the tube way up.... what are the fixes for this?

Any and all information is appreciated

Are you collapsing the butt stock before using the crank cocking device?
Collapsing it will increase the strength of the tube. The main tube has a
very thin wall thickness.
1)possibly where the crank device mounts is not centered on the tube
but a bit lower which will add stress to the angle when cocking.
2)one could go to the crank cocking device where the bracket fastens to
tube of the butt stock near the back of the scope area. The disadvantage
is for a shorter arm person, the butt stock will not fully collapse.

I have two Center Point Sniper XT390 where I modified the butt end of the
stock to accept the plug in crank cocking device like some rebranded Rocky
Mountain crossbows use. Mine will center in the tube and when cocking, the
butt stock is fully collapsed.
Note: there is a difference in the way the butt end of the stock is designed
between these two series of crossbows so the plug in may not work for yours
due to the different shape of the butt end unless you could modify it.

As Joe PA mentions, adding a re enforcement may help. If the PVC is the
wrong diameter, check with a muffler shop as they have different sizes of
exhaust pipe. Another option is finding a pipe slightly over size and lathing
it down to fit.

Wishing you all the best.
Take care.

It is not the actual tube bending, the molded stock has a plastic ring that the tube sits on ......when pressure is applied the ring crumbles allowing the tube to bend forward . It is a manufacture's defect.

Biggest POS I've ever owned. First was the tube let go when using the power crank ER almost lost a finger. After putting a nut and bolt in to resolve the screw coming loose problem. I was shooting again and the draw string exploded breaking the same finger again. Crossbow under $400 ER over $5,000 do the math dumpster food.

That's surprising!!! I've been reading all the problems with the Centerpoints and I have a Patriot 415 which had the same problem and they won't warranty it because they said I was cranking it wrong which caused the tube to rise up. The thing about this is...I just started sighting it in and not strong enough to use a rope cocker.

The narrower axle to axle high draw weight crossbows take a lot of power to cock them.
A wider axle to axle crossbow with the same draw weight limbs cocks easier due to having
more leverage.
When a cranking device is mounted on top of the tubing, this places a lot of leverage on
the tube of the stock. To prevent this, the butt end of the stock should be modified to
accept a plug in crank cocking device which then has direct inline pressure.

To do this on a crossbow like the Patriot 415, remove the butt pad and shape two pieces
of 3/4" oak equals 1 1/2" thick with a + to accept the plug in crank cocking device like some
of the rebranded Rocky Mountain crossbows use. Picture of the crank cocking device like
this one. The blue handle one is what Carbon Express Pile Driver came with. The orange
handle one is the Rocky Mountain style which is a better design as it has a small spring loaded
ball at the bottom of the handle. Adjusting the small Allen screw increases pressure if one wants
to leave the handle on the device. Handle can be used on either end of the drum shaft. If one's
hand came off the handle when cranking, there is no danger of a back spin or dry fire. I have
modified all my crossbows to accept this device.

With this style device one does not require the sled like is required when rope cocking, but
just the hooks. The nice part about the design of these shown devices is the crank cord is
all enclosed so less chance of a tangle up.

Wishing you all the best.
Take care.

As per Post #15, modify the butt stock to accept a crank cocking device that plugs
into the back of the butt stock. This eliminates the problem of the tube bending.
With the 200 pound draw weight of the crossbow and more so if the cams are
advanced, Center Points crank cocking device puts a lot of leverage on that thin
tubing because the device is mounted on top.

Wishing you all the best.
Take care.

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.
