I purchased the official Freedom Ordinance extended charging handle and was not pleased. Ended up returning it. It was slightly larger in the hands, but it didn't fit the rifle. It scrapped along the top of the buffer tube, and now I have an ugly mark along the top of the firearm. Not a huge deal, but overall it was disappointing that a company's own accessories don't fit their own rifles.
Other than that problem, the gun has worked perfectly with 4.6 grains of W231 behind 115 rn (the same load I use in my Walther Q5). I was on this thread looking for aftermarket trigger options. Sounds like the CMC 3.5 is my best option, as I am not shelling out Hyperfire money -- unfortunately.
