Hello,
I have wanted a large frame AR for a while and was set on getting a GAP-10 until I read about the JP LRP-07 on here. I think I have decided to put an order in for one soon. My debate currently is between getting the .308 version or the 6.5CM. I know the CM is a flatter, longer shooting cartridge; however, it's also more expensive to shoot and the barrel life is less. Because of this I am leaning towards the .308 for now, with the thought I can get a 6.5CM upper or another rifle in the future. I also sort of feel I should master .308 before moving on, and should have a .308 semi. I do reload when I have time (which with my current work/life schedule isn't often), but mostly I buy plinking rounds from the local sporting goods shops. I am still relatively inexperienced with distance shooting, but want to get some experience and likely some training. It will mostly be for range shooting, and maybe occasional hunting.
My question is, am I missing out on a huge benefit by going .308? The build I am thinking of is below if anyone would offer suggestions/tweaks for it:
