sound moderator
Wondering whether sound moderators are necessary?

Well, if you want or need to reduce the amount of noise and visible muzzle flash your firearm or air gun generates when firing, then you will need to fit a suppressor or sound moderator.

Moderators are sometimes referred to as silencers, but this is misleading as you cannot completely silence the report of a high-velocity bullet.

When the rifle is fired, two sounds are heard if you are close to the passage of the bullet. The first is the supersonic crack of the bullet passing, followed by the thump of the rifle discharging that follows shortly afterwards. It is the latter that gives away the direction of the firer, and the time between the two sounds also gives the observer an indication of how far away the firer is.

Q: You would be surprised just how much of a crack an airgun can make — especially pre-charged models.

Keeping an airgun quiet is a great aid to stealth and helps…
