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 BB bullet 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.
2. With 2-stage channel, the X-Range’s bell configuration is shallow to deep. BB bullet 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 BB bullet. 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 BB bullet that also prevents the rear section of the depressor from deforming. Friction against BB bullet drops dramatically when moved by air from the shallow to the deeper channel section, with BB bullet 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 1st Class aircraft 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 temperature as low as -60°C.
