I don’t want to be a hater, but you’re wrong about a lot of things in this post. Supressors do not slow a projectile, and in most cases actually increase muzzle velocity due to increased dwell time for gas expansion. They suppress muzzle flash and report by containing said gasses. Sonic booms still happen, and supressors work more effectively with specific sub sonic ammunition, which is usually achieved with a heavier projectile weight lowering the velocity.

I’m not trying to dunk on you here, just trying to educate.

Obtaining a supressor isn’t too difficult, but you do have to be thoroughly screened by the ATF after submitting photos, fingerprints, and a form, and a $200 tax, which leads me to believe this suppressor was homemade and lacked a Nielsen device, see my thread above.
