I know this isn't exactly what your asking but the point is the same. I made the same mistake a lot of people do and as soon as I sunk a bunch of money into my first AR I went out and bought a $40 .556 rated red dot. The FIRST time I took it to the range I got less than a magazine through the dot and it started flickering on and off with every trigger pull. It made me realize how important quality sights & dots are. Vortex, Leopold, Nikon are all good brands and for your purposes will excel. Best of luck on the upcoming season with your son!
