I doubt you're planning on humping this through the Outback, so weight probably isn't going to be a huge deal, but I do have to ask which stock you think you're going to "stick" with? Personally, I liked the factory folder I handled at SHOT 2015.
not sure yet, haven't had enough time behind the xlr to tell if i like the additional rearward weight, It's a very high quality stock with a metric ton of adjustment though. ya, it is a little on the heavy side, but the barrel is also a pretty heavy profile, nearly a pound heavier than the factory barrel.
