theres any way to make the Flatline more silent?

im gonnaa have to agree with hybrid sniper. who cares any way just become a better player

Hmmmmm the last time I looked...its called Freedom of Speech, you dont like it, then move to Iraq!

And watch yer language, thats the quickest way of gettin the boot from the forum....thats if you wanna stay and belly ache.

It is pointless to make it silence, and not to mention illegal.

You heard right, but it doesnt do anything....the Flatline barrel isnt ported.

this entire topic isnt allowed in the tippmann forum if a mod sees it theyll shut it down

Yes, shoot from farther away. 

The flatline is all about putting accurate long range fire to your opponent.  I've always used the noise as intimidation in pinning down opponents on the field.  If you're really worried about making too much noise when everyone is running around with their hearts pumping and the adrenelin is flowing.  I suggest you invest in a slingshot.

You tell him.

You are getting way to much into woodsball sniper crap if you want a silencer. Don't even bother.

Focus on shooting people.

if your 80 feet or a little more away @300fps, your enemy will be hit before he hears it. so work on that.

try drilling some porting holes in the bottom of the barrel and let us know how it works...

OK   ty for ur opinions...

Yes, listen to Halo and pballa jr.. Don't drill any holes in your barrel. Don't drill holes in any barrel.

The pvc works well as a shroud. The more porting in the barrel, the quieter it is. Usually the most difficult part is getting your shroud attached to the barrel, and not make it permanent.

Jesus, I explain this every time and no one ever gets it. READ THIS.

Why does your gun make noise? Well, it's not from an explosion like an actual firearm. So what is it? It's 800 psi of air entering 14 psi of air through a .68 inch hole. It makes a "pop" sound, much like a pop gun, although it is a higher psi so the "pop" sounds more like "boom." To correct this "boom," technology has brought us these things- porting, fluted porting, and lower psi without affecting velocity (increased volume).

What can you do with a flatline?

Well, you can get a muzzle break (or make one) with fluted porting and a break at the end. Look for about 4" long.

Drop your operating pressure. Get the comp-air system, polish your internals real good, a get a maddman spring kit and use the stronger drive spring. Make sure your velocity screw is flush with the powertube so it doesn't obstruct any air. Then, use a low pressure reg to drop the pressure as low as possible. Careful, on the A-5 too low will cause Cyclone problems. The 98C is more open-ended.

Man, all that jus to make the Flatline a lil quiter....heh jus leave the damn barrel as it is, theres no point in messin wit it and who really cares how loud the Flatline is!!!!!

man this guys an expert.lordjovian i mean.

Not an expert- yet. I haven't got the calculations on the predicted output velocity of the A-5 yet. Nor have I gotten around to finishing my no-chop bolt (A-5 & 98C). Having some minor spring problems.

evil, if thats what he wants, thats the work he must do. Where theres a will, theres a way.

I see evil's a fan of Modern American Tradition- less work, more play.

Things we have done. 

Flatline. Muzzle break as LJ says, or a barrel extension, just like a regular firearm, with porting. Works pretty good. No point though as it extends the barrel to much and keeps you from playing well. Ther eis still muzzle noise, but you mostly hear the marker action itself.

Regular barrels. JJ ceramic. Limited, smaller porting. Built a shroud to cover the barrel from one end to the other, packed and ported. Quiets the muzzel noise tremendously, but once again, you hear the marker more at this point.

32 Degrees Whisper. Lots of porting, large holes. Built a shroud same as above, it was a little softer in the muzzle noise than the Ceramic, but not much. Once again, you hear the marker.

If you stand 20' out in front of the muzzle and listen to the report, you will tell the difference. If you are the one firing the marker, your ear is in the same spot as the action, so you cannot hear that much of a difference. Think about when you are standing by a creekbed. You can't hear some one yelling at you, but they can hear you just fine.

Comp air does quiet your action down quite a bit as well. Gives you consistency, and no trouble in cold weather. Just figure out what kind of playing you want to do and stay with it. If you got the flatline, maybe stick with that, or if you don't mind the extra length, mess around with a barrel extension. You have the roon. An A-5 flatline is pretty short.

Our little A-5 group has all the A-5 upgrade combos you can get and we have swapped parts and tried all sorts of combinations from R/t, E-grip, Flatlines, a wide variety of barrel swaps, comp air, expansion chambers, regulators. This sport is way too addicting.

You can whoop the best out there not with what kind of marker you have, or the setup, but how you play as a team and how stealthy you are as an individual.

A-5, flatline, comp air, e-grip, 32 degrees terminator

You have it turned around....its work hard and play later...money talks and the BS walks.

dude i aint new ,but there gonna hear you unless their deaf flatlines wont work with a silencer.  However if you want to have a more silent gun and are willing to give up the distance and the extreme accuracy. get a whisper made by 32 degrees.

ps. if its windy even with a flatline you wont be very accurate.

It seems to me most of you are dodging the problem here-

Many of you are saying, "It requires lots of work to quiet the Flatline, so get a xxxxxx barrel instead."

