Inner barrel 6,03/430mm APS-X Hop-Up System VSR H+ Kit for VSR - T-N.T.

T.N.T'S cutting edge inner barrels are definitely the best thing in airsoft today.
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 range by 30-50 percent!

how does it work?

T.N.T. inner barrels are uniquely designed from tight bore to wide bore.

Specially designed grooves will create an air cushion that will guide the bb while shooting out of the barrel eliminating the contact of the bb with the barrel's sides, and then making sure that that same air cushion will disperse out of the barrel before the bb is shot.

This will allow the bb shot from your airsoft gun to be untouched by that air bubble on exit, therefore eliminating the deviation usually created by it.
