A-Tec Silencers
27 Sep 2017


Latest News

A-Tec silencers are now available in South Africa. Whilst several sound suppressors are available locally, prices and quality also range considerably. This Norwegian manufacturer aims to provide the best suppressor money can buy at a realistic price.

A key feature of the A-Tec designs is that they are lightweight and not unduly cumbersome in size. A-Tec silencers are constructed from a high tensile aircraft grade anodized aluminum alloy (7075-T6 and 6082-T6) with stainless steel sections for longevity and overall integrity.

These silencers can also be field stripped to ensure proper maintenance and cleaning. The A-Tec design allows for complete component disassembly, a great feature for general cleaning and maintenance.  The manual states that cleaning should performed for every 200 rounds, but more regular cleaning wouldn’t hurt.

Due to the modular design a variety of internal muzzle threads can be catered for including most metric and Imperial sizes, or on request the threaded section can be ordered blank and only pilot bored, so a qualified gunsmith can match the thread to a specific rifle as required.

The overall finish both inside and out is hard black anodizing that is corrosion resistant.

The internal design is unique and has a gas cooling multi chamber interior. The A-Tec has a rear removable ‘over-the-barrel’ section that unscrews from the outer cover. The forward section houses the stainless threaded core that fits to the rfile’s muzzle. This section is removable to change thread sizes. Immediately forward of this is an aluminium spacer ring that forms a primary expansion chamber prior to the stainless steel baffle. This is a unique truncated volcano (hollow cone) design that redirects the initial blast backwards into the rear expansion ‘over-the-barrel’ section before re-entry into the baffle stack. This stack comprises of a series of four units identical in design to the truncated cone primary baffle. Each baffle maximizes internal volume for gasses to expand and each baffle has gas flow-ways and two holes to allow ingress and maximum gas flow retardation.

All A-Tec moderators comply with the latest noise exposure limit regulations set by the European Directive 2003/10/EC at 140pa or 137dB(c) noise level.
