if i'm off on anything, i'd welcome any corrections.
i went msany moons ago with a 16" pre-ban carbine because my purpose is plinking at moderate(100-200yds)ranges. i suppose you can hunt at that range, too.
1. i'm a short guy, so a 16" handles best for me.
2. flat top version because of the flexibility in optics. you can purchase a carry handle for around $70 in the EE. i'd hold off on scopes and red dots for now until you're versed with the rifle.
3. pre-ban because you're in a free state and can install a telescoping stock. i love these stocks because you can adjust length-of-pull, what you do give up with traditional iron sight is a solid cheek weld that a traditional stock gives you, but the cool factor can't be beat...lol
4. bushmaster gives me the right combination of price, quality, standardization of parts.
5. regarding magazines, buy usgi and unless you like new shiny mags, i'd buy used ones for around $15-$18, maybe even $12. the things i look for are uncracked feed lips and intact baseplate tabs, straight baseplates and good welds(although welds always seem to be solid). i wouldn't care about finish because you're lucky to live in a free state and can choose from millions that are out there. the EE always has good deals. U.S. made thermold mags are good, too, and they look great on the rifle.
6. for now fight the desire for lights, forward grips, magpuls, bipods, grips, slings and all the accessories out there. they're great, but they are accessories and are better suited when you're better versed with the rifle.
7. ammo is the important thing. you really can't go wrong with name makers. they're all pretty accurate, and there are some nice deals floating around from industry forum partners. you'll read about wolf until the cows come home. bottom line for me is they're fine whether with my bushmaster or ASA(yes, ASA!). ammo is really touchy with people, you'll just have to shoot various kinds and find what's best for you.
my current, favored setup is a bushmaster 16" pre-ban flat-top with an eotech 511(the old blister button kind) and an ARMS 40 backup iron sight. i made a ghetto tac-sling out of a standard silent sling and some paracord. simple, light and works great for me.
8. check the EE for your first rifle, there are some nice deals that come up all the time. pric-wise the pre-bans seem to run around $1,200, but you can buy a pre-ban lower and use a post-ban upper and save a couple hundred.
i hope all this didn't further confuse the matter. and i would welcome any corrections.
regards,
tony
