Sound Suppressors

[Geezer]

Having just waded into the airgun universe I wonder at these sound suppressors that are on many rifles these days. First of all, I live in a area where sound is not going to be a problem so I have little interest in having one of these on my rifle.

1. how do the suppressors affect the trajectory of the pellet?

2, How do the suppressors actually suppress the sound?

3. how is cleaning the barrel with a rod and a patch with the suppressor in place?

4. do any of you know how well they work?

I have not noticed any of the spring airguns with a suppressor you can remove if you don't want it. In fact most have the front sight built into the suppressor (if equipped with open sights).

I also notice that the rifles with the suppressors have a very short barrel. Does this affect the range of the rifle? I have always believed (I don't know why) that long range accuracy required a longer barrel. Some of these suppressors look really big; if it is on a rifle with open sights I would think the front sight might interfere with the scope sight picture.

In any case, I was just wondering about these things and know you all have forgot more about airguns than I will ever know, so I thought I would ask.

Here is your opportunity to "School" a old Geezer!

Yes they work to suppress the sound. Some so well in .177 and .22 that all you hear is the guns mechanism. You can clean the barrel but be care full pulling any patches through a silencer or shroud as it can disrupt the baffles inside. Silencers work by redirecting the air/sound away from the end of the barrel. Barrel length can but does not determine accuracy. This is a general response because you do not mention power plant or caliber, which determine much of how a silencer is made to attach to the gun and it's size

Geezer. I have a Donny FL Sumo on my Cricket Mini .22. It takes the report down to the proverbial “mouse fart” The suppressor is in .25 but works superbly well. It does affect trajectory, but it’s repeateable, meaning it will hit the same POI as long as it is on, changes if I take it off, but will hit same hole as long as it stays off. I’m able to just screw it off, then I clean my barrel, which is not very often. Hope this helps.

I clean mine with shroud on by inserting a drinking straw that is split up the middle, that way the.patch stays out of the baffles.

Once you start running suppressors there's no going back, Its like going from spring guns to pcp's, I have donnyfl's on my wildcat and taipan, I go out and shoot on the weekend when everyone's still asleep, they never hear me doing my thing.

In an empty room, pop a balloon. You will hear echo of the release of air pressure.

Now, put that balloon in a cardboard box with a small exit hole. Pop that balloon and you will notice a difference in the sound. The crack is muted to more of a thump. There in lies the effect of a moderator. Slow down that escaping air to minimize sound production.


Take a look at this video...
