Well it didn’t take Chinese copy cats long to make knock offs of one of the most popular AR-15 accessories on the market. I spotted this copy of the LANTAC Dragon Muzzle brake on Amazon. It’s a pretty blatant copy, for reference here is a real LANTAC Dragon.
This isn’t anything new, EOTech, Magpul, Aimpoint and many others have had their products copied by the Chinese as well.
