I know that this is already an old story having been online in January of this year, but many of us may have missed this article at Military Times Gear Scout Blog where they subjected 13 buttstock to some tests. Will airsoft versions of these withstand the test? That will be nice to know of, and if you send us a budget, we'll do it for you. But for now, this is interesting reading for those who are still curious about this test.

"What makes a good collapsable stock? One that’s rigid, offers a good cheekweld surface, has a solid, simple locking mechanism and the ability to hold up to bumps and drops inherent to battlefield conditions.

Solid lockup can be had across the board, but look for a secondary friction lock if you get annoyed by rattling. Though, that rattle also equates to a tiny amount of play in the system and could have an effect on the rifles accuracy when taken to extremes.

Sling attachment points should suit your carry and shooting style. Tube tops should be smooth and fit your face. That goes for the hairy among you, interruptions in the cheekweld surface will pull beard hair and cause a loss of concentration. Of course, weight and size are constant considerations, and modularity fits here, too. Some stocks have removable storage that can be pulled to save ounces if not needed."
