Gee I guess it isn’t just DPMS that have problems!!!
Maybe he needs to recut his chamber!!!
To be honest, I don’t come to this board to see ar15.com threads.
The AR wasn’t meant to chamber non-brass ammunition. It wasn’t even made to chamber bad ammunition. It was meant to be used with high quality ammo.
Putting cheap ammo from a former bloc country in your AR is like putting diesel in a Honda Civic.
Also, ARFCOM isn’t a good source of info.
