Function-wise, the rifle was perfect. Thanks to all those who helped me along the way, especially @98Z5V and @Matt.Cross.
The only hiccup I had was one fail to feed with the first full magazine I put in. I stripped a round out and no problems from then on. I used 4, 10 and 17 round E-lander and 5 and 10 round CPD mags without fail.
The PA scope and Larue mount were well the money. It could not have been easier to use unless I knew what I was doing.
