If I have a PSA complete lower that I purchased, would this be all I need to an complete an AR? I've never built our built one.

I can buy this upper right? I’m 19 years old.
Dawson on Jul 7, 2018

Works fine
Did everything I expected of it. I haven't shot it very much yet so I can't give a lot of technical detail, but I'm happy with it. Good trade-off between the price and the features.

PSA Complete upper assembly
Let me start by stating this isn't my first purchase from PSA. I grabbed a Century VZ 2008 some years back when they had them and I was greatly impressed. My new AR upper assembly arrived on time and well packaged. I have not had time to range test but the fit and finish is excellent and it coupled right up to a new Ruger 556 Elite lower I had sourced for this build. PSA definitely get 5 stars and a big thumbs up from me.

Awesome fit and finish!
Needed 3 uppers to complete first build with my boys. These fit perfectly and were a great deal. Can't wait to get to the range and see them in action.

Great Upper
Fit and finish are perfect. Feels solid. Shoots smooth. No malfunctions with first 100 rounds ( I haven't shot it again, but I am looking forward to the next time ). I would buy it again for sure.
