I would think that the 1-4 would be all you would need though.
With the 1-4, maybe I don't need the dot. But I think the dot is always faster than a scope, and both eyes open.
But I would not be against a little more mag for 200 yds.
I've been thinking of going through him. But I wanted some research and other people's views first.
Was gonna go with the Vortex Viper PST 4-16x50 FFP on my M1A and possibly add an offset Burris FastFire, lol.
I might wait though. I kinda want to get a loaded or a SOCOM and add that EBR stock setup and do it on there.
I also started looking at the 4-16.
