barrel tightening?

[jaa]

I know there's a ton of factors that go into an airsoft gun's power and accuracy, but have many people gotten better results out of their guns by tightening the barrels? or are stock barrels good enough?

[LyquidFyre]

Well there's varying opinions on different makes/brands etc of tightbore inner barrels but the general consensus is yes they make a difference.

Search the forums for tightbore reviews.

I use KM TN 6.04mm barrel.

With the 6.04mm and 0.2g, the accuracy was only slightly worse than stock barrel with 0.25g.

So that's a good improvement.

I have a question about these as well...if you were to double the length of your 6.06 barrel by replacing it with a 6.03 barrel (concealing it within a suppressor of course), would you need to upgrade any of the internals as well for any reason?

I've never played around with my guns internals before for fear that it'll meet the same fate as most other things that I've taken apart and put back together, so I have no experience in internal modification.

internal modification was a bitch for me, especially trying to put the mechbox back together without having the trigger, spring, and gearbox pop out of place. That was such a pain in the ass, I wouldn't want to do that again.

Anyways, ya, if you change ur barrel double the length, you will need a new cylinder, which is a part of the internals. So you will have to fiddle around. Otherwise BB sucksion happens and your velocity goes down.

You would need to change the cylinder, there is a thread on the boards explaining cylinder and inner barrel matching.

Edit: Damn people typing faster than I do...

But it feels good once you put it all back together and it works. It's like the feeling you get the first time you built your own PC.

[TokyoSeven]

Build your own PC, enjoy it for 3 seconds till you turn it on and nothing happens. Get frustrated and smash the monitor.

I see. The thing is, my gun is, internally, an out-of-the-box TM G36C (6.06 barrel, 247mm length). All I want to do is replace the barrel with a 6.03 tight bore while adding 205mm, increasing the barrel length to 452mm. So since the barrel won't be exceeding even 500mm, would cylinder modification/replacement really be necessary with a mere 20cm extension?

[Dawnbringer]

I don't have much knowledge on the subject past what I read here. (well also that if you put a ported cylinder in backwards the gun doesn't work). But I imagine that (almost) doubling the length of the inner barrel with out changing the cylinder will cause some performance issues. What would happen is that the bb is meant to clear the barrel by the time the piston starts coming back, as the barrel is longer this wont happen, so that as the piston is coming back is sucks air back down the barrel slowing the bb down.

I think Jaa does not get the concept of a tightbore. It's not something you can do to a barrel yourself.

Let's do some math to explain it.

The bb is 6mm wide.
The barrel is anywhere from 6.02 to 6.05 mm wide.
So you have between 0.02 to 0.05 mm of space between the BB and the barrel as the BB goes downrange.
The less play, the better NORMALLY. But that also depends on the quality of your ammo, the quality of the barrel, and how clean you keep it.

For some folks it makes a huge difference, for others it does not work. Stick with a non-modified gun until you really know this stuff.

As said by many others; play for a good season and read/go see before even thinking about such things. There is information about tightbore barrels you can read already posted.

Is there a place I can go to get an upgrade professionally done? and how much would it cost?

[Mr. G36!]

You can mail to 007 Airsoft and he (Ken) will do it for...a lot probably.

I saw a thread somewhere in this forum stating which type of cylinders you should be using.

The changes you have to make is every 5cm.

But seeing how your gun is stock. I totally recommend you getting a twist barrel instead of anything else.

Yes, you can look in the Doctor's Corner for the List of 'doctors' and pick one.

Or you can follow the basic advice that if it's not broken, dont fix it, and play for a season before changing anything.