So, if I want my A-5 to have an anti chop bolt, screw it and get a different gun?

Or if I want my A-5 to shoot faster than 15 bps on full auto, screw it and get a different gun?

Also, if I want an adjustable trigger screw the A-5 and get a new one with one?

You guys are overlooking the reasons there are mods. That's part of what makes Tippmanns so great. You can perform a mod, make up your own mod, and just tinker the crap out of it until you get the performance you want. Sure, it's easier to go drop some bucks on another gun (if available), but the key here is to spend a significantly smaller amount of cash on a mod to challenge expensive parts for other guns. Plus, the "surprise" factor comes into play when players who think Tippmanns are slow, heavy tanks get to see a Tippmann shoot as fast as their Matrix. It also works even better on the field when someone thinks Tippmanns have no accuracy, don't bother to even flinch when you point your gun at them, then they are stunned after seven balls splatter on their face mask incredibly quick.

Anyway, he wants to know what can be done to silence the Flatline. Not what other barrel, not even how it works (thats extra info), but WHAT he can do for the FLATLINE.

He likes the Flatline, he wants to keep the Flatline, and he just asked if there's anything he can do to get the desired performance out of it.

And polishing the internals and changing springs is hardly work, poking around the net for a muzzle break with some mouse clicking is hardly work, the only difficult part is chrono'ing and adjusting the reg for a period of time.

I'll try to stick closer to the point with this post.  Firing a marker (or an actual weapon) creates two distinct separate sounds:  The pop from expanding gasses exiting the barrel and the mechanical sounds from internal operation.  As someone pointed out above, for firearms that fire above sonic speeds, there is another sound generated when the projectile exceeds the sound barrier, but that does not really apply here.  (I refuse to play with anyone whose paintballs exceed the speed of sound.) 

For paintball markers the easiest way to quiet the "muzzle blast" is to change barrels, as that is not an option in this case, we have to look at what else can be done.  Obvious solution; since the sound is caused by the rapid expansion of excess gas as the ball exits the barrel, reduce the amount of gas used to launch the ball so there is less pressure behind it at the muzzle.  This is the theory behind porting.  It allows the force behind the paint to bleed off slowly as opposed to expanding rapidly as the ball exits the barrel.  I would not recommend that anyone port their $100+ flatline barrel, but if I was going to do it I would start the porting just behind the muzzle break and only port the bottom of the barrel.  Theoretically, the ball should never come into contact with this portion of the barrel so it shouldn't screw anything up to bad.  (Of course removing any burrs from around the porting without damaging the friction creating surface within the barrel would be a serious challenge.)  Another possible approach would be to port the bottom of the barrel just within the front end of the shroud, then port the shroud itself and fill it with a sound deading material.  IMPORTANT DISCLAIMER:  THIS IS JUST THEORY, I WOULD NOT RECOMMEND DOING THIS, NOR WOULD I DO ANY OF THIS TO MY FLATLINE.  Now for what I would try to reduce excess pressure at the muzzle.  Besides what Lord Jovian mentioned in his posts I would play with the stock velocity adjuster (with the stock spring and end cap in place) until I determined at what point I got maximum velocity from the marker.  Then I would swap parts out and play with different combinations of springs and RVA settings to see what combination got me the most acceptable combination of velocity/accuracy/noise.  As I mentioned earlier, you may suddenly find an increase in paint breakage.  Additionally, you may not find a velocity and noise compromise that is satisfactory.  That would be the point where if you were still interested it would be time to check out installing the parts to operate at lower pressures.

For the mechanical noises I recommend getting a rocket cock.  Closing the charging handle opening does help stifle the noises emanating from it during use.  I recommend the plastic ones, IMO the metal ones transmit noise better.  You could also experiment with slightly thicker buffer O-rings or ones made of a different material.  The internal polishing Lord Jovian mentioned above would help; especially around the rear bolt.  Do not pad the front of the rear bolt or the rear of the valve.  I have seen this recommended elsewhere to quiet the mechanical action of markers.  Such padding were it of sufficient thickness to actually work would also interfere with the bolt striking the valve plunger and interfere with the operation of the valve.

ok i want to know why every one is trying to quiet there gun??? Im trying to make mine louder because ok here look: what are you gona be more afraid of?-an guy shooting a scilenced paint ball gun like 7-8 balls a min trying to keep quiet

or

-a guy with an A-5 on full auto shooting at you with a giant boom for each shot?

really...

This thread needs to die!

Why would you want to make your gun quieter?

Here-

When my gun sounded like a canon, as soon as I'd start shooting everyone on the other team would duck and take cover quickly. I can't shoot them if they're behind a bunker (except once).

When I fixed the canon noise, now I can catch players unaware. While one is shooting at someone not in my direction, he can't hear my marker over his. By the time he realizes I'm shooting at him, there's 10 paintballs flying toward his chest.

Thats why expensive guns use lower pressure, and thats why players using them usually seem more skilled- you don't hear them shooting at you, so you don't take cover until you're already tagged out.
