I was exposed to the metric system in the time I was in the Marines and was amazed at how simple the system was and also amazed at why the US did not change to that system, it all boils down to money.
I been shooting an A2 with irons in 2-gun matches since before the A2 clones were becoming a thing. It’s a little slow with the close in stuff, but it shines on the longer range stages. And to be honest, my A2 is my most fun gun to shoot. I’m way faster with my lighter, shorter and optic mounted guns, but shooting matches with the A2 is akin to the on deck batter warming up with a heavier/weighted bat before he steps up to the plate.
I'll be the first to state the real truth in this. There are two types of countries in this world. Those that put a man on the moon and those that use the metric system.😃
