Good Morning, psycodaog,
Browning has always been synonymous with quality. Some hunters have opined that Miroku rifles are equal (some say better) than FN models. I can't offer an opinion because I don't know. Japan does make very good steel.
The .308 Win is almost mythical. It works far better than it should. Many years ago, it surpassed the '06 is sales, probably due to semis chambered for it. The reality is it'll duplicate '06 loads which translates to filled big game tags. It's extremely accurate.
If I were to run across a .308 Win carbine, I could sell my big game rifles. I wouldn't, but I could.
A single shot with a 20" barrel would work, too. Heavy rifles at altitude = bad attitude. Light rifles = happy hunters.
Bottom line: congratulation, you are the proud owner of an excellent rifle.
