Great for a build

I waited to try a new caliber rifle. I was impressed by what I was hearing about the 22 Nosler and wanted to try it out. I decided to build my own since I doubt that Stag is going to offer this caliber anytime soon. All of the other components fit nicely with this upper and look great. If the rifle shoots as good as it looks I will be pleased.

A3 flattop upper

As always a great product. I was wondering why SA is not forged into reciver that might be reserved for complete rifles.
