Yeah, sure, give into the peer presure and don't get one.
I've ran one on my rifle for the better part of a year now. I went with the magpul one and found that it has helped me with malfunction drills (locking back without having to change everything up) in the begining, I did have a problem like DStevenson, where I would get going too fast and send the bolt home too soon. After forcing myself to slow down for a couple classes and focus on changing my reloading process I havn't had the problem since. Like anything else, if you want to try one, train with it long before you run it in real life.
A valid arguement PsychoFish.... It without question helps with malfunctions as its now much easier to lock that bolt back.
I'll run it some more with and without gloves and give it another shot.
