designs like the ACR, SA80, FS2000, AUG, Tavor, all of these are more complicated to strip and put back together and none of them use a piston to my knowledge.
Actually, all of those use pistons.
It would be cool to see the Bermuda Mini's on the US civilian market, but I don't think current US law allows them to be imported. I guess I am not sure, since they don't have the dreaded evil death-dealing pistol grip. Maybe they can be imported, just like "sporting" Saiga rifles from Russia.
This is the first thread that made me think about the Mini's accuracy in terms of military requirements. We hear how the earlier ones were not very accurate, but compared to an AK? Plenty of armies were and are satisfied with the accuracy of the AK. So maybe the Mini wasn't so bad.
