I just finished a DPMS 308 build and am having problems with chambering. I can sometimes shoot up to 10 rounds without issues. Others it will be 5-6 chambering issues out of ten. Tried 3-4 different types of ammo, grian weight, and brands. Different mags, new and used. The gun is built with good brands and everything is installed correctly. I'm thinking the issue is related to the m4 feedramps. The upper is Aero, with a Fulton barrel. Both are m4 but the aero upper has more shallow cut. There are brass shavings present and scratches on the bullet itself.
