Hey guys,
I see plenty of videos comparing the sound differences with barrel extenders attached on AEGs but haven't been as lucky with finding ones of GBBr's, specifically LM4's. Therefore if anyone out there is sporting a 5KU KAC QD extender I am very interested to hear the differences with it's attached and without to the LM4. Any replica KAC extender will do however not having to be the 5KU one. Thanks guys

Dino

While not KAC or the LM4, I have a comparison video on my YouTube page (geckoactual) with my MP7.

Nice you're gecko, love the vids!

I have a Magpul aac m-4 2000 which has the foam insert, it silences my aeg to a thump rather than a crack but didn't do much for the lm4.  I didn't notice any audible difference when firing...

Amplifiers kind of work with a gbbr..but foam filled barrel extensions dont really do any thing to suppress the sound of the gun firing..as the shooter you still hear the sound of the bolt going back and forth..as far as the business end of the gbbr..not sure..never paid attention to that..

Roger guys, thanks for the replies. I'll prob be picking up the KAC replica then for aesthetics then until I build a second upper with a longer inner barrel. Again thanks.

Like Boobie mentioned on the user end you'll barely notice a difference. I hardly noticed a difference until I made the videoand heard the difference for the people Im firing at.

I have that exact [barrel extension] and when I slapped it on it was not as noticeably quieter as when I had it on my 400fps 300mm tbb aeg.  Looking to sell it now since it doesn't do much and it makes the gun too front heavy for me.
