Pros:
1. They're good at keeping your hands off the hot barrel, although not perfect since they leave the very top open.
Cons:
1. They're rude expensive. I get it, it costs money to machine them. But damn that's a lot of money compared to a set of flight gloves.
2. They're heavy, and that weight is all out towards the muzzle.
3. You have to really keep on top of the magazine extension/cover (depending on generation of 1301), because if that gets loose, it's the only thing holding the handguard tight against the receiver and I've seen several of these come loose and break the little tabs at the receiver end of the part during classes.
