A customer requested that we design a spacer for AR reaction blocks that banks against the block on one end and the FCD castle nut socket on the other to keep it in place during torquing.
It is .806" thick. Let us know HERE if you need a different custom one.
.801"and 3.675" variants are available.in the drop-down list.
.801" was requested by a customer for a specific castle nut wrench.
3.675" was requested by a customer for the FCD Castle Nut Socket and the blue VISM Lower Receiver Block. Note the price difference for this variant.
It's made from carbon fiber reinforced high temperature nylon and provides a low-friction, wear-resistant surface.
