New MODIFY X-Range Hop Up Bucking for GBB/ VSR-10

Modify  has successfully produced the most desirable HopUp bucking for snipers and Mk23 fans. The new bucking has a lot of new and interesting additions. And that is made by Modify the company that in my opinion has the best quality control and consistently produces best upgrades for us airsoft snipers says a lot. Cant wait to get one for my King Arms sniper rifle.

Some features of the X-Range Hop Up Bucking for GBB/ VSR-10 (70 DEG.)

  • Two Hardness Options
  • Special Airtight Design
  • Bi-Point Design
  • Superior Tear Resistance
  • Excellent Temperature Properties
  • High Abrasion Resistance

The X-Range has the remarkable feature of depressor as seen in ZED of the popular video game League of Legends.

With large area in the front end to effectively cover BBs and twin-point design in the back end to centrally position BBs, the two features combine to achieve maximum range.


X-Ranges, and how they affect your accuracy and shooting range

The X-Range design was inspired by the R-hop, with the goal of maximizing contact with BBs when the bucking is depressed. That increases friction to produce top spin as well as air seal inside the barrel to achieve maximum range.

  1. The X-Range is bell- or cup-shaped with the wider end facing the loading nozzle.

With 2-stage channel, the X-Range’s bell configuration is shallow to deep. BBs are loaded into the shallow, narrow end to move to the mid-section where it is deeper and wider. Such channel configuration assures perfect BB positioning to also produce top spin to result in accurate trajectory. The shallow channel end of the loading nozzle widens when the bucking is depressed, increasing contact, friction with BBs. The bell opening has “wings” on either sides to form a bridge to the inner barrel window, being a solid, wide structure at the inner barrel entry to hold BBs that also prevents the rear section of the depressor from deforming. Friction against BBs drops dramatically when moved by air from the shallow to the deeper channel section, with BBs pushed straight along the channel by air to the bottom of the bell to enter the inner barrel with continuing top spin.





The X-Range is made of silicone material to be especially tough, resistant to wear and extreme temperatures, which reduce deterioration of the bucking. Even when using GBB,the X-Range keeps the hop-up working in low temperature.
