This is a light weight, accurate and dependable patrol rifle. No malfunctions during range sessions as of this posting. It is balanced and handles very well. No problems sighting in. This model has flat top upper receiver, folding rear sight and standard front post. The only accessories that you should consider adding are good white light source, tritium night sights, your favorite CQB red dot sighting system and a good sling system. Oh and lots and lots of ammo because this rifle is fun shoot.
