The KNS precision adjustable gas piston system for VEPR revolutionizes your AK's performance by offering precise control over the gas system, ensuring a smoother and more enjoyable shooting experience. This innovative system can be installed in approximately 10 minutes without the need for extensive gunsmithing or permanent modifications, making it accessible for all skill levels. It provides a versatile range of adjustments to accommodate both suppressed and unsuppressed shooting scenarios. Crafted from corrosion-resistant stainless steel and finished with a robust phosphate coating, this gas piston system is engineered for durability and longevity. Its low friction design ensures easy maintenance and cleaning, allowing you to focus more on shooting and less on upkeep. Please note that installation requires drilling through the Op-Rod after securing the piston into the carrier, due to variations in staking locations. The Op-Rod is specifically phosphated instead of nitride to facilitate this drilling process, ensuring a seamless installation experience. Adjustment without the need for tools Minimizes recoil Optimize nearly any AK for use with a suppressor Reduce the cyclic rate for fully automatic fire Manufactured in specialized facilities, 922R compliance component Piston head assembly constructed from corrosion-resistant stainless steel All surface components are nitride for enhanced durability Operation characterized by low friction and ease of cleaning
