And an Allen key...or a 350.00 adjustable brace. You won't have a rubber butt stock, and you won't have cheek rests if you're like me and spent a long time on a SOPMOD style stock. Don't get me wrong I love and own AR pistols too, but when you own an SBR you'll realize the 200 IS worth itYou can do all of those things with a pistol brace as well.
