If you are using on a gas gun at all the .46 cal brake has MUCH less blow back. I had a 30 cal and sold it because of that. They almost sound the same but still really helps recoil.
I’ll mainly be using this on bolt guns, but that’s good to know for sure...I’m swapping everything over to keymo mounts to make swapping rifles/cans easier, so it’s very possible the hybrid could end up on a gasser occasionally.
I never think about eBay for gun stuff now, so used to them being anti gun (AR’s in particular it seems), I forget to even look there for other components.
