About three years ago, when I was still relatively new to AR's, I purchased, from a "friend" a "Pre-ban" (according to him) Colt 20" HBar marked "Sporter Match HBAR". This rifle came with an A2 bircage F.S., has the sear block, and no bayo lug. It was Brand New/Unfired (and the price was right-$1150), so I bought it from him and also got a letter, with stamp and all, confirming its pre-ban status. Here comes the kicker: EVERY website (Biggerhammer, etc.) states that the pre-ban Sporter Match HBARs last serial # was MH086020, MINE is #MH087XXX. I even called Colt and they assured me that there was no way this could be a Pre-ban. Now I don't know what to think because I got this gun from a friend and co-worker (who used to work for Colt, and also whom I feel would not try to knowingly screw me), and I have this letter from another guy from Colt who assured me that it IS pre-ban. Does anyone out there have any knowledge about this type of thing, or even any personal experience????? Thanks in advance for any info. If it is NOT a true pre-ban, I only have myself to blame for not doing more research prior to my buying the gun...live and learn I guess.
