Take your pick, KeyMod or the Z-Series handguards from LCT Airsoft. With their modularize series, the company got a lot of handguards available for LCT AK AEG owners to choose from. They just need to consult the images included in this post to check the compatibility of their LCT AK AEGs before ordering. Too bad that some will be disappointed for the lack of M-Lok options.
