It's been a while since I've posted and done any real shooting but I'm getting ready to buy another suppressor. This one is going on my CMMG Guard and occasionally my Glock 19. I've narrowed down my selection to the Rugged Obsidian 9 or The Ghost SD9. I like how narrow the Rugged is, and I like the robustness of the Ghost but if I can use the Ghost on a 16" 5.56 AR platform I would be swayed. I've already reached out to manufacturer but I thought I'd start here. Thanks in advance!
