Hands down the reaction rod is the best for building and working on uppers. The Magpul BEV block is very nice and is a good tool.GunnyUSMC,
Which is better...
Reaction Rod or
Magpul BEV Block?
I am not going to do a lot of builds (I think...dunno this is a addictive habit) unless someone else is buying the parts. However I can also foresee changing a barrel.
The reason I like the reaction rod better is that you can turn the upper 360 degrees on it.
Botach sells a US made reaction rod for $59
