Even with a Teflon cylinder, PolarStar 90 degree piston and an upgraded cylinder head?

Yes. The only thing that matters is the VOLUME of the cylinder. You will need a bore up kit to be able to fit in a 650mm barrel, and you still won't get extra accuracy, just have spent extra money. Use that suppressor as an actual suppressor, not as a near useless barrel extender.

Grass... I think we need to write up an explanation.

Ok... so the cylinder pushes air into the barrel, and the bb is propelled. Natually, the air starts to escape before the bb does. This is fine, but up to a point. Most say around 500mm. At this cut off, most of the air is out of the barrel, and the bb is unstable, because there is no air "cushioning" it. The bb starts to bounce off the walls in the barrel, leading to less accuracy.

Get it? Tell me what you don't understand...

Installed the PDI Hop-Up and the 650mm 6.03 about 2 hours ago... no problems whatsoever

The grouping is amazing, the gun is whisper quiet, and it is shooting really hard with just the stock spring in. I have been tinkering with the hop-up for the past hour and I think I almost have it

I don't have finals tomorrow so I am staying home and I should be able to get it shooting perfectly.

Yeah, my gun shoots lightning bolts.

Haha, I'm sure you're exaggerating a wee bit. When I've put in a stronger spring, usually the gun is pretty loud. You can really start to hear the piston head slam and the air "crack" out of the barrel. What mods have you did to make it quiet?

Also, usually when you get a longer barrel, it hurts accuracy more than helps. I've explained this before. It's always nice to be proven wrong though... I'd love to see a side by side comparison. You'll need some evidence to say that your groupings are "amazing". Got a target?

And isn't the stock spring like 450 fps? Or was it pre-upgraded, as I thought before? That isn't that hard, silly :

Alright well I am shooting with .30s, so what would it be with the stock spring now? 10-15 less?
If you're talking fps, no, more like 100 fps drop. This doesn't matter as explained countless times.
Whatever that doesn't matter, anyways I really haven't done too many modifications to it. I did stuff it full of memory foam though, and a suppressor that had come with my SCAR from some guy on eBay is custom made and it makes a cool air noise when you shoot it.

I'm sure it's just so quiet because of the stock spring, I am going to put in my M170 tomorrow, I will tell you guys how the noise is then. Also, I will take pictures of the target shooting with all of my springs from like 100ft, 150ft, and 200ft. With the 650mm installed.
Ahh, don't do it! Gonna wreak those sears. Read up on gun mechanics. Unless you have a highly upgraded trigger, your guns won't last.

The stock barrel on my gun is 515mm (weird), so I am going to order a barrel a little longer than that, just to try the grouping thing like you guys said.
Why longer? Get one shorter, and we'll probably see a noticeable sentence.

And grass, hahahahaha! I'm almost caught up to you though... 301 posts!

Hmm... Sounds like you have some major spring degradation. I'm 15, and there is no way I can pull an m190. I'd have to see that to believe it. I'm not what you'd call weak either.

Point One: YES do not order a 510. If you really want to test, get a shorter barrel, like 450-500mm.

Point Two: 45* sears can't hold an m190. The piston will slip off and scar the cylinder. I really, really doubt this claim.

Also, I really doubt that your dad could just "BAM, reinforced the sears" like that. What techniques does he use? He would have to have some gnarly equipment, like a carbidizer, or a heat treater? What are his techniques? Cause right now, this sounds like a heap load of BS.

And yes, the sears could never ever hold an m190. Even if he miraculously made them super strong, because we all know any ol' "airsoft gun tech" can do that, the 45* sear would slip and scar your cylinder, and slam fire. My BS radar is going crazy right now.
