Just finished my micro 223 suppressor. Its 3.7" long x 2" diameter. I built it to fit the same muzzle brakes that I made for my compact 223 suppressor.
This is close in length to the KNX muzzle brakes
The body, mount/blast walls, and end cap are 4130. The baffles are 17-4 stainless.
I had to use a shallower cone to fit three baffles in the short space. This was the first time I tried leaving the spacer on the cone side like an M baffle instead of the traditional built in spacer on the cone baffle.

Micro on top, my 5" compact build and then a commercial 223 suppressor


On the 7.5"

Those are nice, Good job!!

How does it sound?

Just finished it today, once things thaw out I'll go shoot it.

Man I want to learn how to do this, so I can build some for myself!

Always impressive!

Awesome as always man. How does it sound compared to the compact?

Nice!

Looks great!

You should name it the "lil chub"

I finally got to try this one out today (we had our first child 4 weeks ago so time is scarce). I shot it on my 7.5" upper which is the loudest thing I have. It was slightly louder on it than my longer suppressor but was actually comfortable to shoot without hearing protection.

Very cool and impressive.
