That's what we're here to discuss. Having said that, while the Tiberius adjustable riser is great for mask clearance and shot adjustment, it's one click increments are rather extreme and the piece itself adds a largely noticeable amount of weight to the rifle.
I have about 40 yards on the side of my house to mess with. At that small a range, a single click on vertical adjustment changes drastically (the Tiberius riser). I'm hoping to do field proofing tomorrow (considering I can get out there) and get some actual trigger time to familiarize myself with what I have.
