Product Info for Talley Picatinny Base for Kimber 84L

These picatinny rails are machined from solid bar-stock 7075 T6 alloy and then bead blasted for a rugged, lightweight and long lasting finish. The slots on the rails are designed to accommodate the Talley Rail Railmount adaptors for firearms with a Cheetah 84 trigger guard.

Please note, some fitting may be required. These rails do not clamp firmly to the frame, so please be careful to take proper care of your firearm. Whether you are a do-it-yourselfer or looking for help with a build, we want to make your shooting experience enjoyable.image
