AR Pistol build questions

Hey all,

         Just a quick question.  I am planning out an AR Pistol Build, and really know very little about what is going to work best.

10.5" AR Pistol 300 Blackout

Do I want Pistol length or Carbine length gas system?

Also would like suggestions for best budget lower. I have already looked at PSA, Anderson, and Aero Pre… Any and all help is greatly appreciated :nerd_face:

pistol length if you will shoot sub-sonic ammo which is whole purpose of 300 BLK…

Pistol all the way. Also, highly recommend Aero Precision lowers.

I found my lower from PSA, going to make this much easier for a first time budget build👍🏼

I built an AP recently. I’m very impressed with the quality and would buy another.

Pistol if you want to shoot lots of subsonic. If you are going supersonic exclusively then carbine. Don’t have your length here but it gets you in the park.

Thanks, that’s interesting. Something I never thought of. Looks like I am going to learn some stuff with this build.
