Zenitco RP-4 Charging Handle Knob for AKS-74U
- $79
Available Options
In short: Zenitco RP-4 is a CNC-machined D16T aluminum enlarged charging handle knob for AKS-74U and configurations based on that platform. It measures 20 × 22 + 3 mm, weighs 14 ± 2 g and is secured with three supplied screws.
Compatibility
Compatible: AKS-74U and configurations based on it, using the standard charging-handle lever documented for RP-4.
Not compatible: Ten-19K. Its standard lever is wider and does not match the RP-4 interface. For other documented platform groups, compare RP-1, RP-2 and RP-3.
Purpose
RP-4 clamps around the original lever to create a larger, deeply ribbed contact surface. The two-part construction secures the knob without replacing internal components.
