The most quiestest barrel

[jerryjjackson69]

I always felt like Carbonfiber bores felt "louder", like they resonated a tiny bit more, but I do love how light they are. That just how my ear picks them up, I know lots of people feel like they are quieter.

[Chuck E Ducky]

I always felt the same way. I found they were worse then a lot of stock barrels. Never liked CF barrels. I have a Dye back that’s CF wrapped but the bore is stainless.

Ditto. In my experience, carbon fiber barrels resonated differently, and at a frequencies that made them seem louder to me.

The quietest barrel I have used has been the second gen powerlyte scepter with the proper sized bore. The small ports do a great job of releasing the gas in a controlled manner and always made my lvl 7 classic mag or mech ion sound like a mousefart.

On a different variety... my 8inch nemesis barrel with an M50 tip is extremely quiet on my Phenom x7.
The flight and landing paint on the target is very clearly heard over the shot itself. I was a bit surprised.

I did the cat test. Instead of her fleeing for her life she merely moved in annoyance.

Carbon barrels sealed right or a shocker nxt with my freak may be some of the quietest I've heard in a hot minute. It's been a while.

It's hard to talk about barrels without talking about paint. But let's just pretend we have the perfect paint match.

Based on the guy behind the Phi barrels, the punk works barrel tests and some anecdotes, the leading recipe for a quiet and efficient barrel is:

- smooth finish
- control bore for 8-9"
- then a 0.005 bore expansion
- however much porting one can put up with for length, longer being quieter

Materials = ?

I think a "quietest" barrel test would be amazing! We've seen test for "accuracy" and "efficiency."

All one would need would be an Sound Pressure Level (SPL) meter, audio recorder, an outdoor space, a bunch of barrels, and a whole lot of paint and maybe a close and open bolt gun for comparison sake? Probably a reference tone and measuring tape to insure all the audio stuff is calibrated properly each time. I dunno. But it'd be fun!

Kinda like this, just quieter:

It would be so sick to see an "+/- dB SPL" rating on a barrel package.

BOA Concealer is the absolute quietest.... I'm running one on my VM and you can only hear the action of the gun not the actual shot

[Rusty Brass]

So it just sounds like a large pile of metal getting dropped on a slightly quieter pile of metal?

[Chaos]

LOL..... if it was a standard VM maybe,my has delrin internals so it's quieter than standard ,so that coupled with the BOA and it's pretty damned quiet

[Jordan]

A Typhoon with porting, on Co2.

Yeah, my old Hurricane with dual spiral porting was stupid quiet on CO2

[Levi]

Regarding the BOA Concealer... does the small paint down a big bore lessen the quieting effect?

I never really chased "quiet" but I remember first with the J&J ceramic and then the All American... both of them being much quieter than stock un-ported barrels. That always seemed good enough. Considering the close range we play at, is there any real tactical advantage to being quieter than those?

[Jonnydread]

Generally no, but I was playing a lot of woodsball when I started this thread and it absolutely makes a difference in the forest. Nice necro btw that's a meaty one

14" og Bob Long LongShots are my pick.
anytime someone shoots any of my markers with a longshot, they always comment on how quiet it is.
Sort of like Chaos said, the sound of the internals working is distinguishable from the noise at the end of the barrel with these.
i have one on my sanchez, if you remember shooting it at Santaball. I think you might have even said "Wow,
thats pretty quiet"
Not super common, but i have a buddy with a pretty big pile of them for reasonable $ if youre interested
ive got a 12" also, but it is not at all as quiet or consistent. and needs higher psi to hit decent fps
also notable,
BMC has never had an issue freak boring them
and the "BL\SS" stands for Bob Long Signature Series, not 'stainless steel' these are aluminum and very light

The craziest barrel setup I have EVER heard is a bit hard for me to piece together (it wasn't mine so, I can't pull it out to look at it). Back in the mid 00s, there was a company making a barrel with a continuous, full length underbore, (like .678 or something), and the exterior of the barrel was smoothly tapered towrds the muzzle end and the breach end was close to 7/8". The barrel had linear porting that started out with very tiny holes towards the breach end and, they gradually got wider until about conventional porting size at the muzzle, with maybe five linear rows. Does anyone remember this barrel? It was a high end boutique kind of production barrel at the time.

That's not the whole setup though. Put that barrel on a Mini and then, slide an old school TASO (holes and scouring pads) silencer over it until the attachment portion of the TASO snugs over the breach end of the barrel (in other words, barrel and porting inside silencer body).

This was the most stupidly quiet setup I have ever heard, with three shots sounding like a very quiet, and low frequency pszoo pszoo pszoo. That was at the muzzle. At a distance of about 20ft and just around the corner of a building, he sound of the gun wasn't that much louder than the sound of the paintballs flying past.

I would've paid good money to have this barrel on my FN303 but, when I tried it, the bolt would get stuck in the barrel, and the bore was a bit too tight for FS rounds for efficiency, and of course, no rifling. It worked perfectly on the Mini with regular paint though.

Lucky Un1tech on a Gen E Matrix. Only sound was that low "thpt" the ball itself makes when displacing air.

[Drunkscriblerian]

In terms of sound reduction, the SP All-American. I remember throwing one on my Pro-Lite and being amazed at how much quieter it was - it turned a loud "POP POP POP" into a much quieter "thud thud thud". Granted it didn't make my Pro-Lite quiet by any means (Tippmanns gonna Tippmann) but it did make it much quieter. It also reduced muzzle discharge, even on a cold morning, which was something I appreciated trying to snipe at people in the woods.

Loudest setup I've ever used is my RT-equipped A5 with an 8 inch LAPCO BigShot. That thing sounds like a tommy gun. Inaccurate and difficult to keep at velocity, but man it looks and sounds mean as hell.

Quietest setup I have ever used or encountered is my Nova N-1 with the stock barrel. That gun is so quiet that even testing it indoors my SO couldn't hear it in the next room, and we have thin walls. By contrast I tested my A5 inside and we were both worried someone would call the cops.
