Looks good, but looks don't get the job done - NcSTAR AR15 Armorer's Wrench Gen2

Many of the features of this tool will work well. It is the Barrel Nut end that is lacking. The tool is made out of less than optimum metal. In the hand it feels more like pot metal than a steel tool. I used the Barrel Nut end once and it bent with only moderate force being applied. There are better tools available. I would suggest that if the description doesn't include what the tool is made from, then it might be best to avoid the tool. I'll chalk it up as 25 bucks worth of experience.
