Has anyone installed a wood stock on a M&P 10 ? I have seen an AR 15 done with walnut and it looked great. I've checked with Brownell's, Boyd, and Ironwood but no one has direct knowledge.

I don't think I've seen wood stocks on any AR-10 style rifle yet.

"Lipstick on a pig"?

The Boyd's wood works fine with a little fitting, looks great and is the lowest cost. S&W sent the spacer no charge for the buffer tube.
