hello all. I have a photo of a hk51 I found on google like 7 years ago. I now have the means to build a clone weather parts kit or a ptr or whatever. I was wondering though if anyone knew what handguard is on this gun? I can’t identify it or seem to find any other photos of one like it online. Want to build a clone just like this but for the life of me cannot figure out what that handguard is. any ideas or a finger in the right direction would be appreciated.

I posted photos of a bcm ar I was having built and one person said they would prefer to have a larger variety of firearms than a bunch of fancy ar’s and that really spoke to me so I picked up a mac 5k in ral 8000 and a century arms aes 10b2. Let the mods begin!
