DM 11 Velocity Adjustment Screw Stripped

Hey all,

So I got a used DM11 in trade yesterday, tore it apart to clean and lube and ran into trouble with the Hyper 3.

First off, the reg was impossible to take apart. I had to wrap in hockey tape and then use a vice grip to take the parts apart. After cleaning and lubing everything, I put it back together and all seemed fine.

(I did not check to see if the adjustment screw operated correctly before I got my hands on it)

I went to set the hpr to 0 before gassing the marker up to check for leaks, and could not get the adjustment screw to move vertically up or down. At first I thought I couldnt find the right allen key, but it seems to just be spinning as I turn it.

I dont know how I would have stripped it, and it appears that the threads are stripped not the top of the screw (the allen key fits in nicely) I also would have thought that if I somehow stipped the threads, the screw would simply fall out.

Any suggestions? How do I get it out? Is there a replacement at a local hardware store I can buy (if I can get it out)

Has this happened to anyone before?

Are you sure you have it installed properly? Push in as you turn. If that doesn't work take it apart again and inspect the threads.

It's a cheap replacement, I've got a couple of them sitting around. I've just never seen a stripped one before.
