Different anon here, I can tell that its not HK but not specifically PTR but I'd also believe it is.
The grip material is matte whereas HKs are glossier. It also looks like its made of a different kind of plastic. Additionally the font of the selectors looks off somehow so that also stood out to me. Oh yeah and the rollmark. Shame the SP5's rollmark is fucking stupid.
Picrel is an HK-94 with the same model of pistol grip and fcg.
