I've had two - 500/416 and 470. Both broke numerous times.
Forend cracked in half. on the 500/416. Right barrel on 500/416 not bored properly, would only accept the widely-popular WR (not Westley Richards) non-SAMMI spec ammo not available on the West Coast of the US. The 470 had never been fired for regulation - they used a laser. Matter of fact, the barrels had never been on an action. POI crossed by 4.5 inches at 50 yards. After $450 spent in regulation, I found that the 470 stock was cracked at the wrist. Would have broken off within a few more shots; nice to contemplate when there's a Cape buffalo 30 yards in front of the sights.

Go pick up a Heym. The S2 is a club with metal parts. The Heym is a double rifle. I wouldn't use the S2 to hunt rabid hamsters. Both rifles went back to Blaser.

Oh, and customer service sucked!
