Have you ever wanted to cut that pesky inner barrel down to proper size? Well, now you can!
I've been meaning to post this for a while now. This here is my Echo1 P90 that has been highly upgraded.
Enjoy!
Also, new logo! :D

Music is not mine, it is by Overwerk; the song is called Paradigm

huh, been thinking about doing this for my 516 (friend has a left over barrel thats a tad too long) i'm glad to know its not as complicated a process as I thought, THANKS!

[@hyperslow556gungamer]

Watched old vids from Japanese techs from over a decade ago, they say to cut the inner-barrel so that it sits inside the outer barrel about 1cm back from the exit port. This is to create a cushion of air around the BB as it leaves the barrel, helping stabilize the backspin. Similar to how Maple Leaf Crazy Jet works. Is there some physics truth to this?

[@chrispfeiffer1575]

I read somewhere that paper towel causes micro scratches in your barrel, maybe just for brass? I don't know if this is true or not, I personally use cut up microfiber cloth because it cleans nice!

[@TheAirsoftTech]

It doesn't really. I've used paper towels forever. Of course, micro fiber is way better.

[@unfussylobster]

Great videos. Keep it up! I would love to see a video on how and why people short stroke gears and pistons. Im still new and i find myself watching your videos for my sorce of info. Thanks.

[@TheAirsoftTech]

Sounds like a good topic for a video!

[@unfussylobster]

TheAirsoftTech also I freaking love your intro song haha.

You can use a metal lathe to do it if you/your dad's garage or if you know someone that has one, doing it on a lathe like i did will end up just like buying one brand new, it will give you a perfect crowining on the inside if you do it right :)

[@poopenshnapples7160]

Awesome video! Thank you for the guide

[@markwallace1251]

MasterClass.....

[@Vanish_1991]

Is it ok to cut the barrel of a G&G CM16 Carbine? I would prefer a short barrel but would it hurt the functionality?

[@eugeneiaclayton1304]

I use a small metal lathe for cutting and crowning

[@niels12321]

Can you tell me what pipe cutters you are using, can't find any around here with a crowning tool

[@Dominator775]

do you have to crown your barrel? it doesnt seem necessary

[@AgentMo]

Its absolutely essential. Without crowning it, the bb wont even fit through the tip. The cutting process makes the cutting point flare inward quite a bit

[@ianmathiesen2416]

Thx i actually need to cut a barrel i was going to get smaller one

[@jasonperez2024]

How do you make an AEG quiet?? Just got my JG Works M4 up and running and its pretty loud...

[@lennyswagmaster6567]

shim it correct AoE with sorbo, use a silent piston head, and maybe a silnet cylinder head

[@lennyswagmaster6567]

silent*

[@cami-vs3of]

you can tell by his question that hes not going to know anything of what you just said haha

[@BBTechAirsoft]

Do you have to sand the crown or polish with grinding paste? Or just leave it as it is?

[@jacksonporter1393]

BB Tech I can only assume good things come out of the extra work involved. I’d use brasso; something not too abrasive

[@lincoln668]

thanks very informative :D

[@XxJailbreakHelpZxX]

how do i find that exact pip cutter?

[@ciscomartinez4709]

Does the barrel go right onto the end of the drill like a bit?

[@skrimper]

No?

[@G20vtr]

Yes, i know, the video has 8 years old, but your barrell It was not too long to cut, just putting the flash hider on it was enough to cover the excess.

[@LuckY_AlviN]

Wouldn't work with a tracer unit

[@agogeairsoft5349]

Can someone direct me where i can find a pipe cutter like in the video with the crowning tool attached?

[@Natsukiyaa]

basically any hardware store should have them.

"Take some alcohol, 100%" but he has 50% xD

[@spoonkapeezi3408]

is there any risk in damaging the barrel by putting it in the drill? it seems like drill clamps on it right where the bucking goes

[@PanagsAirsoft]

Would this affect the accuracy at all? Also, Couldn't you use the drill for the pipe cutter?

[@Shveet]

implying you use a regular 6.03 - and you are only cutting an inch or two - you might notice a small difference. but if you are accustomed to a 30 inch barrel and shortening it to 8inches. yes there will be a huge difference. if i recall correctly 6.01 tight bore barrels are actually 6.03 at the feed end and 6.01 at the other, cutting a section of a 6.01 might show a significant change

[@Thrillowatt]

@@Shveet what about a 6.00

[@hicapasforlifeyeet4391]

Barrel length doesn't matter.....

[@skrimper]

@@hicapasforlifeyeet4391 not true, once you get around 350+mm it certainly does matter. It's all about that air volume

[@hicapasforlifeyeet4391]

@@skrimper I was saying that barrel length doesn't affect accuracy

[@arcinvert]

i guess it is kind a late but how long did the pipe cutter part take up?

[@AgentMo]

It takes like 3 mins for brass, but a little more for steel

[@RogueSystem087]

awesome video, make even 'how to....' please!!!

[@setho1231]

Hand drills are like airsoft barrel lathes

[@TheAirsoftTech]

Yayz Whoohoo Indeed, but I have a real lathe, too ;P
