These are all the fixator pins used in KPVT barrel!And also the unscrewed muzzle end nut!
By the way extremely hard to pull out!And unscrewing of all those nuts and mounts(5 in total)is just a nightmare!If you will need to provide the same kind of operations with such a barrel-just use the most powerful and unbreakable tools in existence,because especially the nut,situated at the rear end around the chamber is the hardest thing to remove that I ever encountered in my whole life!*
*by the way I once had to help some guy to fix his 45mm anti-tank cannon and there were no such a tough stuff to make even though it was excavated,and my KPVT barrel is obviously not!So my last hope is my friend's hydraulic press,which I will use as the force just to compress three wrenches,applied in the way so that compressing them will inevitably lead to unscrew of this monstrous extension!Just hope that my truck wrenches won't crack and that one thousand tones applied to the half metre shoulders of these wrenches will be enough!
