Just curious about this barrel band

[Jet Fixer]

It's a good copy. Even if it was real I wouldn't buy it from him, just on principle. Before I found some of these forums I bought some of his stuff. All of it later turned out to be repro. It's now on my Auto Ordnance carbine because I couldn't bring myself to throw away $200+ in parts. Live and learn. Expensive lessons though.
