Pretty much any well built AR will stand up to that abuse.....and keep in mind Larry Vickers is paid to endorse DD's product. That being said DD makes a very high quality AR and Larry Vickers is regarded as one of the best, if not the premier, combat firearms instructors in the US and certainly puts more rounds down range then all of the members of this board combined on a yearly basis. If Vickers is willing to put his name behind a product you can be assured that it is a quality product.
