Fair warning, I could be wrong on some of these details, but this is what I remember from talking to them.
There is a functioning prototype of the AICS magazine for Tikka. I shot it two years ago and then earlier this summer while at events with Tikka. Right now it’s a 3d printed prototype but they are planning to produce it and I believe they said it’d be available in January.
I don’t know if it’ll be regular AICS long, or CIP length.
