I purchased a used AR and installed the used upper on a new lower and have been having some issues. The gun jams about every 5 rounds and the ammo cases seem to be very dirty with fouling. I also noticed the gun seems very loud compared to other AR15's. I'm assuming there is so much fouling that things just aren't functioning properly in the upper. The gun was cleaning prior to going shooting so I know it wasn't old fouling left behind.
Thanks
