Another alternative is the Klarig muzzle brake from Germany: https://muendungsbremsen.de/en/borelock-brake.html
This is compatible with the Ase Utra Borelock system, but is much more compact and neater looking than the Finnish made brakes. However, fair warning, Klarig does not accept credit card payments, insisting on the SEPA bank transfer system. I found this pretty complex and managed to mess it up. However, the quality of the brake itself is top notch, with excellent machining and a Nitride surface finish.
