I'm having trouble with my AR15. It's a Remington predator about 10 shots at the 100 or more the pin hits the primer but it doesn't go off it's like a miss fire but if you put it back in it will fire it. I've ripped apart and cleaned it twice now. I'm just wondering what it could be I think that's something do with the trigger? Is this common I don't know I just got it I don't know much about it. Where I got it from said that there's a 6 to 8 weeks. Waiting time frame and it was used and they don't know it's under warranty. Can anyone help thanks

Well, first question would be what ammunition? Norinco ammo is notorious for having hard primers, as is other "military" surplus ammunition. They have harder primers to reduce the chance of a slam fire when a cartridge is chambered and the firing pin bounces off of it due to inertia. It's a very slim chance, but it adds up if you're loading and unloading the same cartridge repeatedly.
The next thing that comes to mind is the firing pin. When you say you cleaned the gun, how in-depth did you go? Did you remove the bolt and firing pin and make sure they are cleaned? If you did that, it's important that excess lube does not get on the firing pin. If lube or grease builds up in there it can turn your firing pin into a hydraulic ram and cause problems as it tries to force the oil out.
Your random fact of the day is that excess lube turning into a hydraulic ram is also why you want to avoid putting too much lube on your cases or their shoulders when reloading brass. The lube gets trapped in there, and since the brass case is weaker than the steel or carbide sizing die the brass gets dented. I don't like the summer heat, I'm rambling.

First thing, check your ammo like Stevenbot said. Cheaper ammunition (and various reload ammo) tend to have problems like this arise with misfires etc. (never heard of your situation myself but could still be related.) But basically change your ammo first everytime when testing. Had a .22 Ruger today that wouldnt even chamber properly let alone cycle. Popped some better ammo in it and bam, fires like a corporate merger.
To my basic knowledge thats all I can suggest. Things like this do happen and its normally the ammunition you're shooting. So test that first, THEN take your firearm apart if needed. Might save you a lot of time the next time around.
