For ar repair and building, you'll need little else. - Real Avid AR-15 Armorers Master Kit Pro

I've had my eye on this Armor's tool kit for quite some time. There can be no doubt that this tool kit has just about everything you'll need for AR repair and building whether or not you'll be doing DIY work for setting up shop for yourself for full time gun smithing or as a side gig.
The completeness and quality of each component is very good and Real Avid has seems to have put a great of thought into all their products and the Armorers Master Kit pro is no exception.
Now there are some tools are AR specific but a good many of them can be used on a lot firearms including shotguns, rifles and pistols.
Because there are so many pieces in this kit, it is best to do an inventory of everything in this kit when you get it.
I noticed that the AR Pivot Lock and the AR15 Pivot Pin Tool was missing from the kit. I contacted Real Avid and they sent me replacements within a week.
To be sure, if you plan to work on a variety of firearms, you'll need platform-specific tools that you can purchase from Optics Planet.
And this kit forms a solid core for everything you need to do.
