S.W.A.T. Firearms Receivers - any info?

[Dave Berryhill]

I recently received an email from a company called S.W.A.T. Firearms with a brochure about their billet lower receivers. So far, I haven't been able to find any info about their quality.

I'm just curious if anyone have any info or feedback on them?
