You have to realize that the Abolt is a nice looking rifle - especially the medallion. Hinged floorplates or no floorplates are by far the nicest design appearance wise if you ask me. Browning went for appearance but also function and therefore they got the best of both worlds if you ask me. Beautiful hinged floorplate appearance with magazine function!
The magazine clicks in exceptionally well and swings right up into the gun. Looks like this.

I own 2 abolts and have nothing but good things to say about the system. I dont want to stir the pot or anything but I think the Abolt magazine system is much more user friendly compared to a tikka t3, savage, and those rem 7600/7400's. (What I am saying, is that you never have to fiddle with it, it might take a few seconds longer to put in, but it always goes in right, I've had times with the guns mentioned above that you have to make sure you put the rear end or front of the mag in first, then snap the other half up and in, sometimes it doesn't latch and you have to smack it or take it out and retry etc etc... the abolt may take a little longer, but they system doesn't require the fiddling, it goes in right every time!)
The thing I find funny, is if you ask what is the best semi - the Browning Bar is proclaimed as the top of the line. Not once on a Bar have I read a complaint about the hinged/detachable magazine system, but I always hear that it is a fault on the Abolt.
