All shrewd scopes are machined with a recessed hex pocket to adapt to a standard round, hex, or square scope mounting rod. This feature is designed so the scope will not rotate on the mounting bracket.
When mounting the scope onto a scope rod the included hex nut on the outside of the scope should be removed before the scope rod is threaded onto the 10-32 threaded rod.
In some cases the longer 10-32 rod should be substituted for the shorter, 1-1/4" 10-32 bolt included in the packaging.
Square pocket measures .314" x .314"

Compatibility:
B3 - Requires the use of the 10-32 x 1/2" button head screw that comes stock with the b3 sight when mounting the scope.
Axcel - Can mount to the stock axcel scope rod but will require a 10-32 x 2.5" button head bolt or the     stock scope rod can be replaced with a 1/2" shrewd scope rod.
Spot Hogg - Requires a 3/8" shrewd scope rod.
Sure-Loc - Can mount to the stock scope rod but may require a 10-32 x 2.5" button head bolt or the stock scope rod can be replaced with a 3/8" or .455" scope rod depending on the sight model (see scope rod product description).
