I also looked a lot at BRX1, basically I could get three complete rifles for the price of on R8 with two barrels. And I'm a leftie so not much to choose from.
Liked BRX1, BUT, I wanted .243 and couldn't get that last year, and wanted 9.3x62 which is not (yet) available. And now I want .416 too, so happy that I didn't go the BRX1 way, but not because I think it's a bad rifle, but like being able to add.
Also looked at Tikka T3x CTR, fine for .243, but for 9.3x62 had to take eg Lite, so not exactly the same rifle. And nothing bigger than 9.3x62.
So ended up with blaser. And very happy, the biggest purchase I've ever done besides property, and don't regret it for a second.
