Well, I've got all my paperwork in, and now I have to make a decision. I want a dedicated 9th suppressor, and I'm torn between the swr octane, and the griffin revolution.i believe both are comparable in construction and materials, but the griffin has the added feature of a "k", or short configuration. And although the price is right on the aac tirant, I don't really want aluminum k baffles. Any experienced folks here wanna chime in? Thanks for any info guys.
