I've tried several picatinny rail manufacturers on my six Sako rifle. I rank ERA-TAC (Recknagel) highest.
There are two reasons:
1- Technical design providing the best grip. I have one of these on 30-378Wby which has heavy recoil compared to more common calibers.
2- Superior product support, I had problem of finding the right hexagon socket due the difference of US/EU imperial/metric sizing for the smaller screws. The factory responded with a day. (Right answer is 2,5mm).
The only thing I would change on this product is making it a quarter of an inch shorter. This way the rail length would be an exact match of the Sako receiver. However there might be a good technical reason why they designed the rail to this length which of course supersedes the visual imbalance.
For Sako 75, 85 or M995 (TRG-S) this is the best choice I have found so far. Optics trade had the best price I was able to find.
