I have a Mask. They are worth it. I also have a Spectre ii. I was concerned about FRP when I bought it, not so much now.
I just did some research and Silencerco stopped making the Spectre ii and Specwar, my two favorite cans. I'm glad I got them.
For small orders Access Metals is the best. They have a cutoff bin you can rummage through. I've found some really good stuff in there
They are in eastern Baltimore county, so a bit of a hike for you, but worth it.
