25 in-lbs for v-block and take down screws. Snug for the RSS pin, torque doesn't matter much on those due to how the force is transmitted.
I recommend never taking the v-block off unless you're changing the barrel. There's no need to do it for normal maintenance.
As for inventory... Our latest run of barrels was delayed due a nitriding plant exploding. More guns will be available across Canada soon!
