FX IMPACT Barrel Tensioner KIT 700mm with Front Support

This FX Impact 700 mm Tensioner kit with Front Support replaces the original shroud of your M3 and provides reinforcement of the barrel, which is necessary when heavy slugs are being shot with increased power, when reaching for longer distances.

This reinforcement prevents barrel oscillation during a shot, which provides more accuracy and consistent results.

The Tensioner kit can be used on 700 mm STX barrels and comes with a Front Support, for M3’s that have not yet been fitted with one.

Your moderator can be put right back on the ½ UNF (M18x1 for 9 mm/.35) muzzle thread again after installation.
