Powderman is dead on. That buffer is too heavy for whatever gas system that WOA is using. Put an H2 buffer in and you probably won't have any more problems. The reason they put a heavier buffer in the A5 extension is because they are using a rifle length spring and there is less tension at rest in the longer extension than there is with a carbine length spring in the carbine extension.

Other possibilities are bad gas rings, loose gas key, or partially blocked port. Being the carrier is a BCM, I'd highly doubt the key isn't done right or the gas rings are bad being new.

You don't have to have an AR sloppy wet to have one run good, that is complete crap.
