Leupold 1 Piece Base Standard A-Bolt

Leupold’s 1-piece Standard A-Bolt base provides a secure, single-piece mounting platform for a Browning A-Bolt Right Hand Long Action and is intended for standard calibers less than .300 Win. Mag. The steel STD system is engineered to match STD 1-piece or 2-piece rings and bases so scope alignment and repeatable positioning are preserved.

• Front dovetail ring pivots to allow lateral adjustment using the rear windage screws while bore sighting, helping align the scope without altering elevation settings.
• STD rings are offered in five heights and accept shims, which lets you reserve the scope’s elevation travel for BDC (bullet-drop compensation) dial use.
• Constructed from Leupold steel and designed to work with the company’s mounting systems, the base is presented as rugged and dependable—matching the optics it secures.

Designed as a straightforward mounting solution where compatibility with Browning A-Bolt Right Hand Long Action and standard calibers under .300 Win. Mag. is required, this Leupold 1-piece base emphasizes repeatable alignment and scope adjustment options. The product information supplied notes it is made in the USA and described as guaranteed to hold up to a lifetime of abuse.
