These magazines work perfectly in my 6BR built on a Tikka T3 action set into an MDT Oryx stock and are made of metal, Not plastic and are spacificlly designed for the range of 6BR based cartridges.
Double stacked but with center feed so the round goes directly into the chamber, no spacers or modified lips, they just work and this company does a whole range of of magazines for lots of rifles aside from the AI/AICS format.
6 & 10 round capacity and even a “sled” for single shot.
