BSA Scope Instructions

BSA Optics was formed in 1996 out of the British company Birmingham Small Arms -- or BSA. BSA produces a wide variety of scopes for rifles, handguns, shotguns and even longbows. BSA is known for producing quality optics at affordable prices. BSA produces scopes for various shooting needs such as target shooting, hunting and tactical shooting. Regardless of your type of scope, the basic operation of the scopes are consistent among the different models.

Instructions

- 1
  Zero in your BSA scope with the adjustment dials centrally located on the top and right hand side of your scope. Zeroing in your scope consists of aligning your scope's cross-hairs with the projected point-of-impact of the rifle bullet by moving the cross-hairs accordingly. You can determine the projected point-of-impact by either using a bore sighting device or by firing a live round and using the bullet hole as a reference. To move your cross-hairs along the vertical plane, turn the top dial clockwise for down or counter-clockwise for up. Move your cross-hairs along the horizontal plane by turning the right-side dial clockwise for left and counter-clockwise for right.
- 2
  Adjust the magnification setting -- if your scope has variable power -- by turning the variable power ring located on the scope's eyepiece to your desired magnification.
- 3
  Adjust your scope for parallax error -- this feature is usually found on long-range scopes -- by adjusting the dial located on the left side of the scope adjacent to the cross-hair adjustment dials. Set the dial to the known distance of your target. Parallax is an optical illusion of target movement sometimes encountered when your scope is set for long range and high magnification.
