I can't see the Odysee video. Same thing happened to me yesterday until I converted it with free software called HandBrake. I am looking forward to timing it.
I just got back from the range with the fam and the FFT TX22 was a big hit. Wife and Son loved it. My son was able to squeeze 5 burst from the 16 round mags but not before he did about 10 mag dumps.

I relate the experience to watching Die Hard at the theater the first time opening week.
Wife was so excited. She actually giggled. She broke the McFadden lightning loader TX22 adapter loading mags. I'm going to make her buy me gun stuff parts.
I used CCI SV 40gr RN (which is subsonic), CCI Subsonic Clean 40gr RN, CCI Sub-sonic 40 GR RN and CCI MM 40gr RN
I tested them with the Spectre and the Sparrow. None of the ammo worked with the suppressor attached.
I will be testing with Root's weights soon. Fun times.
