I enjoyed all the products so far. I plan to purchase more products in the future, keep up the good work!
I used this tool to build a Nefarious Arms A3 IAR barrel on an MR556 upper, and it was absolutely perfect for the job. It easily held under the required torque specs with zero barrel shift. More importantly, it eliminated any worry about shearing off the index pin, ensuring near-perfect timing after installation.Before this, I attempted to use a Midwest Industries Reaction Rod but found way too much play. The MR556 platform demands tight tolerances, and a generic reaction rod simply doesn't offer the precision needed. Because this tool is made specifically for these barrels, the fit is exact. If you are doing an MR556 build, this is the tool you need.
