Picatinny/weaver rails

They will be different because the receiver mounting holes are not standard from gun to gun.

If your V3 is already drilled and tapped, get the rail for that model. The holes on the firearm should line up with the rail. If your V3 isn't D&T, you can get whatever rail you want and put the holes in the receiver where the rail sits. I am putting a rail for a 10/22 on a Mav 88 the same way.

Just had a hard time wrapping my head around how the tapped holes are not the same for all rifles and shot guns, or at least limited to a few different configurations. I'm stubborn like that

I had the same thought. Grab a couple of your rifles that are D&T for mounts and measure. Action lengths are much different. A 10/22 has holes drilled much closer together than a shotgun. Manufacturers also want to drill in areas where the metal is stronger and not have scopes mounted to relatively thin metal walls. So they will move holes around to where there is thicker metal. I am also stubborn. Which is why I am D&T my shotgun for a rim fire rail instead of buying a new one or another shotgun.

Do you also think it strange that all V8 engines don’t share common exhaust manifolds?

That always bothered me!
