Round table gun review’s the Obsidian Ams OA AR-15 in 300 Blackout. It’s a simple scheme. Shooters from different backgrounds get together, shoot guns, discuss guns and rate guns. Thumbs up, thumbs down or the ever noncommittal “meh” are the only options. What starts out as four separate reviews culminates in a broad overview and full bodied review of each individual gun. WE WELCOME COMMENTS! Agree, disagree, call us names, whatever you wish… we even welcome discord if it will ultimately serve the prospective buyer of these guns and help them make informed decisions.
