Conversion Kit is a specifically designed adapter that converts the ignition source of Accura MR-X and LR-X rifles. The Kit comes with two parts, the breech plug itself and the Variflame priming and punch tool set. The breech plug (also known as the Quick Release Breech Plug or QRBP) can easily be fitted with a QRBP fitting tool that comes with the QRBP as well as simple step by step instructions. Once the QRBP is properly installed no tools are required for installing or removing QRBP. The second portion of the kit, the CVA Variflame Priming and Punch Tool set, assists the user with setting a large rifle primer into the Variflame Adapter and more easily removing the primer once it is used. The factory made priming tool was specifically designed to help avoid accidental detonation of a primer.
