Uhlobo III (Izibhamu)
Uhlobo lwe-III lwezikhali eziqinile noma ukufakwa kwepuleti kuzohlolwa kusimo esinesimo esino-7.62 mm FMJ, izinhlamvu ezinejakhethi yensimbi (igama lezempi lase-US M80) elinesisindo esicacisiwe esingu-9.6 g (147 gr) kanye nesivinini esingu-847 m/s ± 9.1 m. /s (2780 ft/s ± 30 ft/s).

Ohlotsheni lwe-III lwezikhali eziqinile eziqinile noma okufakiwe kwepuleti elizohlolwa njengedizayini ehlangene, isikhali esiguqukayo sizohlolwa ngokuvumelana naleli zinga futhi sitholwe sithobelana njengesivikelo esizimele sodwa ezingeni laso elicacisiwe lokusongela.Inhlanganisela yezikhali eziguquguqukayo kanye nezikhali eziqinile/ipuleti kuzobe sekuhlolwa njengesistimu futhi kutholakale ukuthi inikeza ukuvikeleka ezingeni elicacisiwe lesistimu.Izikhali eziqinile ezigunyazwe yi-NIJ kanye nokufakwa kwamapuleti kufanele kubhalwe ngokucacile njengokuhlinzeka ngokuvikelwa kwe-ballistic kuphela uma kugqokwe ngokuhambisana nesistimu yezikhali eziguquguqukayo egunyazwe yi-NIJ ezihlolwe ngayo.
Uhlobo IV (Isibhamu Sokubhoboza Izikhali)
Uhlobo lwe-IV lwezikhali eziqinile noma ukufakwa kwepuleti kuzohlolwa esimweni esinesimo esinezinhlamvu ezingu-.30 ze-armor piercing (AP) (igama lezempi lase-US M2 AP) elinesisindo esicacisiwe esingu-10.8 g (166 gr) kanye nesivinini esingu-878 m/s. ± 9.1 m/s (2880 ft/s ± 30 ft/s).
