Sliencer upgrade on m4
 

Thanks for all your advices. I am planning to get the following m4.

KWA M4 S-System

But I am planning to get a decent silencer in the hope of covering most of the front gun barrel like the following picture

Are there any silencers that could cover most of the front barrel? Or would I need to replace the front barrel with a shorter barrel so I can attach a silencer like the above picture??

You would need to switch to a 10.3" outer barrel, in order to get that connection point.

Or get an over barrel silencer.

Do you have a link to one? I haven't seen one before, so I'm curious as to how they mount. Is it a threading in the middle of the silencer?

I THINK that overbarrel silencers attach to the flash hider, or a notch behind it. I'm fairly sure that's how it works on RS, not really positive about on airsoft.

There are outer barrels that have threading right in front of the front site just like in that picture.. I have one on my rifle, really makes my setup unique because I change inner barrels and just stick a short silencer on the front. Then add the barrel back on for longer range at will.

Fdgfs, was thinking of QD (quick detach) supressors.

Yup, like I mentioned above, 10.3" barrel ends right after the triangle sight.
