Alchemy breech

[crossliner]

On a 13xx air pistol the hidden-type breech screw breech would not work if the hammer does not have a "top canal".

It will hit the tip *(threaded part) of your breech screw when the hammer goes to battery.

You would also need to drill the tube since the 13xx tube has only 1 provision---the forward/visible location, that is.

This is a 2240 so I guess I'd be ok?

[crossliner]

Affirmative, senor.

The 22xx hammer has a notched top unlike the 13xx's.

Yeah I had to deal with the hammer issue when I put a Marauder trigger group in my 2260, all good fun stuff tho.

How about making a washer or two out of brass shim stock to bring the screw head up flush,
or even some aluminum from a pop can.
