$3000+ price tag on that sweet boom stick....

I think you'll have better chances of saving more money building it yourself. get yourself a SAI Scout for $1300 and buy the EBR stock for $700 and that's probably priced brand spanking new. I've seen SAGE stocks sell as low as $600 in pretty mint conditions.

Other than that... I think Fulton makes really good M14 parts and M14 rifles. I've read a couple of good things about'em and haven't seen any negatives about'em, but I could have missed a few reviews.
