Most folks just use feel or an index mark to set the screw, and that works for most of em, but in real cold weather, the plastic can change a lot which would affect accuracy big time unless you adjusted the screw setting for the conditions.

Hey Tim,
I'm gonna have to call you on that one. That Survivor stock is glass filled nylon and is just about the most weather stable gunstock material on the planet! Much more resistant than any kind of wood stock and even most wood laminates!
I do agree that the screw thing is critical though. I don't really understand why the "O" ring" thingy works except that it in effect free floats the forend except, at the front of the reciever, I am not disputing that at all, it just seems to me that, especially with the Survivor forend which is WAY hollow, it might be prudent to glass bed or even pillar bed, or even steel epoxy the forend screw hole about an inch or so ahead of and behind the screw using cardboard dams, to keep the weight down (as apposed to the weight and expense of filling the whole forend) so you would have a repeatable fit which is difficult with an "O" ring given its "squooshyness?" and then use a set torque value against the bedding or use a witness mark. This would probably also mean a seperate forend for each barrel as well unluss they were exactly the same contour.
I think the problem with the Handi forends that the "O" ring solves is more of an inherent design flaw of the 2 piece stock that places an un- welcome stress on the barrel- than a matter of environmental variances.
I personally LOVE my Survivor stocks, but I can see room for improvement where accuracy and more importantly "repeatability" are concerned!
