I have recently purchased the 715t with carry handle and 18" barrel. I want to take off the carry handle and add a combo optic 3-16x or similar with the red dot also on it. also want to add muzzlebrake and remove front sight. Does anyone know, since i haven't picked up the firearm yet, if that front sight is on by itself or if it is part of the forend? The name of some places to go shopping would be helpful. by the way, all of you who post on here have great thing to say. this is my first gun and am very excited to start using it also what does anyone reccommend for ammunition? 36gr or 40 for this firearm?
