Let's see, there's the CP Pro, Dark Series, new style All American, and JT kits that work like it (the CP is EXACTLY like it and came out years before) and the JT, stock Timmy, and DYE barrels that look like it. It's ridiculous. Any other business would declare it a patent or copywrite (in media business) infringement. It's downright shameful. The fact that it's commonplace in the industry is appalling.
