Dropping a full mag on a GBBR can be done, but is not recommanded, you'd better shot in bursts of 3-4 bb as it reduces cool-down. If you play semi-auto it's even better. Also check that the bolt is well lubed.
that is what i figured when i first used it. thanks for the info, any good links to information or videos to the lubing of your gbbrs?
as for the grease, i will search it up
