Worth it.... - Aero Precision AR15 16in 5.56 Complete Upper Receiver with Flash Hider with Pinned FSB, M4 Handguard

I had been interested in building one of the aero precision ar milspec versions so I ordered the upper with the bcg and charging handle...got it for just over $300 by watching for sales and deals. It came pretty fast and I paired it with almost all aero precision parts and lower. I took to the range and it kept a pretty tight shot group....as good as any military version I've used over the last 30 plus years....I used a lot of them...I am very happy with this upper especially with the reliability. If you were married to one of these most of your life like I was this will make you happy.
