I have these on all my rifles
You can put a piece of foam under to adjust your comb height and carry extra ammo either inside the pouch or in the shell loops on the outside.
I carry an extra loaded 5 round magazine in Mine that I have on my
Tikka Superlight.
Attaches securely to the stock
Cant beat the price
