I am selling a complete AR15 upper in 9mm. I've put several hundred rounds through this using a Palmetto State Glock magazine lower so there is some wear as shown in the pictures.
In all honesty, I found the 9mm AR to be a little frustrating. Experimenting with buffer weights, different magazines, and springs I learned more than I really wanted to. With this upper, factory Glock magazines, and the PSA lower mentioned above I was still seeing 2%-10% failure to feed. Each of these failures would be the same, jamming the cartridge into the flat face of the barrel instead of the barrel itself. This would push the bullet into the case, which was usually good for one laugh. With KCI Glock mags, I would see the same failures increase to about 20%. I switched to a different upper with a Macon Guaranteed to Feed barrel that eliminated the issues I had. The biggest difference seems to be the aggressive feed cone that they use. I have wondered if this upper would work better with a Colt style magazine/upper but haven't pursued that.

4240 AR-15 M4 Charging Handle Mil-Spec Quality

Pricing. I've been pretty honest and the price reflects the issues I have had. The cheapest similar uppers sell for about $150 without the bolt carrier and charging handle. I am including those and will be firm on price. I am interested in trades for brass (10mm, 300bo, .30 carbine). It is easiest for me to meet near Hillsboro, Oregon
