Doesn't come with everything - Real Avid AR15 Armorer's Master Kit

This is a pretty good kit. Unfortunately the included hammer only has provisions for barrel nuts that have a delta ring or barrel nuts with 6 pins with 2 pins side by side. Unfortunately, it doesn't include a 3 pin barrel nut. This kit worked great for building the lower, but once I got the upper on the vice block I was disappointed to find out this didn't have the wrench in it I needed. For other people's reference it was a barrel nut for a SPIKES TACTICAL SAR3 HANDRAIL. It's a 3 pin wrench. The torque wrench is of a beam design which is bare bones basic and for the price a click type torque wrench should have been included.
