The beeman version was called a R1 super magnum but would be beeman stamped !
The solid breach face means it's an older barrel and that's not a bad thing!!!
It's a HW80K with a newer beeman stock!
And the barrel's on a 95 and 80 are the same....will interchange from one to the other. Even the cocking arm!
Nice gun and if it was that loud it was dieseling a little..shoot it some more and that should settle down.
