Among the hours spent at the range today on half a dozen different projects, I shot the Orca with a PWS FSC30 attached. It doesn’t look like a huge difference on video, but the muzzle stayed on target instead of dipping, and I didn’t notice as much of a shove, recoil-wise, as I did with the A2.
I noticed with both the SCAR-17S (which uses the same device) and the Orca with the FSC30 that I wanted more than just earplugs. I’ve fired a wide variety of weapons, including some that are much larger than 7.62x51mm, and have never wanted double hearing protection as much as I did when I fired these two cannons.
Here is a comparison with the SCAR-17S (both weapons equipped with FSC30).
