I am currently machining another batch of barrels. I hope to have them ready to ship by the end of next week. This will cover everyone with a barrel on back order. Have a safe holiday.
Do you ever do 40 s&w barrels?(what is cost?, can I use my 9m bolt or need a new one?I am currently machining another batch of barrels. I hope to have them ready to ship by the end of next week. This will cover everyone with a barrel on back order. Have a safe holiday.
I have not made any .40 S&W barrels at this point. You would have to have a bolt made for .40 S&W a 9mm bolt face it too small and a .45 ACP bolt face is too large. The next problem is what do you do about a reliable magazine for the Uzi.
You would first have to get a barrel made with the proper bore. The 9mm Makarov bore is .010" larger then a 9X19 bore. The bolt face would be fine. The Makarov is about 1/8" shorter then the 9X19 so you would probably need to install a spacer in the magazine. I don't know if the 9mm Makarov has enough power to cycle the bolt reliably. I do not see any advantage in using the Makarov instead of the 9x19. You would have about $500 into a custom barrel.
Well if you want I am more than happy to insult you.
