I know how to build them, but is there a specific place on the barrel i should put it, and are you SURE it doesn't lose any muzzle velocity or overall energy?

Also, does it matter where the spark is inside of your chamber?

for one- the silencer should be from the end of the barrel to where ever you want it to go to. obviusly the longer it is the quieter it will make it. and second- the spark should be closer to the back of the chamber. or even better make a spark strip that goes all along the chamber

having the spark at the back of the chamber will make it louder. yer a spark strip would be ideal. and if ya really want the best performance put the spark in the middle of the chamber.

do some research and ya would have found your answers.

thanks. but does the silencer slow down the projectile at all?

dude... silencers and supressors ABSORB and slow down the expanding gas out the muzzle. and since the projectile is getting its energy from this expanding gas... it would be obvious that there is a decrease on mv... i suggest looking into HOW things work... instead of building em blind.

GL mate.

silencers don't neccesarily slow down a projectile, indeed there are many cases in firearms where the addition of a silencer actually enhances muzzle velocity, as the projectile is under the influence of propellant gasses for a longer period.

This however doesn't apply to particular firearms like the MP5SD where there are deliberate design features intended to slow supersonic cartridges like the 9x19mm luger to subsonic velocities.

there are 2 systems to decrease the muzzle velocity of a bullet. the first one is the explosive expansion of the gas once the bullet leaves the barrel. the second one is the speed of the bullet. most effective silencers have a system to absorb the excess gasses and release them slowly, which shouldn't decrease MV by much at all. some other silencers also have things called "wipes" which the bullet hits, thus slowing it down, and eliminating the "sonic boom effect" depending on the size and velocity/load of the bullet, it can be silenced to literally silence. technically, the proper term for something without wipes is a supressor, becasue it is impossible to completley silence a firearm on gas absorption alone. so the basic idea, which can be found Here,http://www.advancedspuds.com/silencer.htm is what you should use, but possibly move the silencer out to the end of the barrel[/url]

I know how it works. i'm not dumb. But other people who have made them state that they notice no energy dissipation as a result of adding a silencer. thats why I am asking before I build and screw up my barrel.

a silencer will not decreas the velocity of the projectile

ok, i havent been back here for a while so i dont know you guys too well, i figured id just post what i know

Where do you get that?
Have you chronied it personally?
I don't think so.

no i have no chronied it personally
but even if there was a decrease it would not even be noticable
so unless you can prove to me that it does reduce the velocity i will think that it doesn't

It depends on how you're going to make your silencer. If you're going to make holes in your existing barrel and build an integral device, then it will likely reduce the velocity. However if you fit a silencer as an add-on, there will probably be either no effect on velocity or potentially a slight increase, have a look at the chrony readings at the end of this:

http://en.wikipedia.org/wiki/Suppressor wrote:One solution is to lower the muzzle velocity of the bullet. Some suppressor designs do this by allowing gas to bleed out of the barrel before the projectile exits; others do it with rubber "wipes" that use friction to slow the bullet. While this method is effective, it dramatically reduces the range, accuracy, and stopping power of the projectile. The wipes generally wear out and lose effectiveness after relatively few shots.

its on wiki so it must be true

That only applies to projectiles that are inherrently supersonic like the 9x19mm pistol round. If a bullet is already subsonic, like the 45 ACP, then you'll get no audible advantage from slowing it down further.
