Micro Barrel Dimensions

[DOD 7.62]

Does anyone have a diagram showing the dimensions for the ports on a Micro barrel?

Not a direct answer to your question, but looking at mine, I see no difference between the Micro and the Mini comp cuts.
The angle of the slots is important.

This is a comparison pic I did a long time ago of an IMI barrel (top) and a Green Mountain mini barrel (bottom) with my measurements to show how Green Mountains comp slots were ever so slightly smaller. Like Jack007 said, I think the slots are the same from mini to micro. Hopefully someone can come by with some more precise measurements and the proper angle...

Thanks that’s an excellent start, very much appreciated. I see the set back measurement from the muzzle to start of first port as 5mm at the top, do we have a set back measurement at the bottom of the first port to the muzzle? That should give me the angle.

10mm on the mini barrel.

Are you slotting more than one while setup?
What length barrel are you using?

10mm on the mini barrel.

Thanks, for that, should be able to make it work. I’d assume it a safe bet mini and micro would have the same vent dimensions.

No, not likely. Just the one. Raw blank, but I understand the correct Micro length is 134mm.
