Ideal supressor thread?...

[Jaco Goosen]

Ideal and most common is 2 very different sizes.

Ideal: As big in diameter as possible, no less then 1mm smaller than the barrel diameter at the crown.

Most common:
Ultra light barrels: 1/2" x 20 or 28tpi
Hunter profile barrels: M14x1
Varmint barrels: 5/8" x 24tpi or M18x1.

Hope this helps.

I normally work on ideal size.
