Adapter plates by Calculated Kinetics are machined here in the USA from 6061 aluminum then hard anodized black to give you the durability to last a lifetime. All plates come with the hardware, Vibratite, and installation instructions to properly secure any Modified RMSc (407k/507k/EPS Carry). Calculated Kinetics recommend adding the Ameriglo GL453s as the OEM backup iron sights are barely useable. Different guns cycle at different rates and different forces. Some screws are thicker than others and hold optics and plates of different weights.
