Yeah availability of parts and accessories is definitely a big advantage in any gun, and the AR15 (along with the 1911 so many of us are in love with.... And yes, I'm crazy about the 1911.) Defintely is well covered in that area. I'm sort of releived to hear there's at least 2 others out there who don't hardly bat an eye at AR's. And NO, I'm NOT like Mr. Zumbo. I don't consider them Unnecesary or terrorist rifles, and I wouldn't be against hunting with it. Being a hunter I see hunting potential in all of the long guns I buy, and some of the handguns, as a matter of fact. Like I said, AR's are accurate at ridiculous distances, easy to use, light, and all over the place, but they don't excite me for some reason. I AM nuts about cowboy and WW1 and WW2 guns (Probably all the John Wayne movies I've watched.). Or a big bore DA revolver like my redhawk .44, That will get me to droolin'. Or a nice Side by side shotgun.
