A kit for modifying a firearm such as a Kalashnikov assault rifle, better known as the AK-47, so as to permit the bolt carrier to be pulled back easily with either the right hand or left hand of a user. The kit includes a receiver cover including an arch-shaped crown and a pair of retaining fins that are affixed to the bottom of the crown. Each of the retaining fins has an upper portion extending outwardly and downwardly from a respective one of the opposed sides of the crown. Each of the retaining fins also has a lower portion that extends downwardly from the bottom of one the upper portions. One of the retaining fins is provided with a slot that extends along the length of its upper portion. A guide track is affixed to the retaining fin having the slot. The guide track has a pair of retaining flanges disposed on opposite sides of the slot. A charging handle assembly is secured to the guide track and includes a slide that is slidably engaged with the retaining flanges and is adapted to move along the length of the guide track. An auxiliary charging handle is affixed to, and projects outwardly from, the slide. An engagement pin is affixed to, and projects inwardly from, the slide. The engagement pin extends through the slot so as to engage the bolt carrier of the firearm and move the bolt carrier when the charging handle is pulled rearwardly.
