The 300 yard intermediate cartridge/rifle concept wass revolutionary all things considered. And now with new loads and or chamberings you can cross over from the intermediate concept to an almost full blown battle rifle; but in a feather weight little toy "plastic" carbine. An honest 500 yard killer. It is a concept hard to ignore, since all small arms are a compromise between this and that, I hate to admit it cuz I used to hate AR's but all things considered a proper AR seems to hit the sweet spot. Kinda like anything chambered in 6.5! LOL
