Re: Why FN SCAR?
ARs are the ultimate lego rifle and can have the best barrels (and other components) on the planet put in them: by the owner. Name one new-fangled rifle that allows you to put in your choice of barrel, trigger, handguard, buttstock, sights, etc?
AR's have been used in combat longer than any other US rifle: the DI system must not be that bad. Furthermore, the lack of a piston gives an AR the incredibly ergonomic feel we all know and love.
With a top-notch barrel, properly chambered/assembled, an AR sets the standard for accuracy among semi-auto rifles. What non-bolt rifle in 5.56 (or 308 out to 600) has proven to be more accurate than an AR? None. What are the winners at 3-gun matches using? ARs. What wins service rifle competitions at 200, 300, 600 when you pit the M-14, M-16s, and M1 against each other: M-16.
Let's face it. The M16/AR15 is the standard to beat in so many aspects. There are some cool new rifles out there, but it's a stretch to claim they are better in any measurable ways. If they are better, then I'd expect them to start dominating some competitions: haven't seen that yet.
