Since there's not much talk of SHOT 2012 here, I figured I'd at least link to the subforum on m4c covering SHOT.
Here are links for SHOT Facebook page images
A quick recap of the things that stood out to me...
• 2 MOA Aimpoint T1
• Surefire's new 500 lumen X300 ultra, 500/15 lumen LX2 as well as a couple other 500 lumen lights and a new IR X400.
• Surefire mini 7.62 can
• AAC new 90 tooth adapters, discontinuing of the MITR mount and the new mini 7.62 which will be smaller than Surefire's mini 7.62.
• LMT's new lightweight LR8 MRP and MWS chassis as well as some other products related to the monolithic chassis
• Knight's Armament's new URX 3.1 and new versions of the SR15 and SR25
• Tavor available to US customers
• New factory barrel, including the 10" 5.56 and 13.5" 7.62, for the SCAR
• New factory barrels for the ACR
Plus other stuff popping up here and there as well as some nonsense like EoTech's Zombie (BioHazard) reticle.
