Ar15 upper receiver rod - a/k/a reaction rod - OpticsPlanet Exclusive Midwest Industries OPMOD AR15 Upper Receiver Rod - Nickel

I needed a tool to hold uppers when installing barrels. I ordered this one based on the appearance of quality, durability and price. I am very impressed by this heavy-duty reaction rod. The fit and finish are excellent and the ability to stabilize the uppers while working to install a barrel was outstanding. I really like the fact that this tool fits snugly into the charging handle slot. I think this is a much more secure and stable method to secure the upper receiver than a straight, bare bones reaction rod. This was the particular feature that induced me to purchase this part and I'm so glad I did. I think you will be very pleased with this part. It should be in everyone's AR toolbox!
