I'm with ruraldoc on this one.
I've had A-Bolts since they came out. I've fallen down scree slopes, into rivers, off of logs and dropped mine more than a few times. I am NOT a cleaning fanatic - in fact - I'm more of a "shoot it until I have a problem" kind of guy.
Not one of my A-Bolts has EVER failed me - in any way.
I wished I could say that about some of the other brands I own. Hint - one of my worst brands that I own in regards to needing visits to the gunsmith - is the darling of the "modifiers" - you know - the brand that everyone takes to their gunsmith to get them they way they want them - and then raves about!
Not only have all of my Brownings been trouble free - they have all been accurate - BEFORE - a trip to the gunsmith - not like that other brand.
