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?

You have joined a worldwide club when it comes to that detent ball and believe me the spring can be just as elusive. It will be interesting whether the breech screw remains the same now the Crosman's are being manufactured in China.

Hi Kris.

You can get both from Young's Airgun Centre.  Give Ron a call, he is a super guy to deal with.


Spoke with Ron this AM, he's waiting on some.

Thanks
