Quiet BBMG

Unread postAuthor: Davidvaini » Wed Jul 22, 2009 12:37 pm

So I got an idea, a lot of people like to make their AEG's and other Airsoft guns quiet. It really helps to hid your position on the airsoft field and overall makes a more effective gun.

Now I always admired how quiet a BBMG is, but I got another idea on how to make it quieter.

I was thinking about lining the inside of the chamber that houses the vortex in a thin arts and crafts foam. It would not take up much space and would silence BBS from rattling inside the gun as well as BBS hitting the side wall.

That with a foam "suppressor" along the barrel to reduce the noise of the "TINGS" of the BBS flying through the barrel.(not an actual suppressor mind you.)

The main idea is to line the inside of the vortex chamber with this thing foam. I have used it in my Drum Magazine for my AK to reduce the noise of the BBs shaking around.

I was also thinking about making the vortex block or vortex cap or whatever it may be in some sort of silent material but I have not found a good silent material that doesn't have massive amounts of friction.

You'd also have to coat your BBs in foam to stop them rattling against eachother ;)

Not necessarily. Just stop the rattling noise from escaping the chamber.

actually once the foam is on the inside of the container the noise drops down enough where you cant hear anything past 5 feet.

My drum magazine is lined with the foam and it holds 2500 rounds and I can shake it pretty violently and you cant hear it at all.

The magazine was originally metal and was very loud. Even just moving it slightly would sound like a Rain maker.

So I would not have to line the BB's with foam lol...

Of course not, I was joking :) besides, they have to hurt when you shoot someone with them!

any suggestions on a vortex block/cap material that would drop noise but not increase friction?

Stick a roll of mousepad type foam inside?

We've (the paintball community) have been doing this with our hoppers for years. It really does cut the noise. We use felt for the most part.

As far as the vortex cap, isn't that usually inside the chamber? If that is the case, you could probably just insulate the outside portion of it to reduce the noise.

that was the original plan, im just curious to see if there is such a material that would work for the vortex block and that would seriously cut down noise.

Coat the vortex block in rubber? Or maybe even Plasti Dip?

With a tight bore barrel this shouldn't be an issue.

Perhaps paint on a thin layer or latex rubber.

Now slowing down the rate of fire should be another thing on your list of to dos. Nothing gives your location away more than a beam of bb's, firing in bursts help but a slower rate of fire of say 15-20 rps would be nice.

Simple solution - use black BBs, much harder to see.

Does that thing kinda look like a big cat to you?

[quote="jonnyboy"][/quote]

As I have made many BBMGs, and even came up with the vortex cap design, I know how to properly use one. Especially on the Airsoft field.

Even with a tightbore barrel you still get barrel noise whether it be a tink or a sliding or rubbing noise, especially when you have a high rate of fire. (I only use good barrels in all of the BBMG's I have made)

Now slowing down a rate of fire is not a bad idea, but doing it by adding friction to the vortex block or cap would be a bad idea. As vortex BBMGs supply constant air slowing down the ROF via friction would increase the chance of Air going out without pushing a BB.

As I am in the united states I can buy bulk amounts of BBs for less, a lower ROF is not necessarily all that beneficial in a vortex based BBMG especially if its going to hurt the efficiency.

Now ideally I would want an application that is more efficient then a BBMG with a lower Rate of Fire.

I would also install a hopup into the BBMG which causes noise when the BB's go through. Having the Foam around that would also help reduce noise.
