Whisper (Magnum Silencer With Brake)


The SUS-TAC WHISPER MAGNUM is our flagship model. This design is a no compromise performance orientated suppressor. With the cone count increased by 40% over the standard version, this suppressor reduces sound pressure by an impressive 33+ dB(C). Recoil is also reduced by a staggering 52% making for a very pleasurable shooting experience.

Added to this is that any time the gun is not fired for approximately 5 to 10 minutes any suppressor will fill with fresh air (containing oxygen) and cause a “First Round Pop” or “FRP” to occur. Most silencer designs suffer from a FRP of up to 10 dB louder than subsequent shots. The advantage of this silencer is that it almost completely removes the “FRP” effect. This is important as this can effect the user in many situations such as when hunting or in shooting competitions between rounds as the FRP will in most cases not be hearing safe. Not with this suppressor!


The SUS-TAC MAGNUM Series Suppressors are a modular suppressor which has an integral Recoil Brake added to the front of it. The SUS-TAC Recoil Brake is a clever design as it reduces recoil significantly without increasing the dB reading. This has been tested numerous times and we found that this design does not increase the dB’s when compared to shooting without the recoil brake.

The larger volume selected along with the extremely efficient internal design used allows this suppressor to to maintain SUS-TAC’s high suppression standards with large calibers or calibers with high power loads, such as a .338 Lapua Mag, .375 CheyTac, .375 RUM and .458 WinMag to name a few.

SUS-TAC’s MAGNUM Series suppressors pass, and with the performance models even exceed, the US Military Specification for hearing safe operation (without any hearing protection) by up to as much as 10dB.

The SUS-TAC MAGNUM Series are non-reflex suppressors which attach to the end of the barrel with a screw thread. The units are available in virtually any thread.
