I have read all the old post on these guns but I want any new feed back. I'm looking for a home defense AR that won't break the bank in case of theft. Through my research & discounts these two gun are $570 vs $590 with free shipping. The slight price advantage to S&W. Any input is welcome as I am an experienced shooter but an AR rookie. I especial welcome hands on experience with these weapons like malfunctions & reliabilty. Thank you in advanced for your input.
