Calculated Kinetics manufactures this adapter plate right here in the USA from 6061 aluminum, then applies a hard anodized black finish for durability that will serve you for decades. It's designed specifically to allow you to mount Holosun K-footprint optics—including the 407K, 507K, and EPS Carry models—onto your Glock 43X or 48 MOS pistol.
The plate comes ready to install with everything you need. Different firearms cycle at different rates and with different forces, which means screw tension matters. Vibratite helps ensure your optic stays put through thousands of rounds.
Calculated Kinetics recommends pairing this plate with quality backup iron sights, as the factory Glock sights can be difficult to use effectively with a mounted optic.
A quality adapter plate is the foundation of a reliable optics setup. This American-made solution gives you the confidence that your sight picture will remain consistent when it matters most.
