3 lug Uzi Question

[Remo Williams 1]

I just got some barrels for my mini Uzi that I would like to have 3 lugged. What is the distance from the barrel tang to the 3 lugs, so that the suppressor had room to engage the lugs? Thanks.

Picture of the IMI Polygonal bore barrels I was selling a long time ago.
The barrel was threaded 'Gemtech spec' by Tros where the adapter was threaded almost the entire length.
I measured one and the back of the lug to the front of the flange is 1/2" on mine.

Awesome. Exactly what I needed. Thanks
