Umarex Notos bravo3d grande slip on moderator

1000027813.jpg
I installed this moderator this morning and went from 1/2" groups to 2" groups. POI moved 2 inches down and left. Is this normal? Is there anything I can do to make it better. I'm not sure it even sounds quieter.
 
My buddy Anton installed a big can on his gun and it also began producing 2" groups.

But in fairness, his was a shotgun and distances were quite close.

In all seriousness, a slight POI shift is to be expected, but if groups open up considerably, that's symptomatic of clipping the baffles. Sometimes you can manipulate things to improve alignment, or you can consider brute force and drill out the baffles for more clearance.
 
Notos is really quiet with oem moderator,dont see why everyone wants to put giant mods on them. Makes a small light gun look all out of proportion.
Agreed

Maybe take off the odd and inspect the inside for strikes, @nervoustrig is right, as long as your groups dont open up you should be fine. I suspect that mod is 2-3x heavier than the factory one.

scarry guy, no country for old men.
 
I have the same Moderator on my NOTOS and It did make it much quieter then factory. Definitely noticeable difference about 8db. I still have 1/2 inch groupings. I agree this sounds like clipping and i'm sure you tried to a align the moderator better. Maybe, Trying a different slip-on moderator (like the CANCAN) if the build-in is too loud for your neighbors (like mine).

Looked clean inside no strikes. I'm going to try and clock it in different positions and see if that makes a difference. If not it goes on the shelf and lesson learned. It does seem as if the notos bark has lessend the more pellets I run through it. It is definitely not as loud as it was when new.

Make sure its seated right, there's is a slot for the original moderator to enter the slip on, I had no issues with mine. Didn't noticed any pellet deviation but I did noticed a noise drop around 8 to 10 db

I have one of Subscriber's designs that replaces the factory baffles and extends out the front a couple inches. It's the same diameter and looks like it came from factory on the gun. I really can't imagine anything being any quieter. I hear hammer drop and pellet hitting target.
I'm not in a location where loud guns are a problem at all and I would run the gun as it came factory before I'd put anything oversized on it. I do not like soup can looking moderators, at all.
But to each his own.. I'm not judging. ;)

I liked the idea of slip on and bot having to take apart, I agree it looks a bit cartoonish.
