STO Falx

I recently purchased a Taipan Veteran and was a bit surprised by how loud it seemed. Relative to my Daystate and FX rifles it was quieter, but louder than I had expected.

I have two high end moderators(0db and Impulse Air with an additional baffle) on my other air rifles, and I figured I could check them out on the Taipan.

Frankly they produced no significant sound reduction other than a minor tonal change. I used an iPhone db meter (no change in db noted) and I realized it was inaccurate. However to my ear, the two high-end moderators I tried produced no significant audible change.

I then decided to purchase a Silent Thunder Ordinance Falx based on their description of the Nicola Tesla Gas Diode implementation. I contacted the company and they quickly replied with a suggestion for the standard unit for shooting JSB 18s at 850 FPS. Frankly I did not expect much.

However to my surprise, the reduction of sound was extremely impressive to my ear. I tried it outside and in my garage and the difference with and without the moderator was substantial. In fact, it was far better than expected. It truly quieted the Taipan to my expectations.

I have absolutely no tie to STO, and I'm writing this just to help others. The problem I face is that since there is no airgun shop nearby, I have to rely on online reviews which are often inaccurate. I've been disappointed more than once. Online moderator reviews are especially difficult to interpret in the context of your own expectations.

My hope is that this short note will help others decide.

STO makes very impressive airgun silencers. My experience with Impulse Air vs STO parallels yours.

Something else nice about them is the elastomer baffle which would never survive even a single shot from a firearm.

I really wish they would make a Sarissa High Flow m18x1 with a 45 or 50 caliber bore. My new to me Megalodon 457 sounds like a 45 acp.

Try a longer muzzle brake. They knock down the report to the extent that uncomfortable noise is dissipated, and as a bonus they calm down muzzle jump and kick enormously. A big bore isn't going to be mouse fart quiet like the smaller bore's, nor backyard friendly.

I am well pleased with STO products. They are my go moderators, buy a new rifle buy another STO. I am limited in manufactors, Huma, Silent shot and STOs. They are plus or minus a couple decibels of each other. The tonal quality of the STOs make stand out, lower frequency is lower perception of the bark, in my ear. I've 3 Falixs and 1 Sarissa, the Sarissa is quieter than the Falix. For walk about I prefer the Falix, easier to navigate brush while I use the Sarissa for backyard neighbor friendly.

I have been hoping to get one for a long time. They have done extensive research and so far no one has given negative review/information about them.
I contacted STO about their silencers in 2021. They wouldn't ship internationally for a good reason. I then asked their permission to delegate things to Krale.
Krale responded well and I sent them the required contact info. Unfortunately nothing came out of it for whatever reason.I was really hoping to be able to buy STO from Europe. I guess they have their hands full with all the top names all over YouTube 🤣
