Little misleading - CAA Micro Conversion Kit for Smith & Wesson M&P 9/40/M2.0

Well I ordered this for my M&p under the impression it’s the newest version of the conversion, however apparently even though it’s advertised as “gen 4” it’s just a gen 1 that’s been modified to fit the M&p. Wouldn’t be a big deal if that was stated anywhere at all on the page but it’s not, so you get the old brace that does not allow folded firing and use of some of the new attachments they offer doesn’t work. Trust me I know after waisting a ton of money on accessories that don’t fit properly and being told by a caa employee that this is a gen 1. Definitely misleading by optics planet. Thanks
