Swiss Arms 53x32mm Sound Amplifier (14mm CCW)
The addition of a silencer/suppressor is something that many want to do to their replicas, however it can be confusing as to which silencer to choose from, given that there are so many on the market. It helps to first understand what gun you're putting the silencer/suppressor onto, as that will tell you if you need an adapter or not (e.g. G&P guns use 14mm CW threads, so would need a CW to CCW thread adapter) and you can go from there. Once you've established a pool of silencers that will go on your chosen replica, then it's a matter of whittling down the list based on the following: 1.) Look - no point in using it if it doesn't look cool, 2.) Function - what function do you require? Are you looking for suppression, a tracer, or a barrel extension? Barrel extensions are the cheapest, followed by the more effective suppressors, with the most expensive being the tracer silencers, and 3.) Aesthetics of the gun - if a silencer/suppressor doesn't match the proporitions of the gun, it just looks sort of odd i.e. pistol sized silencer on a sniper rifle won't be a match made in heaven!
This particular item is an amplifier, and closer to a flash hider than a silencer or barrel extension. Due to its conical design, this attachment enhances and amplifies any noise emanating from the barrel, so the noise from the piston head hitting the cylinder head in an AEG, or the gas propulsion/expansion from a GBB. These are completely unsuitable for use as a barrel extension due to being open-ended - they are only for use on guns where you want to add a little extra bang!
