New guy here. Figured I would show you guys something a bit fun for my first thread. This is much less of a how to and more of a friendly discussion on the gun as well as introducing myself a bit.
The MP5SD was this unicorn of a gun growing up to me. One that I had only seen in pictures and was very unique. The unique thing it does in case you are not familiar is it takes standard 9mm ball ammunition down to subsonic velocities to prevent a supersonic crack that you can experience with lighter 115 and 124 grain loadings. It accomplishes this by several ports just forward of the chamber which then bleed out into a large expansion chamber in the suppressor. Coupled with a large 12" reflexing suppressor it is quite the quiet gun.
Here is a box full of parts needed to make a MP5SD. I used a LSC flat, RCM BCG and trunion, a Swiss B&T barrel, and a TPM suppressor
Flat is bent and barrel is headspaced in the trunion
Checking fit
Then the magic gets put into them
Then I refinished it in the nicest epoxy paint Lowes had to offer. I then worked up a solution using modified Mlock rails to mount some goodies to it. The one bad thing about the SD is the lack options to be able to mount accessories.

Video of it getting built up and another of it getting some use
