Southsider's Review of Stern Defense AR-15 6 inch Assembled 9mm Upper Receiver w/ 8 inch MLOK Rail

Bought this upper to mate with a dedicated Glock mag 80% lower. I have feed problems with the bullet jamming up on the barrel with most hollow point ammo. Tried changing mag manufacturer from magpul to Glock OEM with no improvement.
