The upper on top is a radical firearms. The upper on the bottom is a PSA. Both have rifle length gas systems, 15" M LOK handguards, and 18" 416R SS barrels chambered in .223 wylde. Less than 100 rounds fired through each. Government profile for both barrels. The PSA M LOK handguard has a QD sling socket built into it, and is a little lighter. The PSA has a standard A2 birdcage and forward assist. The RF has their own compensator/flash hider that is cool and interesting, as well as their own forward assist. I'm selling these to fund a high end AR build. I used to have a fascination with 18" rifle length guns, but not anymore. Both of these uppers have ran flawlessly for me.
If you want me to ship these, we can work something out.
