I'm having problem with my new AR15. Most of the time it will not fully load a cartridge.
If I fire the rifle with 1 cartridge in the mag it does engage the bolt stop, so short stroking isn't a problem.
My problem is that when the Bolt Carrier Group charges the next round it will leave it half-way out of the chamber and the BCG will not go to Full Battery. In other words ... if I look at the ejection port I see a cartridge that is half way out, and the BCG is there in the half position.
Here is what it is doing to my brass. Any suggestions will be appreciated.
