Mods, if this thread is in the wrong forum please move it to the correct one...
I got this rifle about a year ago, I shot it enough to tell that it is probably clipping..I don't think I could hit a paper plate at 50ft range.
I am not the best shot in the world but I am pretty sure it's not human error. .
I loosened the two grub screws(is that the correct term?) and it doesn't want to move at all. I am no 90 pound weakling but I am unable to twist any movement into at all.
I am assuming that the previous owner glued it onto the barrel.
When I look into the business end, with a light shining into the open bolt I can tell it's crooked. I do not see any evidence of damage to the TKO but something is wacky, it's throwing pellets everywhere. .
Is there a way to take the TKO apart? I would rather not destroy it, I just want it off.
I am wanting to make a shorter barreled QB78, but as a separate project, I don't really want to cut this barrel until I find out how it shoots.
I do have a heat gun, I can get it hot. Will doing that be detrimental to the TKO?..
Any suggestions on a course of action?
Thanks in advance for your time and troubles in helping me out. .
One of three things happened.
Could be that the set screws are spinning rather than actually turning out (they do tend to strip if you over tighten them).
Could be that it was jammed onto the end of the barrel deeper than it was designed for (they really aren't supoose to be jammed on until they hit the 1st baffle as a "stop").
Or (and likely are right about this) it's glued on.
Assuming it is glued.
Be sure the little set screws are not just loose, but OUT.
Heat the barrel about 2" back from the end of the muzzle brake (far enough back that a propane torch flam wont directly hit the TKO).
Can wrap a wet rag aroung the barrel 3" back if worried about heat transfer.
Pull and rotate the TKO while the barrel heats.
If you are careful, the glue will let go before the TKO gets over heated/melts. If he used really good slow cure epoxy (like JB Weld steel) may be hosed.
