thanks A lot everyone. i've been playing since 96' and never dealt with mags. i feel like a noob again calling field owners asking why my Bass Eagle Poison
There isn't any safety issue in sanding/filing down a burr here. A small fine tooth round file or some fairly fine sandpaper wrapped around a dowel/pencil/something
Sand it down a little. No big deal. Just make sure its smooth when your done. Or leave it and let the bolt buff it if it isn't breaking paintballs.
