DESCRIPTION

Manufactured in Finland by Ase Utra Oy, the NorthStar NS-3B suppressors are all-steel, welded units rated for hunting, sport shooting or professional use onbolt-action or semi-automatic weapons.

The standard NorthStar NS-3B suppressors add 660-700grams net weight and 100 mm net length to a typical rifle – and with a max. diameter of 47.5 mm.

The NorthStar NS-3B suppressors are available with a variety of internal threads to fit directly onto the rifle barrel. Standard threads include; M14x1, M17x1,M18x1, ½"x20 UNF, to fit most current centrefire rifles.

PERFORMANCE

The NorthStar NS-3B suppressors reduce the weaponsound pressure level by 25-28 dB (depending on calibre and ammunition type), and significantlyreduces recoil and muzzle flash. The result is a weapon firing full power ammunition, with a muzzle signature lowerthan that of an unsuppressed .22 rimfire rifle. All standard rifles tested with the NorthStarsuppressors comply with the latest personal noise exposure limit set by European Directive 2003/10/EC (140 Pa or137 dB(C)).
