RE: Stock wood
That's what I was thinking, two or three planks glued together length-wise to make a piece thick, wide, and long enough.
Also, this would be for the model 16 Savage. I think it has a trigger guard, but I'm not sure. If it doesn't, that would be tricky.
Edit: I checked more closely on Savage's website, I'm 99% sure that rifle has a mettal trigger guard, not built into the synthetic stock.
