    Moderator Comparison Spread Sheet

    Yeah, it would be nice if it was simple. Still, there should be some value in comparing moderator efficiency on specific guns with specific tunes. Unless the difference is only a couple three dB between them all. But I suspect it would be a decent way to sort out the crappy ones from the...

    Robotic Pest Control

    It depends on how they "taught" it to recognize the mummys. The algorithms for recognition are fairly advanced. It could be as easy as feeding a lot of different images from a lot of different angles of the thing you want to be the target.

    New here but trying to sell air gun

    I successfully sold an airgun and purchased an airgun accessory here after roughly a dozen posts so don't let anyone tell you it's not possible. Some people believe seniority matters and will always try to drive away the new guys. There are other places where people primarily buy/sell/trade...

    Why do you remove the price?

    I like this idea. If not an archive section then at least mark it something like "EXP" for expired so it doesn't show up in current for sale searches.

    Moderator Comparison Spread Sheet

    That would be cool, you'll need a genuine sound meter to capture the actual difference in performance, Smartphone mics need not apply. Think something like a calibrated Bruel & Kjaer meter. But it will get complicated quickly because, as @WI_Hedgehog points out, simply pushing less or more air...

    Sight screw plugs after removing the iron sights.

    Are they headless, cheese head, flat? M5x0.8 is definitely more common. A quick search finds these. I'd have to crack open a higher octane google-fu to find more. https://belmetric.com/m5x0-5-fine-allen-set-screw-stud-45h-din-913-flat-point/

    Why do you remove the price?

    Guilty, I did that here. But I corrected it once someone reminded me by asking if it was available. I see prices remove from sold goods at a lot of sites (not here). I agree it's annoying and it would be better just to remove the whole listing.

    Sight screw plugs after removing the iron sights.

    A thread checker might be useful. Then you might be able to get what you need out of a parts bin at an orange box store or an Ace. I've bought set screws, like 4-40x3/16, for other weapons at local hardware stores once identified...

    What\'s it worth?

    This guy sold one back in January. He was asking $3k but he included a lot more in the package than just a gun and he knew exactly how many pellets had been fired through it. No idea how much he actually sold it for, could have been the $3k he was asking but could have been less as well...

    This is What a Scam Attempt Looks Like

    Well that's disappointing. We'll have to find another witch to burn now.

    That's a nice deal, good catch.

    I use qwerty backwards that way it's harder to guess.

    Why I’m a fanatic about index marks

    The only problem with rubber or soft materials between the mating surfaces is they may not provide a consistent "cocentricity" especially as they wear over time. In the world of normal moderators even wave washers are not ideal. They're great for keeping thread protectors tight but not...

    Why I’m a fanatic about index marks

    This isn't uncommon with normal moderators and I have seen it surmised that air (flash) passing the projectile inside the moderator compresses/bounces off minuscule differences in baffle apertures and "shapes" the flight of the projectile. No proof, only theory. As oldcrow suggests, harmonics...
