Excellent product - Real Avid AR15 Armorer's Master Kit

I've used this kit for 3 AR builds so far and it is excellent. The pivot pin tool makes that process simple. Excellent quality and well organized. The punches are good quality and the proper size for just about everything. One punch is milled down on the side to give you proper clearance to install the bolt catch without hammering close to your lower. The block is useful for many functions, but I've found it works best to install the trigger guard first.
