I'm sure the Mauser is a fine rifle and very strong. The implication that a Blaser is unsafe is a bit erroneus. Tests have been done with overloads on various rifles and compared so some other well known brands, the R 93 did pretty well.
The only Mauser I've had was a military surplus 7x57 Mauser I got at Montgomery Ward for, I believe, well less than $20. The barrel was pitted and the sights weren't that good. I'm sure they've come a LONG way since then. I do have a couple of Blaser R 93 rifles and can highly recommend them. Right out of the box, they'll feed slick as snot and the trigger is excellent. For me, accuracy has been excellent except in one barrel that was replaced with a new one by Blaser. When you remove the barrel and scope, you can easily get the rifle and a handgun in a gun case that complies with airline specifications for standard baggage. Removing and remounting the scope doesn't change the point of impact.
Despite all their excellent qualities, there are some things I don't like about Blaser. Except for their 223 Remington barrels, all of their .224 barrels have a stupidly slow twist rate of 1:14. Also, instead of having the sling swivel stud on the bottom of the forend where it can be used with a bipod, they have it on the end; if you don't use a bipod that's no big deal. If you get one with iron sights, the stock doesn't make my eye naturally align with them; maybe your face is different. Also, Blaser has stopped production of the R 93 and support of the R 93 will be ending as well if it hasn't already. I have an issue with a company that sells an expensive item and then abandons its customers.
If I were buying a Blaser now, it would be an R 8; it should be another 15 years anyway before Blaser comes up with a new model. I'm quite satisfied with my R 93s which should last me until I die.
By the way, I believe the prices of a major purveyor on gunbroker.com are a bit high. You might try priceing a Blaser or Mauser at Eurooptic.
