It's a just a communications faux pas. Marketing flaw. You made a claim that you can't back up. I believe you in what you say about the specifics of the arrangement. I don't think you had /any/ ill intent here and don't think any worse of you or your parts. I think you probably just learned something about advertising/marketing/communication though, in that you can't (easily) make a claim without substance.
If you had just said you were putting together Ferrara Firearms LPKs and wanted to know what people wanted to see in it, it probably would have gone much smoother. You started talking about other companies' practices and products, probably without thinking about whether you'd have to explain that or not. But you tried to build your product by saying you didn't want to make the mistakes others do. You left questions that you couldn't answer and it just makes you look bad even when you're not doing anything bad. Appearances... that's all.
One thing I've learned is to never say one word beyond what is concrete. Don't compare myself to others. <This> is what I do, and <this> is why it's good, and <here> is what it will cost. If you aren't happy with that price point, I can offer <this> product which still performs in <this capacity> but lacks <feature> which reduces the price.
All of the above are things that don't leave questions. They don't bring <other products/companies> into the mix which put me on the spot to talk about other companies, which, if it's anything other than respect or flattery, will make me look petty and slanderous. But if you only praise other companies, how can you say your stuff is better than anyone's? You can't. It's a no win. So I don't bring up other companies. There are concrete factual claims such as lead times that are neutral statements. "They're great stuff, but right now their lead time is about 8 months. If you want something now I can make that happen, if you don't want to wait the 8 mos for <company>" - it doesn't speak to their quality or performance, only stating a logistics fact.
I think you're getting nailed here kind of hard for what it is, honestly, and I hope people see that.
I mean, it's not like you're doing a Mark LaRue, here.
Exactly what I am doing, having some parts branded, some of it OEM sourced is going to save money. I could have just bought the ALG defense kit with a branded LPK but didn't want to use that brands LPK's based on their reputation on the FFL boards. I found kits with good reviews both by customers and dealers, and got some quotes. One of the distributors said I can't put that together for you, but these guys can, here is their info. It just happens that the place I ended up using is the same company that makes the kits for some very well known companies that are the same ones I was considering buying at the wholesale level.
The only claims I made was that some manufactures don't care where the parts come from and that some parts on the market are out of spec/backwards engineered and I wanted to avoid that. In the end, I feel my customers will be happy with the quality and price of the kits, especially with the Ferrara Firearms lowers and couple of other lower projects I have in the works with branded with other organizations logo's.
