DetailsTanio Koba Hop Twist Barrel 363mm
The Tanio Koba Hop Twist Inner Barrel Series uses a unique rifled inner barrel to create a vortex pocket of air around the BB as it fires. Rather than contacting the BB to create a horizontal spin, like with a standard firearm barrel, the Rifling creates a spinning pocket of air that works with the hop up to create stability and accuracy over a greater distance. The ideal velocity for this system is in the 310 to 350 FPS range. Higher pressures may see deminished results.
