Question for Mag machinist.

[Badger1099]

So, last year I sold all my AutoMag gun and I have been missing them lately. I am now considering a pump Mag to give me my fix again. One of the thing I had that I let go was a left hand valve. They are a tough item to find again.

My question is shouldn't someone be able to tap out the other side? How hard would this be to do? How much would someone charge?

Thanks.
