This Nitrolon body extender converts your G2 flashlight into Ni-Cad rechargeable flashlight using the B65 rechargeable battery. NOTE: The conversion makes your flashlight 2.1" longer. If you convert, don't forget to order a CN211 charging unit (see right) and extra B65 batteries if desired. Or you can order the complete KR1 conversion kit, which includes one Nitrolon body extender in your choice of color. To convert the aluminum-bodied 6P, Z2, or C2 flashlight order the KR2-BK conversion kit.
