I will soon run CFD on it but the analysis usually takes a few days to run -_-

have you shot it yet?

general rule is the more can in front of the muzzle the better but you have a lot of volume "back there".

Yeah you can tell by all the debris on the baffles in the 2nd to last picture. I wanted to make something that would bring the center of inertia closer in. This model is 10" long but only 3" extension off the end of the barrel.

yeah i see what you were getting at in keeping it from being front heavy.

so how good does it work?

Very good looking work and a unique concept of diverting the gasses backwards. I think that it would be better served if there were fewer baffles on the back because with this concept the goal would be to get gas flowing backwards as much as possible.

How does it sound though?

It sounds great! I have yet to get some quality figures on it though I can't seem to find any decently priced microphones that will measure decibel readings

I agree.......and why is the forward one which is closest to the hot gases the thinnest
and the others were made so thick.

Ha... Decently priced. You are looking at a few thousand dollars to get the set up that can actually read impulse noise. They aren't exactly a popular high production item.
