Umarex Notos Versions
- Thread starter K80
- Start date
Firewalker recently stated that:
Notos generation l guns had two tapped holes on top of the receiver, tighter barrels, were accurate but the bores lacked polish and often needed hand lapping to tighten them up.
The Gen ll guns lost the second drilled/tapped hole on top of the receiver but the barrels were a little better made and didn't foul as quickly.
The Gen lll have very deep, tapered crowns, some 1/2" (12mm) or more. These barrels are even looser but pretty smooth.
So it sounds like it would be difficult to determine a generation 2, from generation 3, without pushing pellets through and comparing, or removing the built-on moderator, and examining the crown of the barrel.
Perhaps he will chime in, with more information.
Serial number identification would be great, but Im not sure that even Umarex would provide that information.

I have such a small sampling that serial numbers are irrelevant and because they use the numbers to relay internal information, without a key from the factory, I'm at a loss.
Generational changes have been both subtle and bold but this is merely a guess on my part due to changes in construction features.
Barrels are serialized as well but they appear to be linear as the numbers seem to be increasing. I have not recorded them as a matter of course as I modify them, nullifying warranty.
