Used both extensively, and IMHO the AUG is superior in every way to the M16/M4. Modularity, user-friendliness, ease of maintenance, and AK47-esque reliability would make it my choice, hands down, over anything else, esp in 16" version. The only advantage I could think of that the M16 type would have over the AUG is the fact that M16 mags are much more readily available. BUT, now that there is the M16 conversion stock for the AUG.....the possibilities realy are endless.ministerofdeath said:Just wondering how AUG really stacks up against the M-16/M-4 variants. If anyone has real world experience with both 5.56mm assault weapons I'd be happy to hear your personal opinion as to which one is the better SHTF weapon.
