thanks.

I got my upper from him, very high quality piece. He kept me apprised of the purchase and shipping info the whole time.

Highly recommended! Pete's a good guy to deal with for sure!

Look on CalGuns.net for After-Gun-Show specials he has right now. Goes by "AlohaRover" on there.

Hope this helps!

I have dealt personally and professionally with Pete for years. He's good people, and will go out of his way to help us gunfolk. Can not recommend higher!
