Re: First Firearm Thread.
My first thought was, it was the mags you are using, but PMAGs are the way to go.
Even if it is dirty, i mean really dirty it should fire as long as you keep it lubed.
Sometimes on new ARs the Bolt fits very tight inside the bolt carried because the gas rings are very new and create a great seal. make sure that your bolt has a thin coat of CLP on it. Also make sure the little holes on the gas rings are not all lined up, this could cause you to short stroke. Don't be afraid to throw a little lube on your buffer spring and buffer.
I would not use Motor Oil as a lubricant because it tends to be a bit thicker then firearms lubricants and retains more "Gunk". CLP is an all in one, it cleans, lubricates, and protects well but does none of those great. I recommend using a cleaning product then a lubricant such as slip 2000.
Was the Bolt Carried Group purchased with the upper receiver or did you purchase them separately?
