This is my B-Barrel with a Weaver 4X LER scope. I really, really like this rifle. It is heavy, no doubt, but I'm a big guy (6'1", 190#) and can handle it. This was basically a U-fix-em that I got from WG&A, and I cobbled the parts together. The metal (barrel, receiver) was in new condition, but I needed to find a new stock. Worked out well in the end.
To answer someone's question, if I place my hand directly in front of the magazine floor plate, so my pinky is touching the front of the magazine base plate, it balances when I hold it right there.
