Ordered on 1/1/10, came in today. Shipped promptly, got a tracking number quickly. Very smooth transaction. I initially wanted their M4, but they were back ordered. I believe I'll be very happy with their M3. Wow. An amazing piece of equipment for the price. Adjustments are are smooth and have a good feel. Seems to hold zero quite well. I have an Aimpoint as well, but I'd have a hard time shelling out for another. With the PA M3, a second one (or third!) is very doable. I have two friends looking for red dots, and I'm pretty sure they'll go this way when they see/try mine this weekend at the range. Appears to be a solid piece of gear. Got the cant mount for the M4. Hats off to the folks at Primary Arms. They exceeded my expectations. When I get the 22 LR upper for the AR, it's getting it's own PA M3. Don Wanna kill these ads? We can help!
