This upgrade kit by GHK is designed for the GHK Glock MOS V1 series. The kit is to upgrade the older V1 system to the new and updated V2 system. The upgrade pack features a new V2 TDC (Top Dead Center) adjustable hop-up chamber set for a more consistent hop-up performance, a V2 trigger pack and striker control system which addresses the tough-to-defeat V1 trigger problem, decreasing the 2.5kg trigger pull of the V1 to a 2kg trigger pull while increasing the durability of the SCS, a V2 gas output valve for more consistent gas output per shot. Please do note that it is required to have DIY skills to properly install the upgrade kit, and it is recommended by GHK to use the entire GHK Glock V2 kit for optimal performance.
