So what's the latest from LCT Airsoft's Modularize series? For those who want the nice wooden look on their LCT AK AEGs can choose from three handguards depending on the model they have which cover the LCK-74, LCKM, and LCK-104 with an option of giving the LCKM with a more vintage look. Another is the availability of steel receivers that come with or without the side mount for optics designed for AK models.
