Aero precision assembled upper

Tried out the new upper yesterday in .224 Valkyrie and it works perfect.

Quick quality

Had some spare parts but needed an upper receiver to make a complete 5.56 upper. This fit the bill so to speak. Quality seems really good. Didn’t appear to need lapping. Went together with barrel and nut with proper torque without issue. Very light so if that’s important to you it will do nicely. Arrived quickly which is difficult in my neck of the woods.

Good Product Good Company

As easy as it is to assemble an upper receiver with a pin punch, it’s just easier to get one already assembled and be done with it. With what you save doing it yourself It’s easier buying it assembled unless you just have and upper parts kit laying around you need to get rid of.

Can never go wrong W/ AREO

As always, it was a perfect fit. This time on a old Anderson lower I had lying around. In my opinion AREO has some of the best upper & lower receivers on the market.

Aero precision does it again!

The rifle I used this on has another brand of lower receiver (Anderson) and when you mix and match, fit and finish can become a nightmare. With this upper finish was dead on, and the fit is very very tight. Good job Aero and great job from AR15DISCOUNTS. THANK YOU ALL
