Now that AR parts are somewhat more available I am able to replace some stock stocks (haha). The M4 stocks work, but there are definitely better in terms of durability (or so I think) and especially storage. For my 6.8 I even would like to replace an M4 stock with a full A2.

So who builds the "best" one? Everyone has their opinion and favorite brand. Ever want to drop-test all of them and see which comes out ahead?

Well, GearScout.com did and it makes for a good read: http://blogs.militarytimes.com/gearscout/2012/02/01/buttstock-bashfest-gearscout-finds-out-just-how-far-tough-talk-goes/

The good news? It seems like they all did comparably. The bad news? The all broke.
Oh well, I still need some place to put extra batteries.
