Well they are very short-26" oal with a 16" barrel; of course that is a bull pup characteristic. The big time internet reviewers give them very high marks(MAC, Nut n fancy, Hickok 45, Miculek, Fortier, and others). The obligatory cons seem to be less than stellar trigger and not as dead accurate as a typical 'good' AR. Handiness, reliability, ar pattern mags, compactness, combat proven, easy stripping, barrel change kits, and Star Wars cool seem to be their strengths. Seems like it begs for a red dot sight to make it an ideal homeland defense rifle. Anyway I will know more soon.
