T-N.T APS-X Upgraded version T-Hop Buck for VIPER series

no more loose bucking! no more half way!

t-n.t. airsoft's hop up bucking will change your game forever!

with a patented unique design, t-n.t's hop up bucking will increase range and accuracy by creating an airtight vacume, thus eliminating the bb's "wiggle room" while waiting to be fired.

once the bb is fixed into position, it has no other way to go but streight....

in addition, t-n.t buckings have a specifaclly designed guide to direct the bb to the exact center, makeing it shoot exactly to the middle of the barrel.

not all airsoft guns are the same. that's why we have designed a specific hop up bucking to acommodate most kinds of airsoft guns such as aeg's gbb's kwa's ghk's and the newly addition to the t-n.t family, the mp7 gbb retrofit kit.
