I've done a lot of trading and a little buying. Current "new-to-me" stuff.
AR-15 in 223 Wylde - Bushmaster (pre-Remington buyout) upper and lower, Rock River 20" bull barrel, Chip McCormick Super Match Trigger, LaRue tactical 12" quadrail, detachable carry handle, bipod. Bought it about a month ago.
1911 - Remington Rand "P" slide over an auto-Ordinance frame. Trigger job, slide job and more extras.
Ruger Mini-30 (with 6 magazines)
2 Ruger 10/22's - one fully loaded with bull-barrel, etc. Bought from same guy as the AR
Hi-Point carbine in 40 S&W. Fairly cheap guns, but fun as heck to shoot.
Hi-Point pistol, 40 S&W with laser
Ruger SR40c (for my wife)
Winchester Model 70 Ultimate Shadown in 7mm WSM - Got this one primarily for the scope (Zeiss Conquest), but like it surprisingly well overall. Just picked it up today. Fate TBD, other than I'm keeping the scope!
Like I said, I've spent some money, but traded a lot. There are deals to be had right now, you just have to look really hard. Picking up a Leupold Vari-X III 6.5-20x 50mm tomorrow for the first gun listed. Pretty sure I did really, really well on it. They sell for $900 new.
