I just bought a 3d printed moderator for my beeman raider and man did that make it quiet. The only thing is it made the POI about 8 or 9 inches lower and that’s at about 15 yards. after Retro I moved to 25 yards and it’s shooting way high. Before With factory moderator it would shout staright from 15 yards out to about 40 yards. This seems crazy to me. Does anyone know what’s going on? Did I maybe buy a cheap or poorly made moderator?

If its shooting way higher than before using the moderator, your barrel might not me tight on properly. Thats what I would check first and all screws.

That a moderator can cause such low shooting at 15 yards and high shooting at 25 yards does not compute. Something is being bumped in between. The barrel or the sights.
Without changing the sights, put the old mod back on and try again.
If the new mod was clipping I would expect large groups. Or if the pellets were bumped down, they would keep going down. A pellet does not know how far away the target is.
9" low at short range should not be possible. If you contact the target with the muzzle, the hole should be low by the sight line above bore. If the mod is deflecting the pellets down that badly at short range they should be lower at longer range.
If you are supporting the airgun differently at short range and longer range the degree of clipping might shift, but that suggest your barrel is very flexible, or the barrel mounting screws are loose.
Place a strip of masking tape over the front cap of the moderator and shoot a pellet through it. See if the pellet hole is near the edge of the moderator bore, or well away from it. If near the edge, you may have some odd intermittent clipping that depends on how tight the mod is screwed on; that sometimes faces down, and sometimes up. Press the tape to emboss the bore hole in the mod. Make sure the action is open and unloaded so you can't shoot you fingers when applying the tape...

After looking at my original post I realized autocorrect got me And I might not have explained it very well also. So with factory moderator the gun was sighted in and on target from up close and out to about 40 yards. I put the new moderator on and at 15 yards it was shooting way low. So I sighted it in again and then it’s back on target At 15 yards. Then I moved the target out to 25 yards and it was shooting high. I don’t understand why after I sighted it in with the new moderator it’s not shooting straight from up close out to 40 yards anymore like it was able to do before. Everything seems to be tight on the gun.

The pellet path is curved. You have to crank in elevation to hit the 40 yard target. Perhaps the new moderator is heavy and pulling the barrel muzzle down. More sight elevation is required to fix that. The elevation change induced at 40 yards is 40/15 x the required correction at 15 yards...

What material was it printed with? How tightened down is it? It sounds like an alignment problem but what a wino (what do I know)?

I think I understand what you’re saying. I didn’t think of it that way before. So it sounds like if I was happy with the trajectory before, I will have to got back to the factory one. I hate that because the new one is so quiet.

Nick, the devil is in the details. You may be able to get a quieter mod that does not do odd things to your system. Can you post a picture of the problem stup?
Does the stock mod look like this?
What does the attachment look like? Male or female thread. Diameter / pitch?

Yes that is what mine is exactly. 1/2x20 female threaded. There are some baling on the inside of that factory one but it’s not much and doesn’t do a whole lot.
