S&W has gotten some great sales out of their S&W M&P-15 rifles, and this year it looks like they’re expanding into the AR-10 area as well. Their new M&P 10 features an 18″ barrel that is not free floating, and apparently comes with no sights (yet has a railed front sight base for flip-ups if so desired). No word on MSRP, as I couldn’t get one of their reps to stand still long enough. Comes in .308 Winchester, and appears to take standard PMAGs. Which is great, since they just upped the round count on those to 25. More info in this here post.
