homemade slincers

shane_rafferty

i'v heard of a few people having these and was just wondring

(1.) how there made ?

(2.) do they work ?

thanks shane:D

1) With a lathe and/or milling machine, and a fair amount of skill.

2) No.

For real steel as far as I know the making of a silencer may be against the law, but I have not clue how that translates into making one for airsoft through Irish Laws.

If you have watched undersiege or shooter there are scenes
where the "hero" somehow straps an Plastic bottle over the muzzle of their gun and magically makes a silencer out of them. In reality it actually can work!! :D
seen youtube videos before with real steel measuring sound levels using a plastic bottle silencer/moderator/supressor.

In airsoft terms there was a company before that offered
an adapter ring that allowed you to put the adapter on your airsoft gun barrell and it was treaded to accept your typical 2l Plastic bottle thread thats on the neck of the bottle.

This allowed you to produce both a silencer or an amplifier
from a plastic bottle.

If you wanted a silencer you put the bottle with a hole in it
to allow the bb to travel through its trajectory and the bottle would muffle the sound.

If you wanted an amplifier you simply cut the bottle
so when you fire the shot the sound from the AEG or GBB
was exagerated.

Sorry I cant find the link at the moment for the product but
if I do I will send it on.

The Moderator/Silencer (whatever you want to call it) on my Real Rifle looks like this on the inside:
it consists of an outer hollow cylinder that covers an inner threaded series of baffles or holes drilled
into an inner cylinder and you guessed it a Real Steel Silencer cost me about 40 euros
yet some Airsoft Fake Silencers cost more than the real thing! does not make sense Grrrr!



Although I have no experiance with "hearing" the difference an airsoft silencer makes
I cant help but feel its an awful load of bollox and that it could be down to more
imgaination and want rather than anything fact based and practical when it comes
to running about a forrest or airsoft venue. My personal opinion on airsoft silencers
is they are more for Looks/show rather than practical use.

Machined one out of a 35 or 40mm billet of aluminium just for the craic months ago, it's lying around somewhere, will take a few pics of it. Weighs a ton though and has to be friction fitted onto the barrel by means of a grub screw.

thanks lads just heard of a few people doin them was wondring if it was hard
think spend 30 something (in MIA) for something just for look :L
but thats just me bein cheap ha thanks lads

If you want one that works, Madbull worked with Gemtech (real suppressor manufacturer) a few years ago and developed the nearest thing to an operational suppressor as they could.
I've got the Gemtech HALO and G5, and the Quicksilver (different RS manufacturer, same system as the others though).
The HALO is, unarguably, the most effective, but the Quicksilver is fantastic on my P90. Astonishingly so. The G5 sits on my M7 and does make a difference, though not as much as the other two.

All other airsoft suppressors are basically just a tube with some sparse foam. Only useful for looks, or if you want a less conspicuous barrel extension for a longer inner barrel. They do nothing for the sound.

i have one of these madbull gemtech's on one of my m4's and it works great,really does work on semi auto,very hard to be heard within 15ft,however when i put it onto a different gun it does nothing

It's quite dependent on the design of the receiver.

Suppressors in airsoft work in a vastly different way to those in real steel. Essentially, an airsoft suppressor deals with acoustics. It's internal construction is designed to dampen high end sound. This is usually sufficient, since it's the high-end "snap" noise of the piston slamming home that is the easiest to locate when heard in open air. Conversely, the dull, low-end "thud" sound, also produced, is harder to pinpoint in the open, but will travel further.

In real steel, it's vastly different, and has a lot more to do with air velocity and pressure changes. Not something we need to go into, though.

Basically, this all means how effective your silencer is, is determined by the gun you use it on.
A considerable portion of the sound comes from the barrel. The sound is carried down the barrel as the bb is fired. Suppressors can deal with this sound.
That said, the majority of the sound comes from the body around the gearbox, and the motor itself. Bullpup rifles tend to deal with this sound most efficiently due to their design and gearbox position. Build material also plays a factor. Something as simple as whether your hop cover is open can make a big difference.

Spotted a few different brands, have not got a clue how effective they
are. With reducing the noise from an AEG.

Have fitted a few silent piston/cylinder head sets and yes they do work in reducing the "THUD" from the gearbox
I would not call it silent but they do reduce the overall noise by better then 50% and in some cases by almost 75%
In the field you still may be able to hear the AEG fire but it is a lot harder to detect the exact direction it is coming from

NakedDex

I've considered those, but heard few reports of how effective they are. What brand did you use?

I have used both Systema and Elements
The systema was part of a Bore-up kit and is fitted in a 9mm V2 gearbox as part of a build for my own use
One of the Element ones was also a Bore-up kit and went into a 7mm V3 gearbox in a JG AK47
I also fitted a standard silent piston head/cylinder head to both a JG MP5 SD6 and a JG AUG these had the most reduction in sound deading
The first 2 had metal bodies and as metal will transmit sound better then the ABS body of the MP5 and the AUG
I was most suprised with the AUG as your ear is right against the body with the gearbox just inside

I should say that these were fitted as part of an upgrade and had bearings fitted and shimmed which helps in the smooth running and overall quietness of the box, but the most reduction in noise was in reducing the noise from the impact of the piston against the cylinder head
