Thanks Headbar!  That's easy to understand.  If I remember right, I pull the lever DOWN and slide the stock off the tube, and then I should see the flat or slanted end?



Thanks for the welcome, too.  Member of many sites, but new to ARs.  



I bought a used/exc Core 15 M4 Scout before Christmas and promptly went on vacation without firing it.  I stressed a little over the mixed reviews I read while away, but when I finally got to function fire it (on a snowy roadside, no paper targets) I was happy.  No hiccups.  I had put a good quality rear sight on the flat top receiver and the water jugs disappeared as expected.  Can't wait to shoot for group and see what it will do.  It came with green parts, which don't thrill me, but I felt like I was racing the White House at the time, so I didn't worry about that.  Would love to float a forearm eventually and throw an optic on it, but I (and my wallet) like iron sights for most things.  I'm learning a lot here, and again, thanks for the welcome.
