hi , going to buy a set of hex keys am I right that the crosman will be metric ???
The machine screws on 13XX and 22XX family air pistols are SAE threads.
The tiny hex head of the breech/receiver mounting screw is not found in most of the cheaper hex wrench sets. Be sure to look for it before you buy.
Also I found that the small ball head hex wrench doesn't work well at all, the head of the breech screw is too shallow, I had to grind the ball tip off before it would grip well enough to turn the screw.
If you plan to do much work on these order a slot head breech screw.
thanks , for your quick response I will get a couple o the slot head screw regards "ken
I've always had good results using a T05 Torx bit on the breech screw without doing the flat head screw thing... I have this thing against slotted screws, they are a last resort...
bought my self a good set which fit all thanks. 'ken
