What are the odd's of this happening
A friend was shooting his AR, no issues, all of a sudden the rifle stopped cycling, he could manually cycle the bolt to load a round out of the mag and it would fire, just wouldn't cycle, he repeated this a few times then gave up.
Took the rifle to bits, had a good look, couldn't see anything obvious, stripped the bolt/carrier group, still couldn't see anything, after much discussion and "expert analysis" he blew down through the carrier key to make sure nothing was untoward, low and behold there was a primer rammed right down the end of the carrier key effectively blocking the gas system off, checked his spent brass from the day and yep there was a case with a missing primer.
Came to the conclusion that the primer blew out, tumbled around and got caught in between the gas tube and the carrier key while the rifle was cycling that round and got rammed down the key.
What do you reckon the chances of that happening twice are?:eek:
