I got 2.5" circumfrence on the barrel, and 2" on the m203 mount. Give or take an 8th of an inch.

Lol, he wants diameter not circumference.
It's about 3/4 of an inch by the way.

2.5 / 3.14 = 0.796178344

He could have figured that out himself. Wanted to post the measurements that I took. Nice round numbers.

So that is 20.22mm...those are fucked up sizes...are they all that size?
Then I will have to custom machine some bushings up!

I didn't have a proper tape. Those are the best dimensions I can give. Probably not something to base machine work off of though.
