Rifles That Have Two-Piece Scope Mounts Interchangeable With Bergara BA13
As detailed in the main article on interchangeability, the Bergara BA13 can share two-piece scope mounts with quite a few rifles. This means that while these rifles may not all have the same B distance as the Bergara BA13, they do share all other critical mounting parameters such as A and C distances, radiuses, and BHU.


Below is a list of all rifles that have two-piece scope mounts interchangeable with the Bergara BA13 mounting surface.
Mounting Standards With Interchangeable One-Piece Scope Mounts
Given the list of rifles that have two-piece scope mounts interchangeable with the Bergara BA13, there are certain cases where a specific group of rifles within the two-piece interchangeability list shares a certain B distance, creating its own sub-standard.
This means that rifles in such a group will have two-piece scope mounts interchangeable with the main mounting surface of the Bergara BA13, but will also have one-piece scope mounts interchangeable between themselves because they share that same B distance. This article will explain the sub-standards and provide a list of rifles for each standard.

To make things clearer: all the rifles listed below should have two-piece scope mounts interchangeable with Bergara BA13 and one-piece mounts between themselves.
Bergara BA 13
The Bergara BA13 is a single-shot model within Bergara’s BA series. The rifles listed below will have two-piece scope mounts interchangeable with the Bergara BA13 mounting surface, but will also have one-piece scope mounts interchangeable among themselves because they share the same B distance.
CVA Accura (old)
The CVA Accura, an older model in CVA’s muzzleloader series, features a break-action design with a hinge assembly connecting the barrel and receiver. The rifles listed below will have two-piece scope mounts interchangeable with the Bergara BA13 mounting surface. These rifles will also have one-piece scope mounts interchangeable among themselves because they share the same B distance that is the same as on Accura.
