Potentially, but the tube isn't super thick. The good news....... This isn't the classifieds but I will say this. I'm a pack rat for mechanical bits and I have my trailnp22 main tube still, the nitro piston lost its charge and I hated the gun so I parted it out. It's just sitting in my office. Dm me if you think you'll want to rebuild yours and I can tell you about the other np bits.

the tube and mount will have a pattern left by the old glue so regluing it will be easy or should be
what the mount and tube needs is more surface area and with that more bite
now the mount is easy you need a 2mm drill and a drill press would be handy drill 1.5mm hole in the back of the mount alol over and then you will need to take a larger drill and chamfer those holes and you can do this by hand
now the tube you will need to mark out the mount area and with that 2mm drill make very swallow holes and not through the tube
glue epoxy
JB weld 82655 it is 24 hour sand it set slow so you have time to get it set and i will clean up with rubbing alcohol
now what is under that mount in the tube is unknown to me but if it is a void, pins would help to help the mount from come off from shear
pins could be simple rivets
now will it work and for how long, good question but in the case of mounts and shear heavy scopes should not be used
and i have heard of this problem before
that is the best i can do good luck
but the swallow holes drilled are the key clean surface will also be needed
good luck Mike

Many thanks but won't be rebuilding. I live in Zimbabwe so getting parts etc is more hassle than ehat it is worth

Oh! Yes that would be far more in shipping than it's worth. I would seek out a way to silver solder or braze that back on without distorting the tube. You'll need to remove the gas piston before applying heat. Good luck
