Hello
From my personal experience, I highly recommend them.
They go to the Harrisburg, PA gunshows from Il. They always have a ton of good stuff with good prices. They are always friendly and helpful. My buddy and I usually spend at least $100 with them at each show. 2 shows ago I wanted a 9mm set up for my SBR'd lower. They had all the parts (upper, hammer, buffer) except the mag block. He made sure I got the block within 3 days and sent 2 T-shirts. They also gave me one heck of a "package deal" that day, so I bought even more stuff from them.
Good group to deal with.
