Improvements Needed
Kit is fine but for a few problems. The first is that the roll pins that are included are not "roll" pins but "rolled" pins. This type of pin is an inferior product that tends to easily have its center punched through, thus ruining the pin. The second issue I had, was that the included "rear takedown pin" was an unfinished product that did not have the final machining or refinishing performed on it. This is probably a fluke, but it forced me to go out and procure a replacement that should have been unecessary. This is a decent Low Cost kit, but DoubleStar can do better than this.
