Quality. Precision. Innovation. CATALOGUE 25 SUPPRESSORS ABOUT US B&T: SWISS MADE QUALITY, PRECISION AND INNOVATION. Over the past 30 years, a small company on the shores of Lake Thun, known to only business insiders, has grown into a small force in the industry. Despite growth and change, B&T has kept the most important thing with that it started more than thirty years ago. 3 That is, passion for firearms and creating high-precision solutions for the most demanding customers. B&T AG, a Swiss company with an excellent reputation as a specialist producer of carbines, submachine guns, suppressors and weapon accessories. B&T stands for quality, precision and innovation worldwide. 06 HISTORY 08 SUPPRESSOR BASICS 10 PISTOLS / SUBMACHINE GUNS 16 SERVICE RIFLE / MACHINE GUNS 26 HIGH ENDURANCE MATERIALS 28 HUNTING / PRECISION RIFLES 32 CUSTOM SOLUTIONS 34 CONTACT 5 PRINT-X RBS, HUB-INTERFACE, MG, SUPPRESSURE DUMMIES HISTORY HISTORY SUC (Squared Ultra Compact) – 9mm Pistol Suppressor.

However, these have become widely popular only over the last 20 years. During this time the requirements have changed in many ways. While suppressors were initially obscure tools for selected special applications, today these items are the primarily instruments for hearing protection and signature reduction. In order to make the actual effects of suppressors clear, some basic principles should be explained. SCHALLDÄMPFERGRUNDLAGEN When a bullet leaves the muzzle, there are always some combustible gases and unburned powder particles. When these elements come into contact with the oxygen in the ambient air, they ignite. The resulting muzzle flash can be significantly reduced using suppressors. Another ballistic phenomenon is when the bullet leaves the muzzle, it is overtaken by the combustion gases. This can destabilize the bullet during flight and reduce accuracy. By slowing down the gases, a suppressor can minimize this disruption to the bullet’s flight. The additional mass of the suppressor at the muzzle also reduces barrel vibrations, which can also have a positive effect on the overall accuracy. 9 SUPPRESSOR BASICS When a bullet leaves the barrel of a firearm, the gas pressure, equaling several hundreds to thousands of times atmospheric pressure, is suddenly equalized. This process is perceived by the human ear as a loud bang. To reduce it, suppressors restrict and slow the flow of the combustion gases at the muzzle. Another source of sound when a shot is fired is the sound of the bullet moving above the speed of sound. The final source of noise is the mechanical sound of the weapon’s bolt or slide. A suppressor cannot influence the acoustics of these final two actions. B&T also has suppressors that are integrated with barrel that are ported near the chamber. This will reduce the speed of 9mm bullets to such an extent that the sound of the bullet breaking the sound barrier does not occur. Suppressed bolt-action weapons when used with subsonic ammunition such as the SPR300 offer minimal noise because there is no mechanical or ballistic noise when fired. PISTOLS / SUBMACHINE GUNS PISTOLS / SUBMACHINE GUNS The passion of our founder and company owner Karl Brügger is pistol caliber carbines, especially in the 9 x 19 mm caliber. This is reflected not only in the large number of weapons that B&T offers in this caliber, but also in the associated suppressors. 11 To meet a variety of applications, B&T offers a wide range of suppressor for pistols, submachine guns and pistol caliber carbines.

This is due to their extensive use among police forces and modern armies alike. 17 The range of models, calibers, barrel lengths and operating systems found in modern service rifle designs contributes to the wide variety of products found in the B&T suppressors range. In addition to the various muzzle interfaces, there are different suppressor designs with different operating parameters for most calibers to choose from. In addition, B&T has recently developed the next generation suppressor. This is the RBS family of suppressor for automatic weapons. More about this on page 20.

Pressure Time Pressure The current generation Print-X RBS shows only 0 – 5 % increase in cadence and bolt velocity, depending on the weapon system. For comparison, the difference between the bolt velocities of clean and lubricated weapons versus dry, dirty weapons usually exceeds 10 %. Conventional suppressors reduce the muzzle blast by slowing down the combustion gases at the muzzle. As a result, they create a gas build-up. This leads to an increase of up to 30 % in the bolt velocity and rate of fire of self-loading weapons, especially gas-operated ones. A part of the pressure remains until the breech is opened, causing combustion gases to be blown through the ejection port towards the shooter. This phenomenon is called blowback. Time To reduce blowback, B&T has developed and patented the Reduced Backpressure System - RBS. In contrast to conventional suppressors, a part of the gases are channeled forward from the first chamber. As a result, the pressure drops significantly faster and considerably less gas reaches the shooter. A further advantage of the reduced back pressure is that the bolt velocity and rate of fire do not increase or only increase minimally depending on the weapon configuration. RBS suppressors can therefore also be used on weapons without an adjustable gas block without causing additional wear on the firearm. 21 REDUCED BACKPRESSURE SYSTEM When shooting unsuppressed, the gas pressure is suddenly equalised to atmospheric pressure at the muzzle. The resulting pressure wave is perceived as a loud bang. HUB-INTERFACE HUB-INTERFACE HUB QDN (Nato Birdcage) HUB QDM (M.A.R.S.) Muzzle Thread HUB QDSF (Surefire) HUB QDAU (Ase Utra) HUB DM (Direct Mount) 23 The HUB interface (Harmonised Universal Base) allows any combination of silencer bodies with adapters of all kinds. This means that a silencer can be used on different weapons with different muzzle interfaces. In addition to our own interfaces (NATO, M.A.R.S., QDR), B&T also offers solutions for direct mounting as well as interfaces for the most common silencers from AAC, Acheron, Ase Utra, A-Tec, Huxwrx, SIG, Surefire and others. SUPPRESSOR DUMMIES MARS QD TRAINING BLUE MARS QD TRAINING RED RBS QDN TRAINING PRINT-X RBS LMG PRINT-X RBS50 M2A1 Due to the enormous thermal influences, machine guns place the highest demands on suppressor designs and materials. B&T has accepted this challenge. The result is a range of suppressors that meet the highest requirement. In order to ensure the proper function of the weapon, B&T’s patented RBS technology is used. The calibers that are currently covered range from 5.56 mm (.223 Rem.) to 12.7 mm NATO (.50 BMG). SUPPRESSOR DUMMIES ROTEX V COMPACT TRAINING MG MG B&T offers a wide range of training suppressors and blast deflectors for all applications. This is regardless of whether it is mounted on an inert manipulation weapon, a blue gun for FX or UTM training ammunition or a live weapon, B&T has a training option. These products have no baffles and do not reduce sound. It will focus the energy directly forward of the shooter. These products correspond to the exact size and weight to the live counterparts and provide an excellent way for the most realistic training possible.

Inconel is a Nickel-alloy developed to keep its strength at very high temperatures (see diagram). It is also very hard which makes it hard and expensive to machine. It was previously used only in the most highly stressed area of assault rifle and machine gun suppressors the blast baffle. Using state of the art additive manufacturing however, suppressor bodies can now be completly ‘printed’ out of Inconel in a cost-effective manner. This allows the new generation of Print-X suppressors to surpass their predecessors impressive records by a wide margin. JAGD- / PRÄZISIONSGEWEHRE HUNTING / PRECISION RIFLES We expressly welcome and support this development.
