And that was just 3. I don't see any problem finding them. Just a quick Google search. I've bought a few stocks from Brownell's before. Never had any real problems other than just fine tuning stuff. Little trim here, little sanding there, pretty much all the same thing from anywhere unless you send the rifle in to be mated.
