Ive considered getting the .22LR but was told once Ive shot it a few times Ill want something with "more balls", hence looking into the m&p15.. If i can find one I think Im going to jump on it but with the demand as it is its going to be tough. Im trying to get one custom made considering my buddys friend will do it for next to nothing considering what it will be. Im in NY and the gun laws are ridiculous, I originally wanted an XD-M or m&p9mc but because Im not a NY resident but a Fla resident I cant even touch a pistol and be legal, HOWEVER I can own a semi-auto rifle and shotgun comepletely legally without a permit, pretty dumb if you ask me. So this is why I want something that enjoyable to shoot..
Edit: I really dont want to spend over $800, thats why this is appealing to me. Obviously with everything what you get is what you pay
