I have 5...4 in 223 and one in 7.62X39 (the wifes hog
it has a 20 barrel flat top w/ lit 3X9X40. One has 20" 223 w/ 3X9X40, one is the "Lady Carbon 15" for guess who w/ 6x scope, one 16" 223 flat top with a carry handle and one 16" 223 flat top w/red dot with all green furniture.
The wife bought me one, Bushmaster 20" 223, and I was one of the "who the hell needs one of those dam things" guys until I shot it a few times. So I bought her the Lady Carbon 15. They were so expensive, but we wanted more...so I started building them myself and the last 3 base cost was just a little more than my 20" Bushmaster.
I just built one for a friend last week 10-6-08 and I only had $550 dollars in it when finished. The price has not started going up yet!
I also built some AK's and use one of them for hunting, it's my hog gun. I tricked it out with black plastic and a quad rail front fore ned and added a rail to the top dust cover. Having built it myself I made the fit tight for the dust cover so scope setting are not floating around. The 7.62X39 is just as good as any 30-30 at stopping hogs and deer at less than 75 yards.
