Blue is correct, the heavier buffer and longer spring of an A2 stock are very forgiving. Not much needs to be done nor can be done.
All the problems associated with the carbine gas are less of a problem with a fixed stock. But I do hear the "sproing" noise on a fixed stock. Unlike a Rost who zones out while shooting, I lack any Zen shooting tendencies and sort of feel the whole firing process, including when my bolt locks back on an empty chamber.
