Excuse my language, but fuck me.
I bought 2 from the seller linked above, and two others from a small online gun store. I'm afraid they are the same. After seeing this post, i had to pull them out and examine much closer. I noticed more than what is mentioned here.
The two are in the mail on the way to me, I've asked the seller for a refund via email and will ship them back. I'm hoping he's honest and will refund the money. Will report back on that.
Anyway, let's walk through this in detail. I feel like an idiot already, so i'm doing this for the benefit of others. If it looks too good to be true, it is. My first thought after having these in hand is they are too nice, for the price I paid (online store was $100 ea, above EE post i bought from was $300/2. I thought they were NOS, which is why I was willing to ante up)
Needless to say let's put this to bed. They are fake. I was able to knock the raised C mark off after using my thumb nail, running over it. Also note keyhole forge mark does look suspect upon closer inspection.
Can confirm the actual forgings are different, Tig has a good eye:
Anodizing looks totally wrong side by side vs real colt:
What else? Notice the machining ends abruptly on the fake, and continues to the charging handle cutout:
What else? Notice the M4 marked front font is different, and appears to be laser etched possibly? The M4 on colt real is stamped.
Well, don't get taken like me. Lesson learned, and hopefully will only be $200 out of pocket as the online retailer never advertised them as Colt, thus i really don't have a leg to stand on. Hopefully the EE seller is a stand up individual, and will refund accordingly.
