Was happy with everything but the "Combo tool" (barrel wrench).
I ended up shearing off almost all the teeth on the barrel nut before I finally ended up breaking the thing loose. A couple per try. Reading the reviews at Midway, I'm not the only one. My opinion, but I think the Wheeler wrench didn't have enough engagement to do the job properly. Two pins, IIRC. It took a SERIOUS amount of force to break loose. I'm a big boy, used all 250 lbs plus a breaker bar, plus beating with a rubber mallet, and it still didn't want to turn loose.
My experience with the Wheeler wrenches has been similar, they are soft metal, poor fitting, and not serious tools for barrel work. I have a GI wrench, and a couple types of commercial barrel nut heads that work better than the Wheeler.
I recommend a barrel wrench with a barrel nut head that engages the majority of the teeth on the nut, the tool heads with the three pins will often sheer the barrel nut teeth off. Barrel nuts are sometimes soft metal as well, and the pins won't hold on them enough to turn the nut.
IIRC, the three pins are supposed to be used only for the DPMS style round barrel nuts with the circle of gas tube holes in the face of the nut.
I think the Magpul tool is good quality, but I have the tools it offers already, or I'd buy one.
Like TWR said, you start collecting tools for different installs...
