Looking for a reliable upgrade that improves handling of your AK’s charging handle? Need a larger and more secure grip for use with gloves or in bad weather? The RP-1 Charging Handle Extension by 5KU is a perfect solution. This bolt-on extension fits modern AK platforms and provides a wider, textured surface for faster and more confident operation. Made of CNC-machined aluminum, the RP-1 combines lightweight design with excellent strength. The textured face prevents slipping and makes it easier to rack the bolt — or access the hop-up chamber on AEG models. Installation is quick and simple: the extension slides onto the standard charging handle and secures with a hex screw. For maximum security, applying thread locker is recommended. The design closely follows the real ZenitCo RP-1 model.
