Lithgow Arms has been around since 1912 so....not going broke anytime soon. They in the past sold .22s to the civilian market but that was 40s and 50s. They do enough dealings with other countries including refurbs of MGs etc. They also assist in the production and refurbing of weapons to the ADF not just the EF88 (Mil version of F90). The EF88 has been widely well received by the Australian Army and initial worries that it would be outperformed by M4 platforms has been rubbished. The F90 is widely 'anticipated until it's not sold commercially and then....the hate comes out. The F90 wasn't sold for 'ethical reasons' solely on the widespread use of commercially available semi-auto and autos in the USA hat have been used in mass shootings. The media and population backlash in Australia would be massive and Lithgow Arms don't want that stain on their reputation.
colt has been around even longer, look at whats happening to them. a company being around for decades does not guarantee it will be around tomorrow
