5 Minute Fix: Air Seal Components 

I know this is an older video but: you want your gearbox to produce a larger volume of air than necessary when it is new. Reason being spring tension and seals will deteriorate with time and thus reduce the air volume gradually. If your gun preduce just enough volume to reach the end of the barrel your gun will underperform after some time.

Not sure why you mentioned gear ratio -- has nothing to do with the compression volume. Did you mean DSG/short stroke vs standard SSG, bore-up compression parts, or standard cylinders vs elongated DMR cylinders? For undervolume situation, there is no vacuum happening, its just loss of positive pressure before the BB exits the barrel. The pressure never goes negative in the barrel -- it's practically impossible. For overvolume situation, its not necessarily an issue with putting wear on the system. The concern would be that the airseal components would need to be good enough to handle the higher pressure to not leak air and cause FPS loss/inconsistencies. If airseal is good then you have to worry about joule creeping as you go up in BB weight. Reason why airsoft sites should be chrono-ing with at least .28g BBs. Hey if you guys ever want someone to consult on more complex tech info, hmu on Instagram @midwest.tech. I'm in northern Illinois and I'll be attending UW-M next year. I really enjoy your presence in the industry and would love to help out.

3:14 nice catch lol

Bruh wtf… gear ratio is not ratio between the cylinder teeth, if u have 13:1 or 16:1 the cylinder is moved always the same distance -> same air volume pushed… also you should never have full cylinder if you use any standard barrel length. Having lower air volume than the barrel doesnt have almost any negatives… it have positives acrually as long as you are having drilled port as the piston reaches higher speed as no air being compressed from the beginnig thus compressing much faster increasing muzzle velocity while having lower air volume zulul… your theory is missing the part about speed of the nozzle while compressing or not compressing… also i tested this from 500 mm to 200mm barrel full to half cylinder and best results are with about 2/3 cylinder volume and basically any barrel lenght gives the best… accuracy is almost the same

Wow so since I put 16:1 gears in my CYMA AK with a 509mm barrel am I now under volumed? I didn't realize that higher gear ratios = less air volume

You mean number of teeth right? Ratio doesnt concern the compression

This guy thinks a higher ratio set of gears will pull your piston back so far back that it will be in the buffer tube. 😂

Man, I am out of breath just listening to him. Gotta take a break and breathe!

So far I've upgraded my lt-12b evo Gen 2 with an all metal V2 gearbox to a flat hop bucking and nub and added the m120 rated upgraded spring. Should I go ahead and do a full hop up unit upgrade or can I get away with but piston upgrades first

Good info!

I want that shirt

What is the cylinder volume to inner barrel volume ratio? I've seen discussion of that under BASR forums, but I'm not sure what it should be for AEGs or GBBPs.

Como podemos mejorar la compresión del cilindro sin afectar los fps?

Best gear ratio to achieve 600+ fps?

This guy looks similar to chris evans😃

I just had to do all this to my lancer lol
