I have an unregulated .177 Revere that is easily the loudest air gun I own. Even with a moderator it is still not hearing safe. Has anyone else ever experienced this? the power level is also lower than it should be, only making 15 ft lbs with a 13.4 pellet. Any ideas ?

Shrouded? a 8 ish grain pellet at the same fps as your 13.4 would use a lot less air (noise)

Yeah mine is stupid quiet with a quality moderator. The shroud really does nothing as the barrel is right at the end of shroud with no real directing of air backwards. I have used Huma 30mm 3 section mod and OldSpook Carbonfiber mod and both do wonders on the revere. Mine is running maxed out on hammer spring shooting 10.3 gr at 900 fps.

Thanks for the responses guys. To be honest, I have not fired it without the magazine in place or done the tissue test. That could account for the low power level as well. Will give the tissue a try this afternoon.

Would the same type of loudness occur using a 70 durometer pellet probe O-ring instead of the specified 90 duromete? (FAC rifle)
I ask because my (new to me) Revere 22 blows some air and noise back out of the breech
Thanks

Ed, I had the opposite problem, got some harder breech o-rings that didn't seal as well as the OEM which were a lesser durometer reading. Some of them just don't quite fit as well.

Update.... So, I removed the magazine and attempted to install the factory single shot adapter for the tissue test. For some reason it would not snap into place, so I break out a small flashlight and have a close look. Low and behold, there is a small loop of O-ring protruding from under the rear of the barrel. That explains why the SS adapter didn`t fit and the extreme noise, along with the low power output. I assume this is going to be the upper O-ring from the brass transfer port. Not going to send this back to AOA for a simple repair, I will take this on myself. Thanks to all for the guidance.

Probably botched the photo thing, but that's new to me. Got to believe this is the issue, never had a problem inserting the magazine, so never noticed it till now.

Well, that's just weird. I'm not sure how the TP O ring would get there, but it's worth pulling the barrel to investigate.

I'm going to go out on a limb and say that can happen if one fires his PCP without closing the bolt.

And none of the 4 screws securing the barrel are loose.
Is that correct?
Ditto for the 6 screws holding top and bottom 1/2 of the block together?
Just asking, not criticizing.

Rifle was never fired by me with the breach open. Barrel set screws on top are snug, have not disassembled the lower block to see if the bottom 2 set screws are tight. The gun is as delivered from AOA. From my initial chronograph testing, it has always been under powered and super loud.

You'll have to separate the action components and remove the barrel to see what's going on. If you aren't comfortable with that, just send it back to AOA.

My plan is to fix it myself; it will be easier than boxing it up and shipping back to AOA. I have 7 other PCPs that I have had to make various repairs or modification too, so pretty comfortable tearing into this one.

I just posted today about a similar issue I’m having in a new revere. (See Sure glad this wasnt an Fx.) I guess daystate appears to have Qc issues too.
