For those a bit removed from the loop, SHOT Show has been going on in Vegas for the past 2 days.
Magpul has had the most exciting stuff, including this wicked awesome Unimog. Aside from that, much of the other new goodies can be seen in their gorgeous 2010 catalog, available from their newly updated website . Magpul has some seriously skilled photographers and graphic designers, that's for sure. New stuff includes - rifle and midlength MOE handguards, polymer rail sections for the MOE handguards, MOE rail and picatinny rail versions of a stubby VFG, and new PMAGs--including a 40 round PMAG.
