I have three favorite O/Us currently and a 12 gauge BL-4 is one of them. A Black Onyx 12 and a 101 waterfowl are the others. I have also had BL-3s (which differ only in the lack of ejectors) and a couple other BL-4s. They are as good as a factory, middle of the road, gun gets.
I had my current one tubed with thin-wall tubes. No steel, but I have other guns for that.
If you shoot it well you cannot go wrong with them. They are tough.
