I did have another side question, more about practicality than anything. So I've read - and my manual states - this rifle was sighted at Arsenal with their laser bore process. I've put 600 rounds through it. Shooting a 30 round mag at a 10"x10" target, I can put all 30 on paper at 100M. I'd say the majority of them are within a 5"-6" group. The reason I've focused on 100M is that I doubt I'd have any life or death encounter beyond that living a major urban area.
Now, I didn't buy this rifle for competition shooting - nor do I expect this platform to provide 1" groups at 100M, 200M or 300M. I bought it because 1) I loved it and 2) for a SHTF/defend my life scenario. Am I wrong in thinking hitting a 10"x10" target is sufficient at 100-200M? I'm not an expert rifleman by any means, so I know through practice I can probably get that group tighter.
But in a SHTF scenario, I won't be sitting on a nice chair, with my gun wresting, breathing nice and smooth without a care in the world. My goal is to hit a chest-size target.
