I purchased an Aimpoint with tri-lock mount, seen on this board at:
AR15.com Aimpoint add

Received the scope today and it is wonderful, big time +1 to the seller for giving a great deal.  I thought it may be risky since the seller had a low thread count and was across the U.S. from me... but he was AOK, even sent the scope before cashing the personal check I sent him.

Was the obvious reason that there would be too much traffic on such a deal?

Thanks alot to the guys who answered below for all the info... I have never participated in a thread that got locked before.  Did not know what to think, so thanks for giving me some AR15 - 101.
Good idea about editing the for sale post and not reposting a new reply... Infact, I did that just now, I was going to reply... I'll look out for that.

Thanks again.

As far as I can tell it was locked because the scope was sold , to you. It's common pratice to remove/lock an add when the item is sold. Free up extra space ya know?
