Also, some of the HK G3 replicas and FAL replicas aren't too bad either.

They're pretty reliable and almost as accurate as an AR-10 style rifle. Some get 1-2moa with good ammo (sometimes less but it is rare) and 2-3 moa with bulk ammo.

If you can catch the match grade .308 on sale you can get it for ~$1.25 a round while the bulk brass stuff is between $0.75 and $1.00 per round which makes it a no brainer to go ahead and get match grade .308.

If 6.5cm ever comes down to .308 prices then I think I'd rather have that, ignoring parts commonality and ammo popularity in a SHTF situation that is.
