Modify 65 ° X-Range GBB / VSR Hop Up Bucking / rubber (blue)
The X-Range Bucking from Modify for GBB and VSR models offers two special features:
- The rear diameter is made a bit narrower than other rubbers, which ensures a perfect seal to the nozzle
- The patch surface is chosen to be concave and uses the entire length of the barrel window from
We tested this bucking in three different backups, here we could reach a maximum range of up to 60m. (WE HiCapa - 0.92 Joule, 0.25g, GBB)
For VSR models from 2.0 joules and 0.30g + we recommend using the 70 ° version.
Attention:
These buckings only work on barrels with an OPEN hop-up window. Not suitable for WE GBBs with original barrel! A combination of rubber and tuning barrel is required here.
