As Dean2 said, your response is evidence that you have not read the thread. It is okay to be a Larue supporter. They must have few to still be in business. The worker's patriotism is not in question here.
I have had literally dozens of rifles over the decades. I have never had one that would not function reasonably well with common military accepted gear such as AAC, Surefire, etc. My AAC MK-13 actually tightens up groups out of my 308 custom bolt gun. I shoot it on the rifle all the time. My Noveske M4 holds point of aim and still under one MOA with the SureFire SOCOM break and suppressor. And, so on.....
A lot of those who are not in the know, look down their noses at re-loaders but, in some sports, it is practically required. PRS and IDPA come to mind. I will include a tailored 5 shot group of the load I developed for my PRS competition rifle. No factory ammo can touch it.
Nowhere on Larue's web literature do they describe the utter proprietary nature of their firearms. Nor do they prohibit the use of reloaded ammo. Nowhere, at least not when I bought this rifle. We all know that AR10's are not exactly "mil spec" but, when a broken firing pin retaining pin (cotter pin) keeps your rifle dysfunctional for 2 over two months, there is a problem in my book.
When it takes over two hours on hold on any given day to talk to their one and only customer service rep and, for him just to tell you that there are NO parts of any kind available, That is a problem. This was all before America melted down over COVID.
Also, as I said earlier, Larue does not stand by their products.
They refused to take the rifle back or exchange it. Believe me, I tried. You enjoy your rifles. I will continue to support KAC, Noveske, LMT, FN, Colt, and others that just work. I just picked up a FN SCAR 20S in 7.62 a couple of weeks ago. Still waiting on a BGC to complete a LMT MWS build. These rifles are "Multi Cal" and have factory and custom aftermarket barrels that are user interchangeable.
