Using state of the art engineering, T-N.T. has designed a new kind of barrel, that will not only improve accuracy, but improve performance and effect range by 30~50% !! Key Feature : ●Enlarged HOP-UP window for bucking : Different from the common AEG or GBB inner barrel, the enlarged window is compatible with almost any brand of bucking.
●Air-cushion design : An inner barrel has two different inner diameters (6.03 ~ 6.35mm), the main purpose is to allow the high-pressure gas behind the BB to completely cover the BB, when the BBs is shot out of the barrel, since the high-pressure gas flow behind the BB is faster than the BBs, so it can achieve "Front guide" when the BBs shooting out.
●Highly compatible : T-N.T. inner barrel series is common platform, has been pre-completed with the side cut groove of AEG, GBB, and VSR, suitable the almost HOP-UP bucking on the market. More better compatibility, almost suitable for most popular brands airsoft replica model on the market.
T-N.T cutting edge inner barrels are definitely the best thing in airsoft today, use the『Precision Double I/D Air-cushion inner barrel』with『T-HOP / TR-HOP bucking』,make your airsoft BB gun's performance better then better !!
Material : bronze with electroplated chemical nickel surface. Inside diameter : 6.03mm (tight bore) ~ 6.35mm (wider bore), two different inner diameter in one barrel. Outside diameter : 8.5mm
【Each brand /gun type - inner barrel length list】 Common size conversion : 10.5"....265mm 11".......275mm 12.5"....320mm 14.5"....370mm 16".......407mm 18".......455mm 20".......510mm
※短內管無氣墊槽設計※ ※Shorter barrel have no Air-cushion design (Shorter than 220mm)※
因為內管太短氣墊效應不明顯,所以220mm以下的精密管無氣墊槽設計。 Because the inner barrel is too short and the air cushion effect is not obvious, inner barrels below 220mm have no air cushion groove design.
※精密管材質:青銅,表面電鍍化學鎳。 ※Inner barrel material: bronze&electroplated chemical nickel.
