I came across this on Wish.com. Wish a site that sells Chinese items which are shipped direct from China. They're very low cost items, generally because the shipping time they take to arrive is usually considerably longer than westerners are used to. I found this and similar items. Muzzle Brake Compensator 9mm 1/2x28 TPI 7 Inch Length Black 7075 Aluminium CNC Recoil It's $46. I'd just post a picture but the site won't allow me to get the url of it's images. They also sell similar designs in 5.56 and 7.62. https://www.wish.com/product/5b431a9ed9b2a407d6ecc525 Is it me or does this look an awful lot like a suppressor without the outer tubing? Anybody have an opinion on this?
