This stock is brand new, just arrived from Manners. Unfortunately I ordered the wrong barrel channel and instead of opening it up, i'm going to order a different one. The stock includes two, un-installed aluminum pillars from Manners. See the build sheet for the specs. Pics to follow. I realize I don't have any feedback here. I have been reading and absorbing information from the site for some time and not doing much buying/selling/posting. I can provide feedback links to my profiles on other sites upon request. They are all 100% positive. Just looking to get my money back on this one, $800 shipped/insured. Post Office Money order preferred.
