Does anyone know of a manufacturer making 3 lugs with non standard or custom interior threads?
I'm looking for 7/16x24 (I think) ETA: might be x20 Morgan at Class III machining says .470" OD |

Vz61 in 9mm Mak
I'm trying to plan out this project. I don't have the gun in hand - had to mail the gunbroker seller a money order 
Someone said the OD might be 12mm and someone else suggested threading 7/16 By all means, I'm open to other theories. I'd like to use my 3 lug can but if something like a custom rear mount on a Tirant is for some reason easier, I'm all ears. .530" at the muzzle |
| You have Howard's email address. Work with him to get a 3-lug muzzle device made, and he could do them in whatever thread pitch people needed. We started to fool around with it for the SWR Trident, but SRI claimed they were coming out with parts about the same time so he bailed on it. |

Yeah. This is why I couldn't get my Beretta 84 in .380 threaded.
7/16= .4375 Minus the .355 bore Leaves you with .0825. Not good. You need a meatier barrel. |

I picked up the gun earlier
It's 0.530" at the muzzle. Attached File |

You could install a Gemtech 1/2-36 male 3-Lug, which has a thread length of .900 back over the barrel. We are running 2 weeks in the shop right now. Hope this helps? Joey Quoted:

You could thread it M13.5x1LH an run standard metric pistol cans with a fixed barrel spacer. 13.5/25.4=.5314" |

Quoted:
Beware: Any practical pitch 7/16" threads will not have enough wall thickness for a .308 caliber barrel. If you could manage to thread it, the barrel would snap off on firing. 7/16x28 is what they are using from the factory. I have done some tokarev extensions in 7/16x20 and they have held up. Edit: here is one of the kimbers, they are selling adapters to 5/8 too

Nice! Got lucky bud, all the others that have been here have been .470ish.
