I remember buying a few "driod" screw kits in from the UK that had better heads on them and suited their purpose much better. must have a look to see if I still have them.

FYI Fast trade in Hastings have a couple dozen 4-48 x 1/4 that'll fit the breech. They ain't cheap though, I've just ordered a couple, I'll tell you how it goes.

The small screw can be replaced with something else small enough, although you may need to retap the hole, which would need a threading tap. If you are going to play around with the 2240, maybe worth getting a small tap and die set, or you can buy individual taps from aliexpress.


The screw is a 4-48 x 1/4 I've since found out.

Oh no, so I'm guessing the breach screw won't be found at my local Blacks?
