Old ver. HOP chamber - The​ wider HOP lever.

​

2. Prepare the aluminum sheet :
​width 1~2mm.

3. Slightly polished the protrusions and use adhesive to stick firmly fixed.

4. Adjust the lever's angle, so that HOP bucking dots can be averaged, then adjust the HOP-UP dots in the middle, then assemble, done!!

New ver. HOP chamber - ​The narrow ver. HOP lever.

1. Break up HOP-UP chamber.

​

2. Use Heat-Shrinkable Tube (about 3mm) to set into protrusions and heat it.

3. Adjust the HOP lever's angle like photo, so that HOP bucking dots can be averaged.

4. Try to increase the HOP-UP and set the dots in the middle. (The dots must be same size to avoid causing ballistic offset)

P.S. - If want to increase the effect of HOP-UP (to use heavier BB), you can adjust the angle like the photo (lever's feet in wheel).

5. Assemble, done!!
