Think we expect too much from the POF. POF neither has the funds nor the manpower for the R&D to ascertain which bore size of the rifle and / or of the bullet is best suited for the Pak Army. Besides, when there are so many armament manufactures already doing this work; it is far less onerous to select from one of the rifles available off the shelf which best suits your requirement. That is why so many countries are producing their assault rifles under license. Additionally, even in the case of indigenously designed rifles, bullet size is standardised to either NATO or Russian ammunition.
Ideally an army rifle should be simple to manufacture, to maintain and to train the new recruits. It must also be accurate, jam proof and durable. In other words a cheap, rugged reliable fire arm is needed.
AK-47 with all of these qualities has been available for 70 years and it has been employed successfully in Pakistan as well as in the world by terrorists & soldiers alike. POF’s G-3 has also provided 50 years of service to Pak Army soldiers without too many complaints. Therefore dilemma of Pak Army planners must be that unless the new rifle is a substantial improvement over G3 & AK-47, expense of almost $500-million for the 500,000 units is not justifiable. I can therefore understand why it is taking so long.
Benefits of 5.5mm over 7.62 are debatable in the subcontinent scenario. I came across news that after experience in Afghanistan; British SAS were considering switching back to 7.62 mm calibre. I would therefore prefer to stick with the 7.62mm.
Both the G-3 & AK-47 weight about 4.7 KG when fully loaded. This is about one Kilogram more than the US M-16. Based on Cost versus Benefit considerations and nothing else; instead of inducting a brand new rifle; I would rather work on reducing weight of the G3 & of AK-47 thru using more lightweight materials and improving the balance to minimise the recoil kick. When the best is already available, must we change for the sake of the change or simply because India or some other country is doing it?
I never had the chance of using Bullpup rifle or the shotgun; however I came across someone having an American pump action Bullpup shot gun in the Skeet shooting club that I belong. No doubt it is compact but I was told that it is less accurate and has bigger kick than the 28 inch shot gun that I have. If the same applies to the rifle, than Iranian version of Bullpup G-3 is not suitable for Pakistan.
