Rails Kits and Locking Blocks for 3D Printed Glocks (4 Best Companies)

We reviewed the best companies to help finish your next 3D printed Glock

You know, the ability to 3D print your own Glock is a really cool part of where we’re at with our technological capabilities. Finding quality parts is important, too, especially for the rails & locking blocks for 3D printed Glocks.

The rails and locking blocks are important because they ensure your gun functions as it should, preventing any malfunctions or injuries. They are also made out of metal rather than 3D printing filament, so you will need to get them from somewhere else.
