Can't argue with that as I have no way of measuring. I was speaking of my other M4 though from Mach1. I was only getting 324 out of it, put in a 6.03 and it boosted it nicely. :)

I thought the CAS guns didn't have a tightbore. Oh well... What do you currently have for a battery and where is it stored (stock, handguard)?

Mach 1 and 007 G&G lines are the higher end and are supposed to come wiht a 6.04. CAS aren't supposed to, but Tom seems to say otherwise. I can't say for sure...

Sorry Crunch, didn't see the CAS part. I have the 007 version, G&G Armament not CAS version. And I have a nunchuck battery in the handguard. I bought it from ebaybanned, it said on the website that it was a 9.6v 1500 mah battery, but to be honest it doesn't say how many volts it is on the battery. Is it possible they sent me a weaker battery? The brand is Firerox.

Oh, ok. I thought you had the CAS version. Actually, now I remember talking to you about the barrel some time ago. I'd say there's no need to swap barrels then.

A better battery would do the trick, but you're pretty limited to what you can fit inside a handguard. Always get the highest mAh rating battery you can get. The higher capacity, the lower the internal resistance and the more initial current it can give you to crank the motor over.

So there will be no noticable difference between a 6.04 and a 6.03? What about if i add a PEQ? CAn I get a larger battery then? Or what about a LIPO?

You won't see any appreciable difference between 6.03 and 6.04. Waste of $50 IMO. And yes, a Lipo would work out well. That would fit the handguard easily.

Would the stock G&G gears support a LIPO? They arew steel. What else would I have to upgrade to use a LIPO?

Don't get a crazy-ass high powered lipo and you're ok... 11.1V, 1500 mAh, 20C should do you fine. As long as you don't abuse it with long sprays, you should be fine. If anything is to break internally from the lipo, chances are it will be the piston that strips. And even though would surprise me, at least in the short term.

There are relatively low rated lipo. Using a 7.4v with a discharge rate of 20C or less should not require any upgrading.

Really? Because seriously when I swapped out my 6.04 on my CQB-S version for a 6.03 I jumped up to the 363 mark. I had previously chronod that gun with its stock .04 barrel on two seperate chronos that both gave me around 325ish or so. So in my case, going to a 6.03 made a difference. I have since then further brought both my barrels down to 6.02.

Not trying to argue, would be interested in hearing your take on why I would see that jump though other than changing the barrel out. Both times chronod batteries were fully charged too. So aside from the barrel, conditions were pretty much the same minus a temperature variation I suppose.

Um I will be honest and admit to not knowing about discharge rates. Any sites you would recommend so that i may educate myself? And what kind of MAh ratings do LIPO's have? And also isn't a low mah rating why I have trigger lag? Won't even a LIPO with a 1500 mah rating (the same as my current battery) have the same lag?

Increasing diameter by .01 mm shouldn't give any appreciable increase in velocity. Even moving from a 6.08 stock barrel to a 6.04 shouldn't add any more than 20-ish fps to your velocity at most. Even going from a 6.08 to a 6.01 shouldn't add anywhere nead 40 fps.

I suspect you probably had an airseal issue with your hopup sleeve and that got adjusted when you installed the new barrel.

My tightbore barrel in my C7A2 (Deepfire 6.04mm) got me an increase of about 20 fps. Installing a Systema 6.03mm on my JG 416 got me about a 25 fps increase (both over the stock 6.08). A 6.04 barrel increased my MP5 by about 15 fps...

Never thought of that. Good point.

There are two kinds of pre shimmed modify gears. There is the modular which has a two sided brace and cant be used with reinforced gearboxes and the modify smooth gears which have a smaller one sided brace that doesnt get in the way. The modify smooth gearset is made or use with any gearbox of that sized bushing.

as you can see, the smooths are a bit more money, but they will fir in more mechboxes, and can be taken apart to replace one gear if it should break. They come in high speed and high torque.

If you want to get rid of trigger lag completely, try a higher voltage LiPo with a Trigger Master. It'll keep your ROF down (so reduce the stress on the mechbox) but will take away most, if not all, of the "ramping up" you were mentioning. Just my 2 cents. :)
