Blaser Rifle Configurator
Blaser have developed one of those customize-a-rifle flash tools. Very useful to work out how many of your offspring need to be sold to purchase a premium European rifle!
The interface could be improved, especially when you select incompatible options but it is still fun to use. Currently the R93 bolt-action rifle is supported with K95 single-shot rifle and the F3 over-and-under shotgun coming soon.

Don’t forget the LaRue Tactical version either-
