5KU RP-1 AK Enlarged Bolt Handle Knob

5KU RP-1 Enlarged Charging Handle Extension for AK

The 5KU RP-1 Charging Handle Extension is a must-have upgrade for AK-style airsoft rifles, designed to improve weapon manipulation speed and control in any condition. Inspired by the real ZenitCo RP-1, this enlarged charging handle provides a wider, textured gripping surface for faster and more confident operation—especially when wearing gloves or playing in adverse weather.

Crafted from CNC-machined aluminum, the RP-1 combines lightweight construction with excellent durability. Whether you're running an AEG or GBB AK platform, this upgrade enhances both functionality and the aggressive tactical look of your rifle.

Key Features

• Enlarged Charging Surface: wider grip allows faster bolt manipulation and easier hop-up access on AEGs.
• Anti-Slip Texture: textured face ensures maximum control even in wet or muddy conditions.
• CNC Aluminum Construction: lightweight, strong, and built for long-term use.
• Quick Installation: slides onto the standard charging handle and secures with a hex screw.
• ZenitCo-Inspired Design: modern tactical aesthetic for AK builds.

This upgrade is ideal for players who demand faster weapon manipulation during CQB, milsim, or outdoor skirmishes. It significantly improves ergonomics and usability without requiring complex modifications.
