Leupold STD Two-Piece Scope Bases

Complete Leupold STD base set for use with Leupold or Redfield style rings.  These bases fit post-war model 70 rifles (serial number 66,350 and higher), except H&H magnum. These STD bases are available in 4 models: 50020 - Standard in gloss blued finish 50021 - Standard in matte black finish 50022 - Extended in gloss blued finish 50023 - Extended in matte black finish The STD "extended bases" can be used to accommodate scopes where the length of the tube between the objective and the eyepiece (dimension B in the Leupold diagram) is too short for the model 70 receiver. This is a common problem with adjustable power scopes due to the shorter tube length and the length of the pre-64 model 70 receiver. Most bases are new in the factory packaging. Any used bases have been graded in NRA excellent condition. We use the NRA Modern Gun Condition Standards Grading System for grading part conditions. You can read about it HERE
