Last night Dave and I assembled my new upper and today after doing some chores I took it to Boggy Head to try out. I set up a target at 15-20+- yards and 100 yards. On the short target all center of the target. At 100 I was shooting high to the right. Target wasn't set up real well so I didn't make any adjustments on the BUIS but will next time out. I did have an eject issue though. First mag was a 20 round with standard 55gr .223. All 20 shot perfect, fed and ejected fine. Second, 30 rd mag the first 5 or so went fine then they wouldn't eject any longer. My father-in-law shot some so I could observe the ejection and it didn't look like the bolt cycled back at all. Shot kind of like a single shot gun. I even lubed the action up a good bit, just in case. I could eject the empty and chamber the next round and fire it. I looked everything over when we got home but couldn't see anything out of the ordinary, no loose bolts, parts rubbing, etc. Set-up is an Aero-Precision upper with a DPMS M4 barrel and DPMS bolt group. Oh yeah, when I fired the A2 upper last week we had some fail to ejects as well, could it be ammo? Don't remember the brand off the top of my head but rounds are from the same batch.
