picked up my ab3 today. it feels really good, super solid. If anyone looks back on this thread to figure out which one they may want to get. Don't do it blindly, seriously go into a store that has both guns and feel them.
for me, the big differences that i felt had a big influence on my purchase:
the browning stock just feels more solid, less hollow, doesn't feel like a cheap stock. The ruger kind of felt like a toy compared to the browning.
the chamber on the browning is considerably bigger and easier/faster to hand load.
the magazine on the browning is made of much sturdier feeling plastics and metal.
bolt release button with the safety was really sweet, i'm quite paranoid so this was a nice feature that i didn't even know existed
recessed barrel, happy to know that if i drop the gun I'm happy knowing that the barrel isn't in crazy danger
note: i picked it up at a 569CAD price point and felt that these features were entirely worth the extra 140 from the Ruger.
Thanks for the help anyone that responded, this forum is awesome. now its time to save up for my shotgun. i'm thinking tactical... for duck hunting.
