Hi my first post here, I have bought the Norica Viriatus a month ago, and I have a problem with it, after measuring the pellet speed with chronograph I found that the pellet speed is very low when the tank is full (250 bar) and after several shots the speed gets higher when the tank gets around 200 bar and keep dropping with shots until the tank gets empty so the curve of shot string looks like a pyramid, It is clearly related to the regulator is not working properly, some maintenance guys here saying that the regulator is not breathing and the air tank must be drilled at the regulator place, I just wondering any one have any information about this or faced something similar? Your help will be truly highly appreciated!

I have saved money for several months to be able to by the Rifle as I love shooting so much and I am really disappointed with my rifle and I hope to get it fixed!

I have contacted Norica but didn’t get any response, also in my area repair shops are very rare and all I asked for help didn’t know what to do!

Thank you 🙏🏻!

Don't drill your air tank...the regulator does need to breathe to atmosphere but it should be fine from factory, otherwise send it back.

The more likely scenario (the above could be possible just very unlikely and if so at fault of the manufacturer), is that the regulator is in bypass mode, resulting in full HPA pressure being present at the valve at all times.

You bought a pcp with very little support. It's a beautiful gun and a shame it's not working as it should.

I'd send it back to the place of purchase if you're not capable of tearing down and diagnosing the issue yourself.

That would mean inspecting the regulator, potentially measuring, ordering and replacing the o-rings, or adjusting it if its just out of adjustment, as well as verifying the regulator has access to atmospheric air, which would require a factory placed hole in the air tube located where the regulators breathe hole is. Could be as simple as that passage way being clogged/blocked by some machining contaminate or the like.

Thank you so much Matt for your reply!

Unfortunately returning it is not possible! So I will try to diagnose it myself and will do the steps you mentioned hopefully to find where the issue is!
