. Now if we are going to test 4 to 5 new Guns in round II along with FN SCAR than in entire world I can only see HK-417 which may come close to FN SCAR in performance in all aspects.
No, you're comparing dissimilar guns.
FN-SCAR is an assault rifl
e and behaves like one. It has semi and full-auto and controllable recoil. It's light, compact and easy to maneuver in tight spaces.
The HK-417, which I had the pleasure of using during my time in the RNoAF during aerial shoots, is
a battle rifle and is typically used as a designated marksman rifle:
While both have longer or shorter barrels depending on the requirements on the individual military's, the HK-417 is less suited to assault duties due to a heavier recoil and a higher weight, which drags on a soldier.
The HK-417 is used as a long-range precision weapon, as fits its traits:
Even when using a smaller barrel, it's still better for DMR duties, as opposed to SCAR which is best as an assault rifle and has a secondary DMR capability with the Mod 20 configuration:
The two guns share the same round, but one is better for assault duties and is an assault rifle. The other is best as a DMR and is a battle rifle.
They aren't really comparable. HK-417 is a straight improvement over the G3 (AG3 here), as the G3 was also a battle rifle:
But SCAR would be a shift away from the battle rifle type in Pakistani service and a move towards a more conventional setup for infantry units, as it's an assault rifle.
