Airforce Texan Bottle keeps Loosening up , Set Screw no More?

[Shooting Targets]

So got my airforce texan .257. Put on the bottle with the special made tool. After a short while the bottle came loose wiggly back and forth. I took the special twisty tool to it again but it keeps coming kind of loose. So there is a mention of a set screw that looks like it has the ability to be screwed in. I do not see a set screw but more like a hole where a screw could be used to finally set the airfoce tank in ?

So my question is there a set screw on the texans or only the wrench to be used. I am cranking on this pretty hard to make it set and stay set??

I haven't worked on a Texan but I'm confused as to how it can loosen. No bottle threaded in and pressurizing the gun can loosen on its own. The loading on the threads from the pressure prevents it from moving.

I set the nut and index it so the bottle needs another 1/12'th of a rev and tightens the bottle. Dont use the tool at all.

My .50 cal has stayed put for the past 400+ shots.

Yea, I am confused. There older condor you would just rotate and screw in the bottle into the frame and I thought but cannot remember if there was another hex nut that would finally screw it in to make sure the bottle/butt of the gun would not come loose. From what I see I have this wrench, I use on the texan and indeed you rotate the wrench to bring the bottle into the frame. It is a slow process but is this the only process to secure the tank ?

The instructions say use the wrench , ok got that. Then there is a SET SCREW below that the instructions mildly mention which does not even look like it is available. There is a hole but not really available with any screw to tighten. So i guess my question to texan uses is the wrench the only thing you need to tighten the bottle into the frame ? Did you do anything with a set screw or any other screws to get the bottle firmly installed ?

ChickenThief. You make it sound like you have have a nut/set screw to do the final tightening of the bottle into the frame ?? I am turning the large wrench piece pretty hard do not want to break or strip anything. Just want to make sure if putting on the bottle is a 1 step or 2 step process and I am missing step 2 ??

The same setup as you but i have the bottle turned with the pressure gauge slightly downward. Seen from behind the bottle is slightly turned counter clockwise.

I fingertighten the nut from the front with my fingers and turn clockwise/tighten the bottle for the final amount.

Might take a try or two but you'll get the hang of it fast.

Just dragged mine out and there is indeed a threaded hole for a grub screw. But beware there is very little material there and stripping the thread would be easy.

The best cure for frame flex in Air force guns that cause the bottle to come loose is a good support system. The Maddog stock is the answer.
