BNM breech screws missing Help!

[silent_airman]

I have an old BNM breech that I want to get back together, but I can't find the two screws that are used to attach it to the main tube, which is a 2250 tube. To compound the problem BNM is out of business. Does anyone know what size these screws are? It's the small one below the magazine and the one at the rear, which is bigger. Anyone have extras that they'd be willing to part with?

Breech under-the-probe screw should be 4-48, and the rear one should be 8-32; they’d most probably be cap screws but a button head could also work if your reduce the head.

Go to any Ace Hardware store and just bring the breech with you for length-sizing.

Thanks for the info!
