Firearm Purchase

Purchasing firearm was easy. My local gun dealer auto filled in the purchase agreement. The firearm showed up a few days later. Paid dealer for handling purchase and that was it.

So I bought this out of a desire to expand my caliber range to the 300 BLK round as it is perfect for my purposes - and so much better for my hearing long-term with my suppressor! I already owned an AUG A3 M1 chambered in 5.56 with a NATO stock and this has been an upgrade, frankly. Every part on the gun works exceptionally well and has been a lot of fun to plink around with. I enjoy the stability of the bull-pup design of the AUG platform to get on target and stay on target. I whole-heartedly recommend this gun to anyone without hesitation. There are only two drawbacks, in my opinion. The 1.5x optic is OK but I quickly changed it out for an Eotech Holo and STS magnifier put on a Corvus replace upper rail available on the Steyr website as this is what I normally use. The second concern is that finding a "Steyr Standard" (waffle) mag specifically for 300 BLK, which is what this ships with, has been an issue that I'm hoping will resolve soon.
