Pointlessly trying to suppress a Baikal MP61 airgun.

[@shovelchop81bikeralex52]

Stuck a stupidly long moderator on mine, something like 18" long, can't remember if it's any quieter but at least it fits in my gun racks now!

"Functional" is "functional", even if not "for intended purpose" I guess!

[@mildyproductive9726]

Ha, nice. Funny intro. The barrel on this gun is ~18" long and it's only 3 ft lbs. After the first ~5-6" of barrel, the pellet is max speed. Then there's ~12" of barrel leftover to act as a decompression chamber for the small amount of compressed air. On higher powered break barrels, there is significant muzzle blast noise. At least for everyone other than the person shooting it. And this can be reduced with a silencer.

[@MyAirgunPhase]

Thanks! And yeah, I know a lot of the things I do are silly, but I'm curious, and I like to document things for others who might have the same silly ideas. With low-power springers (i.e., just about all the ones where I am), most of the noise is literally inside your head from the sound of the action. However, some are a lot quieter on that front, like the HW30. So yeah, nothing too scientific, just in case anyone else was wondering.

[@mildyproductive9726]

Right on! If you want to hear silly, I have a similar power springer. It shot groups like a basketball at 10 yards. So I cut the barrel down a couple inches at a time. The groups got tighter each time. It finally shot accurately with my lightest pellet when the barrel got to 7". When I cut it to 6", it now shoots accurately with every 7ish grain pellet I tried. Adding a length of pipe over the barrel to help cock it, I discovered just how much louder it had gotten. I could tell the difference when shooting it. When I had a friend shoot it, and the difference in noise was pretty impressive! Also silly? The rifle is for kids. And I'm pretty much the opposite size of a kid. I had to make a scope stop that is several inches long, and the front of the scope barely clears the breech popping up when you cock it.

@@mildyproductive9726 Haha, whaaat? I wonder what the cause of the melon groups was? Because it was a low-powered rifle and... didn't have enough oompf to push it out the long barrel, so it got all fussy? Or just defects towards the end of the barrel? Either way, that's fantastic, thanks for sharing! I JUST bought a Hatsan Alpha Striker, a kids break-barrel for really cheap. My intention was to basically maul it and use it in an experiment immediately, but I thought I'd give it a few shots first. It's so so accurate, pellet through pellet at 10m... like damn, why you gotta make it so hard for me to destroy you?

[@mildyproductive9726]

​@@MyAirgunPhase Melon groups? I believe they were from poor tuning from the factory. Well, I mean on cheap guns, there is no tuning from the factory. The barrel locked up tight, the stock screws were tight. The barrel didn't have any obvious defects. So my guess is it was just bad vibrations when the gun was fired. Especially since it had a noodle barrel encased in plastic. But rather than tune these out by altering the spring, I decided it was easier to just shorten the barrel and see what happens. I wasn't that attached, yet. Since the pellet reaches full speed at only 5-6", shortening the barrel means you might get the pellet out the muzzle earlier. Maybe before the worst of the vibrations have developed. Especially on a low powered rifle where the pellet is only doing 500 fps through that last extra 10", it's in there for a significant amount of time. Also, shortening the barrel stiffens it, making vibrations faster but smaller. And it also changes the resonant frequency, so the the worst kind of vibrations might not happen, at all, anymore. Kinda like tuning the rifle via the barrel instead of the spring. That's what I decided, anyway, when I did it. I had read some info about it on GTA forum. There are some people who do this even on $700 rifles to gain even slight bits of accuracy! Down to 9-12" seems to be what the braintrust finds to be the minimum you can go for full powered springers. Data on lowered power rifles like 500 fps is more like 6". My example was dramatic, probably because it just happened to be perfectly out of tune to begin with, creating some nasty vibrations in the noodle barrel. If it starts out super bad, any change can only make this better, right? Whatever you do with your new rifle, I hope it's still as accurate when you're done! And that you post a vid!

[@ayycsii567]

Have you tried tried any Weihrauch products? They say HW40 PCA or the HW30 are really quiet, they have an awesome trigger and are really accurate.

[@MyAirgunPhase]

Yup, got both! The HW40 isn't super quiet, but the HW30 isn't bad. The HW40 has an insanely good trigger though! The quietest pistol I have is the Zoraki HP-01 (/"Webley Alecto") with a moderator on (another one with an amazing trigger) As for rifles, well, the Daisy 880 with the moderator I designed is super quiet (even at 8 pumps), but the Hatsan Hydra is pretty damn quiet too! Maybe I'll go through my list and rank and video them. Anyway, thanks for the suggestions, I really appreciate quiet gun information!

[@ayycsii567]

@@MyAirgunPhase I would love to see your airguns ranked by sound.

[@JV-ly2cq]

I swap the spring for a gas ram from ebay. Took off the front sight and mine showed a thread that actually fits ( pretty poorly ) a 1/2 unf silencer. The whole thing is damn quit. Went from 3 to 4 and some change fpe and is an absolute tack driver with h&n field target trophies 8.64 gr. Really recommend the gas ram from ebay. It really changed the gun.

[@MyAirgunPhase]

Nice going! I've been wondering about the gas ram replacement for it, good to hear it's working out for you. Guess I'll make that eBay purchase then, thanks for the info!

[@JV-ly2cq]

@@MyAirgunPhase just make sure to get the 4.5 fpe one and not the 6 ft/pd. If your government of freedom lets you 🤌. It is sais to throw off accuracy and kill scopes.

[@gugugalnoot]

I own 2 of them, so much fun but not really powerful. OK for 10 meters, maybe 15. Quite accurate to if you get used to it

[@MyAirgunPhase]

Yeah, they take a bit of getting used to, but when you get their "feel", then you finally find accuracy. I kinda like the low-powered-ness of it all, as a lefty it's one of the few side-levers that is easy to cock. And for 10m shooting, works just peachy for me.
