Using these black zinc plated stainless binding barrels and screws on your Urutau lower solves a number of issues:
- Assembly is much easier compared to using M3 screws and stand-offs.
- Stronger than aluminum.
- Prevents the common issue during disassembly where the screw on one side will loosen but the other won't.
- Looks better because it is better.
Set includes four of each. The binding barrel compatible lower STL file can be found HERE.
