I built (assembled) a .308 for a buddy of mine. The rifle set in his safe for 8-10 months before deciding to take it to the range. I went with him so we could run it and site in the optics that he bought for it. So, first issue is that it continually would not eject the spent case and the following round would jam in the middle of the ejection port. This happened numerous times and we decided to call it a day. I was thinking that since it had set so long unfired that it probably just needed a deep cleaning and lube.
I broke the rifle completely down. Tore down the BCG and cleaned it with a soft wire wheel on a Dremel tool. oiled everything up extremely well then checked the gas system. The gas system is correct for the rifle and aligned properly. Head back to the range a few days later and it now charges better and ejects the spent case flawlessly but does not chamber the next round. Its as if the gun is cycling too quickly.
Has anyone dealt with an issue like this? I'm thinking that maybe the springs in the Magpul mags are not stiff enough to push the next round up in time, maybe the buffer is not correctly weighted? Any ideas?
