I bought a fake (at least I think it is a fake) Magpul M3 sling and it runs like a champ. I went to a gunshow and went to two tables, one selling fake/counterfeit products (they were upfront and honest about it) and another selling "legit" items (at least as far as I could tell and they told me as such). I compared a fake M3 sling to a legit M3 sling, and none of us could tell the difference in the actual products. The only thing that was different was that the font of the lettering on the outside of the package was slightly different on the "fake" product. We all agreed that they looked and felt the same, including the buckles.
