    For muzzle devices, I use barrel vice blocks. For barrel nut or handguard install/removal, I use the reaction rod.

    No issues with either. Before buying the barrel vice blocks, I used the RR on more than one occasion, and had no issues. As IG said above, you have to be smarter than the equipment you are using.

    This barrel vice block from brownells has blue rubber that leaves little to no marring on the barrel.

    I've removed and tightened 1000s of bbl nuts using a Geissele reaction rod and haven't sheared an index pin but also don't torque past 80ft lbs. I prefer not torquing bbl nuts past 50-55ft lbs when possible.

    I have used those as well, and in many cases the barrel rotates or twists. It also doesn't work with all profiles from what I have seen.

    The problem with barrel vice blocks is they aren't useable with a lot of configurations, like extended handguards or my 11.5" with 10.5" handguard.
