I did notice one private sale table that I though the asking prices were nearly retail. Maybe the guy likes to haggle.
I think the high point fo the was the SRM shotgun booth. A tad pricy at around $2,300 but interesting with the external rotary 4-tube magazine. In the full size version that give you 16 rounds of 12 ga. in a not-too bulky looking package (i.e. not extended magazine hanging down or drum).
It was kinda like an xrail, but not something you can retro onto a different shotgun. Also, you had to manually rotate the tubes, unlike the xrail. It was almost kinda cool, but VERY expensive and really only a tacticool sorta thing. The only upside I see to it, is that they are made in Meridian, so it is good for the local economy. I don't see it being of any use in competition, that I am sure of. No chokes, short barrel and really slow to load.
I'm trying to think what it WOULD be good for besides showing it to your friends and showing it to people at a gun show..?
