First, I rated this at a 4 only because most folks now days want light as a feather. This mount is not the lightest out there. That being said, I actually don't have an issue with a couple extra ounces especially when the craftsmanship is as good as this mount it. It has an easy enough tension adjustment that just a tad finicky but once it's set to your rifle, it's there in the exact same spot on and off the rife. Very well machined as would be expected being of Polish manufacturing. F.B. should watch out for this class of firearms. The quality is as nice as what I've seen in F.B. Radom, no joke. If you don't mind a little extra weight, I would 100% recommend this for a side rail mounting solution. Hope this helps

Well worth the money must have. Don’t waste your time buy now
