What are you going to mount the sightmark on?
300BLK is nice.Trying to decide. Was leaning towards a 300 Blk AR. But now I'm not sure. I thought maybe a 224 Valkyrie AR, but I think I want to keep that long range for antelope. Likely the 300 as I plan to hunt mostly pigs with it, and my shots are no more than 130 yds.
