Just happened to run across this new AR-15 multi-tool last night and thought I would share it with you guys. This tool is specifically designed for installing buffer tubes/stock kits on your AR. If you’re planning on building an AR anytime soon you will need specific tools to complete the installation of certain parts such as a Castle Nut Wrench to tighten the castle nut, holding the buffer tube firmly in place.
The AR-15 Multi-tool from Motorcity Tactical Works has a Castle Nut Wrench and A2 Buffer Tube Wrench built into one tool. Its made from 1/4 inch 304 Stainless Steel and has an ergonomic hand grip design. It also incorporates a bottle opener/hanger hook on the opposite end.
The price point is what caught my eye. At just $12.99 each it might be a good tool to just have hanging around the shop for when you need it. I would love to see them move the 5/8″ A2 buffer tube wrench cutout to the middle of the tool which would give them room to add a .750 or .825 muzzle brake wrench to the tool. All in all, looks like a decent little tool to have laying around. Check them out at http://motorcity-tactical-works.myshopify.com/products/ar15-multi-tool
