I've owned two Blaser S2 double rifles. Both have been returned to the factory.

1. The 500/416 broke its forend within 4 shots. It would not chamber any other ammo in the right barrel other than WR. Blaser had it two times and never got it right

2. I swapped it for a 470. It was cross-eyed by 4.5 inches at 50 yards. My favorite Greek up at Heritage Arms in SLC regulated it for me. Ask him about the guy from Nevada and his 470. When I next took it out to shoot, I found that the butstock had a radial crack around the wrist. Gun is GONE! I had other problems with fit and operation - see if Heritage will tell you about the grease they cleaned out of the locks, or how the barrels would not fit into the action without work.

Go buy a Heym, or a British double. Shoot it before spending money. I'm involved in buying a Heym 470 as we speak.

Everybody above who said the same is right.
