  • Hi.
    So I have a Cz 452 Farewell edition
    And I purchased your Scope Base 20MOA Picatinny.
    Package # 103566-BLK
    The stamp mark on the Base is #103561-A
    MDT CZ 452
    It don’t fit it’s too small for the Dovetail .
    Is there different product #for this Rifle
    European vs USA size?

  • We build our rails to the 11MM dovetail size, so you likely have a 3/8 receiver one and our rails will not fit. 

  • Put a 30moa rail on my 457. Torqued the mounting bolts to 15 inlb as per your website Torqued them again to ensure proper torque. As i torqued one of the bolts the second time the bolt broke. Can you tell me what size bolt i need for replacement. Thank you
