Trying to fix a leak, gun has been sitting for a few years. Attempted to unscrew the charging handle, only to find out it was just a brass piece red lock tited over an already broken shaft. Doesn't want to unscrew. Tried heat, penetrating oil, right now I have a soldering iron on top of the broken bolt. If worst comes to worst I'm going to cut it off so I can remove it to access the valve. Anyone recognize the charging handle block? If I cut it I may have to find a replacement. It's .45 cal if you're wondering.

Any more information on what it could be or is based off of? I can't pull any ideas from the Pics. If it was my project I would cut off the remnants and drill it out carefully to try and discover threads, or just make parts.... That's just my brute force method for crosmans in this pickle.

I can see that the bolt goes all the way through. Im going to let it sit over night and see if I can get it to come out. If that don't work I'm going to cut the shaft off as close as possible so I can to the rest of the gun.
Thanks. FYI- Not sure what it's cobbled from?

That looks like a QB 78 or an ARplatform. From what I remember there’s an Allen key bolt threaded into the hammer that keeps it in the position. Did you by chance take that out already?

Yes, that bolt is already out. This charging handle goes all the way through. I think who ever assembled it used red loc tite. Then when it broke they used a brass cover red loc tited to the end of the broken shaft. I'm going to let it sit overnight with penetrating oil and try again tomorrow. If it still doesn't budge I'll cut it off with a Dremel so I can at least pull it out to access the valve.

The amount of heat needed would be too much for the level of assembly you're at, I fear. They recommend loctite chisel to remove it. It's methylene chloride and methanol with butane propellant. I know the automotive product Heet is a source of methanol, and Kutzit paint stripper has the methylene chloride if you can't find the loctite chisel stuff. My usual go-to when kroil doesn't work is acetone and automatic transmission fluid mixed together. I'd try super cooling it too to make it move. Liquid co2 or upside down keyboard cleaner can do it. If you're really angry acetone and dry ice can get dangerously cold.

Sorry this is way out into mad scientist territory.

I actually got lucky I used liquid wrench and let it sit for a day. I was able to get it unscrewed with some vice grips.

Just dug it out ... had one similar come threw the shop last month. Still here & not worth my shop time and labor to "Un-Screw" it up. Sadly a pile of parts for owner.
It too loc-tited together, barrel held in with JB weld type epoxy .... clean gun overall but a platform that was never designed to be what some well intending AG tech made them into :sneaky:
This one a .30 cal
Internals .. No clue.

Too bad. The other one I have (.177) was made by RichInMich. I'm in the process of replacing an oring or 2. That will be for my better half😁
