Confirmed, my Core15 basic gas, is commercial tube.

Awesome guys. Just to clarify, the scope is a 1.5 MOA dot, not a 5.
Sorry for the late review. Life's been busy. None the less, here's some results from the gas (DI) upper. I should be back to the range shortly to play around with some more reloads. I'm not really liking the results with some of the factory ammo, especially the cheaper stuff, but some of the reloads look quite promising. Was slightly breezy the day I shot these.

All these grouped were shot with a Vortex Diamondback 4-12x40 scope.
Post #52 were all those groups shot with the piston upper? Theres a few good groups in there.
Yes. All previous posts were with the piston upper.

I know I'm bringing this one back from the dead. Do you still own the rifle? Did you keep the piston upper or did you ever get the rifle entirely replaced as promised?
Prepare for the worst and hope for the best.

I have a core15, gas upper. Love this rifle. Great quality so far. I have had mine for a couple years. My wife loves it.

I kept the piston upper. Had a problem where the piston bent once, but was replaced with no issues. This is my primary 3 gun rifle, and other than the bent piston, has worked flawlessly. Only mods to the rifle are a Gisselle sde trigger, spikes tactical buffer, and a michelak brake. Otherwise it's as delivered. I've taken the scope off and shoot open. Zero on the supplied magpul sights hasn't changed a bit. I won't be doing any more load testing until I get a better scope. I feel the scope I was using is limiting the accuracy of this rifle.
