Are you asking if the barrel has threads for an attachment?

I could not find a threaded barrel,

but I bought an extra barrel, rounded the front ~1/2 of the length and threaded it 3/8-24 for the extension below...

Once receive it this week, will add, machine to fit the profile of the slide opening and install.

there will be additional internal pressures in the cub until the bullet clears the barrel.........are you certain that there are no differences in the design of the camper and the cub to accommodate the addition of the barrel to the camper..?

maybe strength of materials are improved..?

FROM what i see, or hear, camper seems to only have a different barrel+ grips with the 'camper logo'.


Otherwise the rest seem identical. I wish somebody tried to exchange the barrels to let me know if that is so.

I also heard that some people have cycling issues with weaker .22 short less than 1050 f/s. I would think the camper with a bit longer barrel produces more back pressure to cycle more effectively with weaker loads.

Adding my ~ 1 " extension which is not rifled will hardly add any back pressure by itself, but depending what attached after that to the 1/2-28 end - is another story...but still , I believe safe for the action:

The gun is built of steel, seems very solid, tight, including the slide/bolt.
no unnecessary cuts on the face of the bolt that can give under 'explosion' of these puny loads.

I think I will be fine. Besides, bunch of successful and seemingly safe zip guns even for .22lr were made from much less superior materials- like plumbing brass.

I will keep you guys posted...

Also I plan to make an alternative Mag release in a regular , more usable position, just below the safety lever with minimum alteration of the frame. I would be happy to utilize the hole for the mag safety I had removed[very annoying]. it's right there in the correct position.

I'm surprised , i could not find on the internet somebody doing any of those modifications to the gun...

and Yes, yes it looses it's collection value, but i have no desire to ever sell this great toy...
