What are opinions for optics on a AR 300Blk? Subsonic ammo. Would like calibrated reticle for sub ammo.
Thanks

You're not going to be shooting long range with it so low power is the way to go IMO. EoTech makes a sight with multiple dots set up to Black Out trajectory that might be worth a look. Nikon also makes a 2-7 and a 1-6 that have dots for the BO also.

+1 to nothing to fancy. You're looking at lots of drop over 150 yards and decreasing energy. I went with a 2.5-10x and it's plenty. So much fun with subs and a suppressor, just know the limitations.

Leupold makes this one if you want a scope with a turret calibrated for the 300 BLK: Leupold Mark AR Mod 1 300 BLK

Nice thing is the mil/mil setup.

I am running a Vortex with the XLR reticle. Works great once you run the ballistics.

I run a zero mag red dot on mine. I mostly just shoot rabbits with 110 vmaxs at supersonic speeds. I did have a 3-9 on it when I was working up loads. I worked up a good subsonic load with 208's, and good supersonic loads with 110's for varmints and 125 nbt's for deer and then switched to the dot after the loads were figured out.

For what you're wanting you might try the midway weaver 3-10 mil/mil and dial your own elevations or run them off the mil reticle on the fly.
