DESCRIPTION

The Ase Utra NorthStar NS-3B suppressors are robust and effective suppressors designed for centre fire calibre rifles up to 9.3x66 Sako calibre.

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)).

* Suppressors can be used on these calibres, however the bullet channelis oversized compared to the calibre, possibly affecting suppressorperformance. Also the suppressor may be too short when compared to the power ofthe calibre.
** Safe to shoot, however the difference between the suppressor bulletchannel and calibre is quite excessive and clearly affecting the suppressorperformance.
