Mountain tactical has magazines

They are fine and affordable, the best are from https://watersrifleman.com/magazines/

I have 2 Tikka CTR models.

They come with a 10 shot double stack mag.

I have not seen or heard of a 5 round to suit the CTR as they use the double stack.

There is a 5rd factory model in single stack for sporters

I think these Were the same magazine that was used in the Sako TRG models.

The Waters Rifle man magazine that I have is 8 or 10 round. They are single stack and fit the sporter rifle mag well.

I hope this helps.

If there is a 5 shot ctr mag I will look into it. My first CTR is in 7mm-08 and it’s great from the car.
