It was later on when they looked to sell that they started creating more IP and trying to get trade dress on the look of their guns and even trademarking the "sound" an autococker made when shooting.
I am not aware of any IP that would stop someone from making a gun with a back block, but if there is I would love to see it.
Also when did the Sniper first get released? Since that had a back block and would have been prior art any patent would have had to have been filed within a year of that being shown or be invalid.
I don't, and to be honest, I may be passing on anecdotal information. And you are very right, they probably TRIED, but were unsuccessful. I just remember reading, on several occasions, that when the legal battle started they used the presence of back block in an attempt to claim infringement from the Illusion.
