I had a Freak for my Shocker, I'm MUCH happier with the Sly. I guess if it snaps I'll be pissed
I really like the short, interchangeable backs much better than the inserts.
I had upgraded to the Star frame, but that's only because I mangled my stock frame and you can't by them as parts
Other than a clamping feedneck I can't think of anything else I'd upgrade on this gun. I love it and still think it's a great value.
