.300 BLK weird ejection question

[tcecil88]

I have a question for the .300 BLK guys in the house. I have 1 that is ejecting weird. It ejects to 3:00 but only about 6 inches or so, with the last round facing backwards in the receiver with the bolt held open. It has a 6 inch Ballistic Advantage Modern series barrel with pistol gas, Black Rain Tactical adjustable gas block and a GunTec mil-spec bolt. I turned up the gas to try to give it some more positive ejection with no change. Any help would be appreciated.

I'm not an expert , not even close so hopefully one chimes in but since you said adding gas made no change at all I would be looking at my bolts components ...ejector , extractor, associated springs

Know enough about the AR to be dangerous and have never fooled with 300BO but sounds like a weak ejector spring to me.

My research showed the ejector the most likely culprit as well. Thanks for the responses.

Had a friends 300 do exactly what you describe. It was indeed a weak ejector spring. PSA Premium BCG

I ordered Wilson Combat Chrome Silicon Ejector and extractor springs as well as their one piece gas ring to try out. I will post the results when I am able to shoot it again.

**Update**
The new Wilson Combat Springs fixed the issue and the one piece gas ring seems to work well. Fired 40 rounds without issue and all rounds cleared the weapon as they should. Most landed 3 or 4 feet away. Highly recommend the Wilson Combat Springs.

Late to the thread here.

Something I have run into more than once. Having a spare BCG or even another rifle to swap BCG's is a very helpful diagnostic tool, on top of being a smart prepper sort of thing to do.

Prompted me to check the safe. Sure as the world, a NIP BCM BCG laying in there. On duty for problem rifle diagnosis or the next build.

Yeah, AIM Surplus had Blem BCG's in the showroom for $50 the other day. I may go get one to put away. But my spare parts usually evolve into another gun.

They tend to do that. I'm guilty of that also.
