An Airsoft gun maybe. The AUG is the only common bullpup in this country really and they have almost nothing in common.
The L85A2 has supposedly fixed most of the L85's issues, but I'd doubt that without running at least a thousand rounds through one myself.
"And Shepherds we shall be. For thee, my Lord for thee. Power hath descended forth from thy hand, that our feet may swiftly carry out thy command. So we shall flow a river forth to thee and teeming with souls shall it ever be. In nomine Patris, et fili, et Spiritus Sancti. Amen."
