It's a CORE rifle. All stock except a JT red trigger spring kit and a 3 chamber brake

What type of mags, have you tried more than one?

Yes. Multiple. C product that came with it. Multiple BCM D&H 30 rd mags and a PMag

I'm looking for the rest of the specs now.

Try a different lower.

Also, try to get a picture of the real malfunction next time it happens. Looks like it may be a bolt override.

What buffer does it have?

[cdclpc]

Bcg

CORE15 Mil-Spec Carpenter 158 Steel Bolt, M16 Chrome Lined 8620 Steel Carrier, Mil-Spec Staked Gas Key, Tool Steel Extractor, Shot Peened

Upper

CORE15 Mil-Spec Forged 7075-T6 M-4 Upper Receiver, Type III Class II Hardcoat anodized finish, M4 Feed Ramps, (1913 Picatinny rail flat top) with dry lube internal finish and laser engraved T-markings

Barrel

CORE1516” Mid-length Profile 1:7 Twist, 4150 Black Nitride Finish

Straight off CORE's website. No buffer weights though. I suspect standard carbine buffer.

Can you describe "bolt over ride"? Sounds like this looks.

Does the bolt lock back on the last round?

First thing I'd do is give it a good cleaning to get that lube off the feed ramp.

You mentioned running it dry,I wouldn't advise that and it will cause problems regardless of what the manufacture says.

Without seeing the FTF assuming it's not a mag issue I would look into the gas stystem, does it feel like it has enough gas to feed the next round or does it feel like it's short stroking? Does the gas block look like its lined up correctly or anything loose?

It always locks back last round. I'm cleaning as we speak. My brother, who is LEO has recommended some lube to use in the future.

I thought that it's short stroking and initially mentioned that to my brother but the brass is ejecting kinda forward.
