The A-TEC CMM-4 rimfire/air rifle silencer is a compact, ultra-lightweight suppressor, designed for rimfire rifles and pistols up to .22 calibre and for air and CO2 weapons. Manufactured in Norway by A-TEC, the silencer is an all-aluminium modular unit. The A-TEC CMM-4 rimfire/air rifle silencer weighs only 105 grammes and adds only 129 mm net length to a typical rifle – and with a diameter of just 30 mm, it is slim enough to be used with lowmounted telescopic or iron sights.
A-TEC rimfire/air rifle silencers are available with ½"x20 UNF and 1/2" x 28 UNEF internal threads to fit directly onto a screw-cut rifle or pistol barrel.
The A-TEC CMM-4 rimfire/air rifle silencer reduces sound emissions by -24 to -35 dB(A) (depending on barrel length, calibre and ammunition type). With subsonic ammunition, the muzzle signature is usually much less than the noise of the bullet or pellet hitting the target. With high velocity rimfire ammunition (up to 17 HRM or 22 WRM), the A-TEC silencer substantially reduces the muzzle blast although no silencer can reduce the supersonic bullet flight noise. All rimfire rifles and pistols tested with the A-TEC rimfire/air rifle silencer comply with the latest personal noise exposure limit set by European Directive 2003/10/EC (140 Pa or 137 dB(C)).
For Rimfire, Rimfire Magnum and air weapons.
