It was sparky for the first 25 or so rounds, as all titanium cans are. There was not much blowback. I'm impressed by everything except the direct thread only mount, which I have a plan for.

I sent it off to Ecco. There are several issues, the S/N placement and very short blast chamber. I'm confident Nick can make it do what I want. I the mean time I picked up the F4-L and will hopefully be able to test it next week sometime.
