Oh boy, what have I bought? This is a tough question, because I've bought/sold/traded so many over the last 10 months.
I distinctly remember getting the following since January '05:
S/A M1A Scout (sold it)
Colt MT6400c post-ban M4gery
LFT-15 (custom made AR-15 lower)
Rem 870 AOW
Para-Ord Colonel
Taurus 85 (sold it)
Sig 226 9mm (sold it)
P22 (sold it)
NEF Youth .22lr
I've also been spending quite a bit of money on accessories, such as:
Surefire 618FA foreend for my 870P
Surefire M900A for my AR
DPMS 11.5" upper for my AR
EOTech 551 A65
.22 lr suppressor from ETS, Inc.
.223 suppressor from ETS, Inc. (serial number and model to match my custom lower)
several NFA tax stamps
I think I bought several others back towards the beginning ot the year, but I got rid of a lot of guns this year. Like Preacherman, I've been thinning out the herd, getting rid of things I don't shoot and keeping ones I'll actually get the chance to shoot.
