【T-N.T. APS-X HOP-UP SYSTEM】PATENTED PRODUCT
H+ Precision Dual inner diameter Air-cushion inner barrel 

This product we name it "H+ Inner barrel" , was developed for most sniper rifles on the market, the entrance of the inner barrel can be directly installed with the full range of T-N.T. HOP-UP bucking, and corresponds to most HOP-UP bucking on the market.

H+ inner barrel outer diameter 9.95mm, after lots of shooting tests, the barrel wall is more thicker,  the overall shock resistance is more excellent, can make BB beating more stable before leaving the barrel, accuracy is relatively improved !! 

If upgrade to HS+ inner barrel can improve the stability of the trajectory, more improved ballistic stability, use with TR-HOP bucking and heavier BBs, you can feel a significant increase in accuracy !!

We believe this is one of the indispensable conditions for a sniper rifle, and even promoted to high-level top players are one of the necessary conditions !!
