CZ USA is now making suppressors as well as integrated versions. You can also see the new smaller Scorpion called Scorpion EVO III S2 Micro
Dasan Glock lower
This Glock lower was worked by Paul Kim who is more known for his works with SureFire lights. It uses simlar design as a STI 2011, where grips can be replaced easily. Dasan has been making Glock barrels and slides(through Lone Wolf Distributors) so they seem to be the chosen manufacturer.
Palmetto State Armory 9mm AK and MP5 clone
PSA came out with AK a few years ago and this year introduced AK in 9mm. It currently takes H&K MP5 magazines, but Glock magazine version is in the works. PSA also showed off their MP5 clone, although it is some time away before it hits the shelves.
SureFire came up with 1000 lumen weapon light that has green lasers as well.
SMGLee posted new red dot sight from the Wilcox Industries that has ballistics, laser designation as well. (and internal sights in case?)
Chris Bartocci covered the first day with Brownell's Retro guns, SIG pistols (2:12), Troy(8:23), Caracal (10:18), YHM(11:07) and Geissele's URG(12:37) that is actually going to be equivalent to SOPMOD Block 3.
