Re: Buying a 308 WIN...help
My opinion would be to find a quality bolt gun leaving you at least 400 bucks for a different weapon for home defense. You can find a extremely nice bolt gun for under 1600 especially if your patient and look on gunbroker. I found a friend a custom hs presicion with only 200 through the tube for 1300 and it shoots like a gem(1/2 moa). The rifle costs alot more brand new so he got a hell of a deal.
Then go buy yourself a 16-18in barrelled shotgun that holds as many shells as possible probably about 6-8. Fill the shotgun with bird shot. The shotty will be a perfect home defense gun, with the bird shot you don't have to worry about going through walls and hitting someone else, ie family members or the next door neighbors. You will not have to worry about missing an intruder either.
Just my 2 cents but also realize what a man wants is what a man wants and if your set on a semi auto then go with the semi auto. I do have a DPMS in 223 with a 24" heavy barrel that shoots great, however I also have a friend who has a 223 dpms with a 20" heavy barrel that were having trouble with it shooting even 1moa, but were still trying to find a load it likes. I can't comment towards the armalite because i have never shot one, but I do enjoy my dpms.
