RA-Tech review the Open Bolt gas blowback rifles made by WE such as the HK416, CQBR, and the M16A3. Also part of the review is a preview of their new product, the CNC steel trigger set for the WE SCAR and WE Open Bolt kit. They even added a nice touch by changing the venue to a home bar. I wonder if they've got some ale or whiskey there while doing the review.
