Perhaps your sources are misinformed.

David, I think you're misunderstanding.

I'm agreeing with Jeff that the stock is indeed of monocoque construction as it leaves the plant in Costa Rica. You were disagreeing with that statement, at least in terms of how I understand the English language.

Beyond that, I'm not debating anything. I've never opened one up, though I don't see why it would hurt as long as the barrel channel is re-glassed.


Brad,

Someone may be calling it a moncoque structure, but it is not. A stressed skin / semi-monocoque, no problem. Certainly I believe that disrupting outer skin structure in places will have negative impacts on strength/rigidity. Opening the barrel channel does not, hence by my understanding it cannot be considered a true monocoque structure. Certainly in the context that Jeff was referring to, that the barrel channel cannot be opened up because it's a monocoque structure.
