Invitation declined. I don't hate SCAR. Do I think it would have been the best choice should Norway have floated a tender? No, I don't (and I don't think it's the best option for Pakistan either). But Norway never got a chance to test it against the HK416 or HK417.
SCAR first showed up in 2004, but only just entered a limited production run in 2007, to trial the rifle and work out some problematic ticks. By that time Norway had already selected the HK416 as its main service rifle to replace the AG3. SCAR's problems weren't resolved until 2009, and it still has occasional issues like bolt seizure or frame cracking in cold climates - the HK416 had these issues too, but a Norwegianized, Winterized variant called HK416N applied fixes to the base design to make it more suitable to cold climates. The HK416K carbine also applies these fixes.
The rifles, HK416 variants and HK417 have gone on to serve in the Indian Ocean, in Mali in support of UN operations, Libya, Syria and Iraq where Norwegian special forces and police and military trainers continue to operate, Afghanistan, the Balkans and Baltics and Norway itself. They work in the cold, the hot, the high altitude, the humid and all conditions one would need a rifle to work in.
While USSOCOM adopted the rifle (all variants) in 2004, it was to trial it in-field, same as what Norway's KJK did with the HK417 in 2007 (shown below). USSOCOM didn't field the rifle until 2007 and didn't formally accept the rifle as operational until 2009 after extensive testing. They then dropped the lighter SCAR-L, retained the SCAR-H (with a conversion kit), but don't plan to continue to procure either type.
Rather then hate SCAR, I feel that because of its problematic development and ongoing problems it wouldn't have been the best rifle for the Norwegian Armed Services, especially given Norway selected its primary arm a full two years before SCAR was officially operational.
SCAR wasn't given a chance to prove itself in Norway and I have my suspicions it wouldn't have measured up to the HK416 or HK417 anyway given its complicated history. Unlike the HK models, SCAR variants still have cold weather performance issues.
