its the new SA80, the British army calls it the L85 though.
How has that gun not gotten on the ugliest thread? All bullpups are for dirty Europeans, uneducated conclusion

. FN has done the best on bullpup IMO, clean, sleek, and lean. The Euro military weapons are just visually offensive, do they work, don't know personally, but I'm going to continue shooting rifles thank you. They work well if you've got a bunch of folks that can't shoot far. Make a good crew issued weapon for those that don't find themselves flying through magazines or putting fire down three hundred yards away.
I tell you though, I'm a bit uneasy about the bullpups that don't have the trigger guard over the actual trigger, like the AUG.
