USM4 AR lower legit question....

[mdpatterson]

I know I have seen a question about this before, but I can't find it when I search.

The following link is to a store near me that sells AR lowers with the SF logo, and claims that it is endorsed by the SF community. It further states that proceeds will go towards "Special Forces Veterans Service Organizations".

I'm going to buy a couple more lowers and wanted to make sure these were legit prior to purchase. The huge red flag I'm having is that I have heard nothing of this company and the receiver is stamped US Autoweapons (The retail store selling them) directly below the hammer.

Any info appreciated. I would love a few dollars of my money to go to a good cause, but would hate to see it scammed.

Thanks,

Mike
