Thinking of picking up an AR -15. I dont think I really need another gun, but I have been wanting one. I rented one Sat and had fun shooting it just dont think I "need" it. Until now, most of my guns have been very cheap and fall into the category of their cheap and I can pay easily with saving a few weeks pocket money. No different to me than going to Harbor freight and picking up some tools. Then I decided I wanted a nicer gun. Found an ok deal on a S&W M&P. I like it. I doubt I will ever get rid of this one. Was thinking of spending on an AR with the same attitude - having it forever. Not talking a $2K AR, more like a S&M M&P 15 ($600) but something I will have for the rest of my life. For long guns, I already have a Ruger 10/22, 4595TS and a mosin (but I think the mosin is more just something I wanted to collect - I have had some feeding issues and have trouble finding a place that lets me shoot the surplus ammo I bought) So why should I or why shouldn't I?
