Ruger trigger (a real stretch to call it good), poor extractor, barrel clamp (why not screw barrel into receiver?), steel bolt buffer (yes, they do break), but the biggest deal buster is the bolt. It only took a few hundred rounds to find out they missed the mark. The gas bleed under the barrel makes cycling flawless. What Magnum Research didn't understand is that you can't lay the cocking handle in a slot across the top of bolt like a 10/22. Guide spring and solid cocking handle do not balance the bolt well enough through blow back and racking. The result: slot on top of bolt begins to elongate (widen), cocking handle begins to move in the slot to a point where it work hardens and breaks off right atop the firing pin. How do I know? Three broken cocking handles in two and a half years. This rifle was "babied" and only 40 grain ammo was used. I bought a Volquartsen 22 WMR. They got it right.
