HDD for QB-7X ???
« on: May 09, 2010, 01:49:40 AM »


Does / has anyone made a hammer debounce device (HDD) for the QB-7X guns? From what I've read a HDD really helps with shot count in the 22XX Crosmans.



I haven't even received my QB yet and already thinkin' 'bout mods!

Never heard of it used in a QB. Anyways, you should be concerned w/ power mods ...LOL. Congrats on your new purchase. The QB78 was one gun, if not THE gun that got me into this mess..

And by the guns you have listed the QB could be the most powerful.

Have fun w/ the new QB and keep us updated.

A picture of Scott's (?) QB should be attached.
You might try low tech by using a felt pad with a hole in the middle to the rear of the valve body.
