Brendan pretty well nailed it but are you sure you want to take a gun that heavy afield? Are you sure you want the laminate stock? Do a bit of surfing. I don't know the percentage but there are reports of the laminate stocks breaking in the area of the grip.
Thanks ER00z - can I ask what scope & rings you have on them?
Highly recommend Hector’s Accurized ZR mount if you get a side lever Diana. I have one on my 52 Luxus and it’s excellent. Worth spending a little extra and letting someone that really understands that mount tune it for you.
