Designed specifically for the ASG Scorpion Evo 3 A1 upgrade the existing adjustment wheel for easier and precise Hop-up adjustments.

• Redesigned Hop-up gear to enable micro-adjusting for the best hop setting depending on BB weight!
• Newly increased adjustment knob
• Adjust the hop-up even with gloves on and no need to carry an Allen key around the field to adjust
• Stronger gear system to keep hop-dial in place
• Give a fresh aggressive look to your Scorpion Evo
• Made of strong fiberglass nylon

The EHG has been tested by a whole variety of recommended batteries including the 1500Mah ASG stick type, AK long batteries, and 3 part nunchucks without affecting the adjustment wheel.
