Bulgy 5.56 Mag Question

[Razorhunter]

Does this seller even know what he is talking about?
Do these actually work in AR’s/M4’s/Sig 556/ or any of the other rifles he mentioned? Or, do they just insert, and drop free, but not function?
I don’t think I’ve ever seen this particular type of Bulgy polymer mag, but we’ve all certainly seen a number of different Bulgy AK mags before.
What say guys? Is this seller crazy, or dead on? He does state the mags have metal feedlips, and apparently he mentions a BHO feature as well. I had always thought, (along with many others), that the waffle mags were the only Bulgys that had steel in the lips???

They work great. The materal is not near as tough as a P Mag. But they work just fine and hold 35 rounds.
