Better than oe - V Seven Titanium Kmr Barrel Nut

Bought one of these to have an extra during a barrel swap. I've installed several MCMR rails. Factory barrely nut grooves for the installation wrench are so soft and always deform during the torque/setting procedure and I end up having to file down the edges so the rail will slide over the barrel nut easier - enter the V7 titanium nut. Weighs nothing, not a single deformation during the install procedure and has a nice thermal fit with the handguard just like factory. Only con is the price - but hey you only live once.
