Hello,
I am a newbie to the 9mm carbine, and am having trouble with the build hope I can get some help here?
I have a DDLE 9mm lower and CBC upper it came with the bolt they say it’s a Glock bolt and that is what I want. But it seems like the ejector is too tall, I did not install this ejector it came installed with the lower.
My question is do I need a different bolt and which one?
Thank U

Does the gun cycle and fire without issues ??
Because that is where you should start with a diagnoses of a gun.
