What guns are those in the cover of the 1988 film Operation Warzone?
The same rifle appears on another poster for a similar no-budget action film by the same studio, albeit with a different magazine. https://images-na.ssl-images-amazon.com/images/I/91+NRwnbEaL._RI_.jpg
I believe it's a T2 rifle from Australia.
Yeah, you are spot on! The image you show has the proper STANAG mag but the other posters have some strange ribbed mags, any ideas what could be these? Very obscure gun, never seen it before.
What do you think?
