Once again, we hear the argument that the Galil is not used because the M16 is cheaper. Of course, this argument ignores one thing: the facts. The Galils are sitting in the warehouses, available for use. Given that Israel has a manpower shortage in the military means that those Galils not issued immediately are available as spares. So why oh why are they not using those weapons, which they have freely available and for which they incurred a large expense Why are they spending money on our gear? By the way, yes Israeli does get aid from us. But, does no one stop to wonder why they spend that aid on M-16s rather than high-tech gear which is more expensive? It's a bad return on their, our, whatever investment?
The simple reason is that the Galil is unsatisfactory for their use. It is considered as too heavy for a 5.56mm, and is prone to microfactures in the barrels (according to the IDF at least).
