My 300 blackout pistol build for my Suppressor

[jertex]

I received my YHM suppressor a few weeks ago and quickly realized that using it on a rifle w/ 16" barrel created an extremely unbalanced, heavy gun and I started searching for the right pistol brace to create a new pistol build so I could use a shorter barrel to improve balance & reduce weight. I decided on the SB Tactical SBPDW, picked up a 10.5" barrelled upper, bought a new lower and I now have a very nice pistol build with much better balance & almost a full pound lighter. Now I definitely want to get a 8.5" .556 upper for the build as well.

I am really pleased with my AR pistol project.

I built a .300BLK SBR and chose an 8.5" barrel. I dig it.

I had mixed emotions on the 8.5" Barrel & 10.5". I eventually went with the 10.5" because of the 9" of barrel needed in most instances to fully burn the powder & trying to strike a balance between a shorter barrel and velocity. Of course, the 8.5" would have been even more balanced and easier to handle so everything is a trade off. I guess I'll just have to force myself to eventually get an 8.5" upper as well.

Depends too if you're using factory ammo or loading your own. Shooting subsonic you don't necessarily want to get that additional burst of velocity out of it. I live in an area that gets quite cold in the winter so we load our subsonic ammo slower than you would in say Texas.

I went with 10.5" for the very same reason. After running potential loads through quickload I was pretty well settled. Balance of the (at the time) pistol didn't matter too much because I knew I was going to be turning it into an SBR at some point.
