G3 Airseal Nozzle

[venture]

Question for the community:

Is a G3/MC51 airseal nozzle compatible with the more common M4 / M16 airseal nozzle? I have a G3 that I am working on, but am out of G3 nozzles.

Also, I am thinking of making a list of nozzles and lengths in mm. There seems to be no table of this anywhere online. You can find lists of inner barrel lengths and the respective models many places online, but not detailed airseal nozzle info.

Of course, there is much variation by different manufacturers. Both from tolerances and from Model variations (Classic Army and G&G M14's use a different nozzle completely than TM, CYMA, G&P). That is where the community can help. If you have a micrometer, or any accurate way to measure length, please measure and report any nozzles that you can identify the make and model of.

For instance:

5KU M14 (TM Type) 23.55mm
5KU SCAR 29.05mm

I am going to measure any I can identify and compile what others post into a comprehensive list that we gun doctors can use to identify suitable nozzles for various aegs.

I would like to mention that it's not all just down to length. The shapes of these nozzles matter hugely. The end bevel shape can affect bucking seal. The outer shape of some nozzles will sometimes change over the length of the nozzle so that it fits into the hopup unit of the type of AEG. Some nozzles have guider ridges on them (eg: G36). I've even seen a nozzle that has a dimple (yes, a dimple) on it. The inner diameter of the nozzle is also key and varies. There are also the various nozzle exit hole designs, not all of which are circular, though I'm not sure how much that matters in terms of one shape vs. another except in how much extra pressure the reduced exit diameter creates.

Basically there are some very big variations in overall design and the ideal thing would be to have some kind of 3d design database

I am just sticking to length right now. I am not even a cartoon, I live in a one dimensional world, length. LOL

I am aware of all of those other features, as well. But if you have a nozzle without packaging, having a length chart is the easiest way to identify it. Those other factors are usually very subtle and can be swapped out with other designs without ill effect. Length, on the other hand, is the single most important feature of an airseal nozzle.

My length list will also sort tiny variations in different manufacturers' products and hopefully will be able to be used to choose the "perfect" nozzle length for the tinkerers and fine tuners.

I mainly mention some of the other factors because I have a very nice Modify M4 nozzle which is exactly the same length as an AK nozzle I have and yet it can hardly move when inserted into the AK's hopup (which is too bad... )

An m4 nozzle should be about 2mm longer than an AK nozzle.

And of course you'd know that because of your 1D database. Well played , well played

I need to obtain some digital callipers...
