These are the best of the best.
Don't be concerned about ordering aero products, they are as good as it gets as far as quality fit and finish are concerned.

Great upper !

Aero makes great products. And for the price you can't go wrong. My only complaint is that the upper and lower do not fit well together being cerakoted. I has to sand some off of both upper and lower for the pins to line up. Very very tight fit. Still no big deal. Just be aware of the tighter fit due to the extra coating.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
