Well, considering they are FLM, you could say the have a perfect fit, if you know what mean
Seriously, they are okay. My mate had to put the dremel to a set once, to get the Flextek arms to fit perfect, but it was acceptable, IIRC.
I had the maxx hybrids as well, and may other FLM parts with an "almost" perfect fit. Know what you're talking about, but the Savage Hybrids were okay. Burrs in the hinge-pin holes and stuff like that go without saying
