I really want an ar15 for my birthday i have enough money to buy a colt if i wanted but ive seen other really nice ar15 rifles for 850$ or less like the palmettos state armory ar15s or the s&w mp 15 i want a rifle that i can take to the range or dessert and run it hard or go varmit hunting with or if shtf i want a rifle that will be reliable and i can really depend on it to protect my family, and my life ,a rifle that will last. people are saying to get a colt beacuse its particle tested used by military mil- spec quality f marked front sight m4 feed ramps blah blah blah, but is is it really worth buying a colt? Or will a rifle that cost less do the same thing? Why do so many people love colts? This will be my first ar so please tell me what you think.
