I just got a 10.5 pistol from psa in 300 blackout. It has mbus sights on it. I'd like some opinions on using a red dot vs a 1-4 or a 1-6 scope. This is my first ar pistol. Pretty excited to run a few rounds through it. For now the back up sights will suffice but I want an optic, just unsure on what will serve me best. This will be a bit of a do all for me.
