Retro Arms CNC Machined Aluminum Rotary Style Hop-Up Unit (M4)

By using superior quality components, the Retro Arms Hop-Up Chamber allows users to get the best possible performance out of their Airsoft AEGs. The Hop-Up Chamber has been CNC Machined from Alloy, resulting in a tough and exquisitely finished component. Combined with the precision manufactured Hop-Up Arm and the Polymer Radial Adjustment Wheel, this Hop-Up can be finely tuned and adjusted, allowing users to improve the range and accuracy performance of their AEG M4s and M16s.

As this Hop-Up is of the rotary Adjustment type, it is both incredibly simple to operate, and easy to use; the large, easy-access Radial wheel is possible to use even with gloves on. Installation of the Hop-Up is easy; the quality of the components allows them to fit together with little difficulty. A horizontal indent on the rear of the C-Clip helps users install it the correct way around. 

Features:

  • Compatible with most Airsoft M4 AEGs
  • Rotary style Hop-Up Unit
  • Precision CNC EN AW 7075 construction for extended lifespan
  • Easy to Operate with Gloves on
  • Incredibly precise and fine Hop-Up adjustment
  • Very Limited horizontal Arm wobble, enhancing performance
  • Easy installation
  • Enhanced Accuracy and Range

Package Includes: Hopup Unit and hardware (bucking and nub not included)

Manufacturer: Retro Arms

Special Instructions:

Please Note that this Hop-Up Chamber is not supplied with the Washer required to maintain the position of Hop-Up Arm during use. We would highly recommend re-using the relevant Washer from your Airsoft Gun's original Hop-Up Unit. 

The C-Clip for the Hop-Up Unit is designed to fit in only one way around to ease the installation. There is an indented horizontal line located at the top of the Clip; this must face Away from the Hop Up unit Chamber. 

The supplied O-Ring will not remain in place if simply rolled on; it must be stretched into position to stay in place.
