Jaeger Precision shows the installation of the KPYK Ukrainian handguard unto a Tokyo Marui AKM GBBR. Initially, he encounters fitting issues because the handguard, intended for GHK and LCT models, requires significant modifications for the Marui AKM. These modifications include grinding down parts of the bracket, filing sections within the handguard, and removing the gas tube's "wings." Despite these adjustments, the installation is ultimately successful, providing a tight and solid fit and resulting in a noticeably longer replica with a unique, visible gas piston.
