Speaking from past experience, they are very good shooting guns. I had one, and probably put over 1000 rounds through it. No issues to speak of.
The charging handle is proprietary, but they include several sets of ears to make it whatever size you want. I don’t recall mine being as over gassed as was mentioned earlier. I wasn’t shooting as much suppressed then as I do now, so that might have made a difference. I just don’t remember it being bad.
I have since sold the rifle, but I sold it to a super good buddy. If I didn’t like it or trust it, I would not have sold it to him.
It was a MOA or better rifle.
What I notice....and this may be JUST ME, is I really have to pay attention to my fundamentals when shooting lightweight, 16” large frames. There is quite a bit of jump with them. I can shoot sub MOA, but if I slip up AT ALL, I’ll get a flyer that opens me up to 2moa. You have to be VERY SOLID, firm, and consistent with 16” .308’s, or they will get away from you and you’ll get flyers.
My GAP-10 is much easier for me to shoot well. It’s longer, heavier, and smoother. For ME.....this makes it easier to shoot groups. But, a 22” gun isn’t a fast, handy 16” either.
It’s all about balancing the trade- offs.
