Great looking, but mind the size!
The outer diameter is 0.9" at the gas block. This is not listed on the manufacturer's web page, so I thought I'd put it here. This also explains why it comes with its own gas block. Don't expect to re-use any mounting hardware, or piston kits for that matter. I'm giving it 4 stars for not providing very basic information like gas block diameter. Ultimately, the purchase was my fault for assuming this was a standard 0.75" OD tube, and is why I had to return it. This is a high ticket item, and customers deserve to be informed.
