Desert Tactical Arms showing off production models of their new line of precision rifles. Their rifles include a unique feature: you can change barrels without shifting the zero on the rifle (well, the left/right zero anyway). They accomplish this feat by using a barrel that drops straight into the receiver (no screwing around) and slots into a precision crafted groove. The system ensures that the rifle will always be firing on the same general flight path. The only thing needing adjusting: the holds at different distances. They’re also working on their own precision ammunition to go with the rifles. This could be fun.
