When this issue comes up, it becomes a matter of definition & understanding.
For those who don't know any different, the FNAR profile may look like a military-ish rifle.
Typically, military rifle designs are created & manufactured with the ability to do easy take-down, cleaning & maintenance in the field, among & amidst all the gunk & mud & blood & rain & snow & dust that a battlefield may produce & provide.
The FNAR was built as a semi-auto precision rifle, mostly for urban (LE) or range use, with a side trip or two into the hunting season, if you want to tote the weight.
Assuming it could & would be taken into a calm, warm & dry environment for thorough cleaning after & between uses.
Being based on the Browning BAR, it does not break down easily for field (or anywhere else) cleaning, as a true battle rifle design does.
The ubiquitous AR-15, for instance, and its arch-rival, the AK-47, both break down in less than a minute for cleaning & maintenance, anywhere, in just about any conditions.
Same with FAL, AUG, Tavor, H&K 91/93 & clones, and other current military arms. Also the same dating back to the bolt-action days with Springfields, Garands, Mausers, Enfields, Mosins, and so on.
Very far from the case with the FNAR.
And it was not built to handle the battlefield as main battle rifles are.
My point was that if anyone looks at the FNAR, thinks "battle rifle", and buys one for that role, he or she may be disappointed.
And before you ask how I know what the intent of the model is, I discussed it with FN when I wrote up one of the first ones out.
That's the niche they see it occupying- precision rifle for LE primarily, hunting & range fun secondarily.
Yes, you could take it to war, but other designs more easily maintained would be better choices there, most especially in a long-range context.
Poor choice for standard infantry, semi-auto .308 is not a huge boon for 500-yard snipers in a military context. If it were, you'd be seeing them fielded.
Ya want one, get one. It's a good rifle.
Just saying understand what it is & what it isn't.
