I got a question for you fellas. I just purchased a benelli M-4. Nothing in my collection is stock it is all tactical and I'm looking to beef up my new M-4. I've been looking for the past several weeks online trying to see what is out there but I really don't know what to get. I only want the best. I was thinking about getting the collapsable butt-stock, mag extention, sling, ETC. Something like MR. Hooksters', if you haven't seen it check out his pics best I have seen. If you guys can help me out and let me know what to buy and where to go that would be great. Thanks for everyones time and consideration. Luckymac
