Learn more about 5KU ®

5KU was founded in 2006 in Taiwan as a division of APS Limited, focused specifically on CNC-machined aluminum and steel upgrade parts — barrels, flash hiders, hop-up units, handguards, and folding stocks — rather than complete replicas. Their specialty has always leaned heavily toward AK platform upgrades, though most of their catalog is compatible across a wide range of AEG and GBB platforms, not just AKs. Because 5KU manufactures rather than outsources their CNC work, they've built a reputation as a reliable, affordable alternative to premium external parts brands, without sacrificing the fit and finish players expect from a metal upgrade.
