I'm shooting an LR308B (18" bull barrel, free float tube, railed gas block). I've had a great time shooting it, have taken 3 deer with it, but with the weight, it would not be my first choice for long range stalking or hiking. In the stands or condos I've used, weight hasn't been an issue.
It's topped with a Nikon Buckmaster 3-9X40 BDC. I've really enjoyed shooting it while using the SpotOn software.
I replaced the stock trigger with a RRA 2 stage. MUCH better IMHO.
Shooting Hornady .308 150 grain interlocks, I get about an inch at 100 yards. It could do better, but the trigger actuator has some limitations.
