The KVK is a rail mounted accessory that offsets the tactical pressure switch mounted on it at a more comfortable angle, offering a more natural grip without needing to adjust hand position on the rifle in order to activate the pressure switch. 

Compatible with all rail-mounted Zenit tactical pressure switches such as the KV-1, KV-1P, KV-2, KV-2P.
