Umarex Purchased a Zelos looking for mods

[Mjhiggs16]

I have seen the other posts but a bit confused. I would love to find the cheapest most effective mod to quit it down if that’s baffles or any type of moderator and you have a product please post it here. Also mags. I would like to upgrade to a bottle but I’m not going to bother if I can’t find a 4500 regulator/adapter. If I am missing something please let me know. I have been shooting at about 2500 at 905 with 25.39gr and get about exactly a mag worth out and it’s time too fill. It’s worth it for how accurate it is. First PCP gun and Love it! 75yrd on the target smashing the red

The fill adapter on the gun where bottle mounts is m18x1.5. The raw aluminum piece between gun and adapter is m16x1.5.

interesting on my m60b, that piece is no-rust steel.

I didn't stick a magnet on it, but I figured it was aluminum.

wouldn't help since it's non-magnetic, but seems much harder and heavier than aluminum.

Possibly stainless then.

The raw stub comming out of the receiver is M16x1.5.

Are you saying that you need to remove the stub piece and then you get to an M18x1.5 female thread?

No, the raw silver piece has the m16x1.5 male threads. The adapter with the foster and gauge has an m18x1.5 male stubborn for the bottle to mount on.

So that's male m16x1.5 to adapter, m18x1.5 male to bottle.

So we need a M16x1.5 female to M18x1.5 male adapter.

Which is exactly what's on the gun already. To change that section over to a regulator, you'd need a regulator with the m16x1.5 female on the output side, and an m18x1.5 male on the input/bottle side.

I can't find one when I search online.

If we connect the air bottle to the gun and no regulator then there is no fill nipple.

Exactly. So the option as it sits, is to get the adapter or the altaros regulator. The altaros is m18x1.5 female and male, so no need for an adapter between. Then you add a bottle, and it's going to get a little long. Maybe the zelos won't look too bad because it's already 4 inches longer than the m60b, but I personally think it'll look goofy with all those parts between bottle and receiver.

The altaros already has a gauge and fill nipple also. If a short M16x1.5 to m18x1.5 adapter exists, that would be the way to go IMO.

Well here is one, but I don't know the pressure rating.

Doesn't appear to have any o-ring grooves either. The bottle has the groove in the neck, so that side would seal. Dunno about the m16x1.5 side.
