I agree with this, but I don't find the FNAR terribly difficult to strip and clean. Sure, there are many rifles that are easier, and it has to be an understood compromise. For me, 2-3 MOE from a CETME is not acceptable when I can get a rifle that will do 1 or less consistently. Folks have different needs, and it's great that we have so many choices.
Compared to an AR.. Ak.. H&K G3.. SCAR.. or even any belt fed I own... compared to any other centerfire semi-auto platform I own, it's far more complex. Anything that involves punches and screwdrivers and levers and sleeves and stuff is complicated.
While THR has rules against the "SHTF" type threads, if anything ever DID happen, the FN-AR would be the LAST rifle I would pick up out of the safe to take with me. I can't stake my life on something that has a 7 minute dis-assembly process, on a bench, with the correct tools at hand, and a half dozen small parts to lose (some of which are under spring tension).
Heck, right in the owners manual it says, essentially, "stop here, and send the rifle in every 2500 rounds to the factory for detailed cleaning and inspection."
Don't get me wrong, it is a fantastic rifle, extremely accurate, and I love shooting it. But the complexity of it is a turn off, from an "end of days" perspective.
Granted, not everyone looks at things that way, or cares, but there's another concern for long-term thinkers. Spare parts for my grand children. If something breaks, will FN still be around? Will spare parts even exist? Or will it become a 7 pound broken-down gun that's not pretty enough to use as a wall hanger?
*IF* you already have a reliable, great shooting 7.62 and want something that is highly accurate and has rapid second-third-fourth-twentieth-shot followup times
, the FNAR is a great rifle to add to a collection. But I don't envision it ever serving a role as "primary" battle rifle, due to the above concerns.
While I personally don't like them, that's one of the major advantages of the AR-10 platform. Every part in them is user-serviceable without armorer training, and supplies 100 years from now are unquestionably going to be there (if society still stands, they'll still be in production; if not, there'll be tons of spares out there in circulation). That platform is not "going away".
The CETME / PTR-91 loses some points there, mainly because the *barrel* assemblies are a real nightmare to replace. It can be done, but not without a hydraulic press for the pins. The AR-10 wins hands down there as you can swap the barrel with a vice and the suitable wrench.
The SAIGA 308 route .. meh. It'll put rounds downrange but not with the same precision as the others.
