In this video a Sonic 45 Compact silencer is subjected to a total of 80 shots of 7,62 (.308 Win). The smoke seen towards the end of the video is gas from each shot that leaks through the treads at a seem of two silencer cups. This is because the extreme heat of the ordeal has vaporized/combusted most of the sealant putty used in the assembly.
The Sonic 45 Compact handles the punishment far better than the Ghost 50*, due to both the innerpipe and the studs of the 45 Compact being made of stainless steel for durabillity, rather than aluminum as in the Ghost 50 for reduced weight.

Translation of the danish parts:
- Woah! Now it's starting to sound strange
- There's no more left (last magazine is empty)

This video is one of four short clips from a recent test of two of our silencers: the Ghost 50 and the Sonic 45 Compact.
The Ghost 50 is a new lightweight silencer made with an innertube of aluminum for maximal reduction in weight and is as such designed for moderate use, e.g. a few shots fired during hunting, due to the less resilient nature of aluminum.
The Sonic 45 Compact is in essence the same as a Sonic 45, the only difference is a significantly shorter extension over the barrel in order to accommodate rifles such as carbines.

In the test both silencers are each subjected to four magazines of twenty 7,62 (Cal .308 Win) shots from an M75 and four magazines with 10 + 30 + 30 + 30 shots of 5,56 from an M95
