A couple months ago I helped a cowboy action friend change out a fixed buffer tube/stock on a Carbon 15 he bought on the cheap to use for a truck/beater gun (he has other nicer ARs) but he had no castle nut wrench or vice block, so I brought my portable vice and everything else needed and changed everything out before we had the CAS match that morning.

This morning at the target setup for tomorrow's CAS match...he came up to me and said he has something for me and gave me four 20 round Colt .556 magazines (UI stamp on body)...he said that he had these since he came back from Vietnam in 1971. They show some use, but are in very good condition.

It was a nice surprise

Good Karma for helping your buddy. Congrats.

Good things happen to people that help each other out. Every time you see or use those mags you will think of that day you helped a friend out. Priceless
