CHPWS Defender Optic Plate for Holosun 407C / 507C / 508T fits Glock MOS

What is the V4 Series of Adapter Plates and Why?
 
The CHPWS V4 Series of adapter plates has evolved over the past five years because the OEM mounting plates are the weakest link in the Red Dot System.
 
The new V4 Series address two specific areas in the Red Dot Mounting:
Mounting Hardware
Optic & Lens Protection
 
All new V4 plates will feature our Patent Pending replaceable stainless steel T-Nuts and stainless steel Torx® head screws which are used to mount the RDS (Red Dot System) to the V4 plate giving you the ability to replace the mounting hardware without replacing the entire plate.
 
The V4 Series retains it’s industry leading six to seven full revolutions of thread engagement for maximum retention.
 
The second feature we are introducing is our Patent Pending Defender Window. The V4 Defender series of plates is made from a Proprietary Impact Resistant Polymer and will feature a protective window frame in front of your RDS.
 
This protective window feature serves several real-world purposes;
It protects the RDS from rugged use, abuse and frontal impacts in harsh conditions
It prevents the shooter from making contact with the lens during slide manipulation. In short, it protects your optic and keeps your sweaty palms off the glass so you can stop using your sweater T-Shirt to clean your front lens.
