The RFB is more of a DMR type of thing. This G3 Bullup looks like it was designed for CQC.
If the G3 bullpup is in 7.62, It's a bad idea. If it's in 5.56, It's a good idea. I think it is the latter due to the curved HK53 Mag in the picture.
The Iranians make alot of silly stuff which most of the time have no practical use, But they gain experience from that. And after making alot of silly and usless stuff, they come up with something badass like this 12.7mm Gatling gun "Muharram"
