Mine is an excellent shooter, and it'll throw loonie sized groups all day long with 168 Ballistic Silvertips. I have a Gen 1 gas system as well - easy to adjust but to echo what Jay says you can't juat toss anything into it and expect 100 percent function. I run mine with just enough gas to cycle the action reliably. I have had zero issues with this gun and once we're back to a double income family i'll probably treat myself to another one.
This is a robust and remarkably compact rifle. I used it last year for deer and on our first day out I received an injury to my right hand that needed a surgical repair and therfore out of commission. The next day, I swapped the charging handle and sling over to a left hand setup and voila, I was back in the game. Did I mention how ambidextrous this gun is...
The RFB is an excellent rifle, and still in good demand - so if you bought one and reall didn't like it I can't see it being too much trouble to sell it off and pick something else.
