I just bought my 13 1/2" Diamondhead VRS-T hand guard for my next build from them. They were the ONLY one I could find who actually had it in stock. And their price was better than anywhere else. To top it off I had it in just a few days. So I've only had a positive experience with them.
"No free man shall ever be debarred the use of arms. The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government"
