The Ase Utra jet-Z™ COMPACT is a high-performance suppressor designed for centrefire rifles up to .300 Win Mag calibre.(using .30 Cal model) Manufactured in Finland by Ase Utra OY, the jet-Z™ COMPACT suppressors incorporate Ase Utra's patented jet-Z™ baffle system. The jet-Z™ COMPACT suppressors are all-steel, all-welded units rated for hunting, sport shooting or professional use on bolt-action or semi-automatic weapons. The jet-Z™ COMPACT suppressor adds only 493 to 514grams net weight and 155 mm net length to a typical rifle – and with a diameter of just 40mm, the suppressor is slim enough to be used with low mounted telescopic or iron sights. The jet-Z™ COMPACT suppressors are available with avariety of metric and inch size threads to fit directly onto the rifle barrel. Standard threads include for example; M14x1, M15x1, M17x1, M18x1, ½"x20 UNF, ½"x28 UNEF to fit most current centrefire rifles. PERFORMANCE The jet-Z™ COMPACT suppressor reduces the weapon sound pressure level by 25 to 32 dB (depending on ammunition type, calibre, measurement location etc.), and significantly reduces recoil and muzzle flash.The result is a weapon firing full power ammunition, with a muzzle signature lower than that of an unsuppressed .22 rimfire rifle. All standard rifles tested with the jet-Z™ COMPACT suppressors comply with the latest personal noise exposure limit set by European Directive 2003/10/EC(140 Pa or 137 dB(C)).
