I have many brand new never opened kits for sale. These are VERY hard to find. I am asking $400 shipped. USA only.
This FX Impact Tensioned 800 mm barrel kit can be of great use when your M3 is used to shoot heavy slugs over long distances and comes with a Superior Heavy Liner. The increased amount of thrust that is needed to launch a slug over long distances can cause an increase in barrel oscillation, which can negatively alter your shot pattern. This tensioned barrel decreases these oscillations because it's more rigid and stiff compared to the original.
