Back when Australiastill had a sense of humour, there were quite a few of the early "Sudanese contract" and later "Portuguese / Italian
Marine" contract versions here, "semi-only" of course.
Even the EXTREMELY light early pattern ones were no problem to shoot, the later variants were nicer and slightly better balanced for shooting.
I had one of each at one stage and it was interesting to get out on the range and do "user" comparisons with H&Ks, M-14s, BM-59s, SiG AMTs, FALs etc.
SiG AMT was by far the most "pleasant" to shoot recoil-wise, M-14 for accuracy, early AR-10 for "carry-ability" and L1A1 and H&K pretty matched for "ruggedness". BM-59 not a bad all-rounder
Well, that's the way some of us saw it.
