A GREAT INVESTMENT
This was, for lack of a better description, a bucket list item. My daughter wanted an AR built by me. She is a "South Paw" shooter and it is hard to find some left hand firearms for her. I put together the lower and mounted this upper to it. We function tested the firearm and that smile on her face was priceless to me! It is well built, functioned flawlessly, and made both her and I very happy. My thanks to AR15.COM for the support and Stag Arms for their efforts. If you have a left handed shooter and you are looking for a carbine length upper, I would strongly recommend this item and AR15.COM for your build.
