My MP5SD can is a pain to get broken down after its been used a bit

My current methods of beating them out is kind of worrisome that I will eventually damage the tube.

I have never been one who could envision tool design so I was hoping someone smarter than me has already came up with an idea.

Something with a threaded rod that would start to pull out the baffles as you spun a nut or something would be awesome

Right now my best way of extraction is using a long screw driver that has a plastic handle. I use the handle end on the baffles and bang away on the metal end with a hammer. They just dont ever want to come out easily

Large diameter wooden dowel and a hammer

Yeah the only problem with this and the way I do it is once a baffle gets to the end of the tube its hard to get it to continue to come out if you have the end say on wood and driving the dowel downward

There looks to be a .22 to 30 cal one on the market

But notta for pistol cal. Banish is the maker?

I suppose using the same idea as that I could just do something like the below

Spinning the nut on the right should move everything on the left in and thus pulling the baffles or whatever out

That's how I bent the lip of my AAC Aviator 2, much better to buy/make a tool for the job.

Is there a reason the AAC baffle removal tool design couldn't simply be scaled up, perhaps ECCO Machine or Curtis Tactical could give it a go?

I made something years ago like the thing you have pictured (for my TAC65) but I just used washers on both ends, one that fit just inside the ID of the tube and a fender washer at the other end.  Works much better than trying to beat them out IMO.  Still a good idea to soak it a little ahead of time to lube everything up.  Once you get them broken free and moving, it comes apart pretty easily.
