not true, the fix is simple If you cant find the part, change the locking system, take the cover off, and drill a hole in the top center of the cover so you can use a nipple wrench, a # 209 nipple wrench used for muzzle loading guns fits perfect, you can find them @ gun shops, farm & dept stores that have a gun sporting section. A $7- 15 fix. you use the wrench as an armature lock
