Product Description The Calculated Kinetics Glock 43X/48 MOS Adapter Plate is a precision-machined solution designed to seamlessly mount Holosun K footprint optics - including the 407K, 507K, and EPS Carry - onto your Glock 43X or Glock 48 MOS pistol. Crafted right here in the USA from 6061 aluminum and hard anodized black for lasting durability, this adapter plate features full recoil lugs for a secure fit and co-witnesses with OEM iron sights. Every plate ships complete with mounting hardware, Vibratite thread-locking compound, and a step-by-step installation card so you can get your optic running quickly and confidently. For those seeking improved backup sights, Calculated Kinetics recommends pairing this plate with the Ameriglo GL453s, as the factory OEM sights offer limited usability.
