So I was at sportsman's warehouse killing some time the other day and came across the Magpul stuff and the MOE hand guard that was in a different looking box and said it was made for both DI and piston guns. The Magpul website doesn't have any mention of this, in fact, it says on their website that their hand guard is NOT compatible with any piston systems. What's up with that?? Does Magpul have an MOE Hand Guard MKII and they don't want to advertise for it??
