The LANTAC Ultimate Takedown Pin Set allows the user to install and remove an AR-15 Pivot Pin without the use of a tool. The unique design incorporates a ramped groove that holds the detent in place at the time of installation and another ramp allows access to the retaining slot at 90 degrees to groove. Pins feature aggressively crenulated heads for improved grip. The LANTAC Pin Set is precision machined on Swiss style turning centers and are manufactured from the highest quality materials to the highest standards. They ship complete with LANTAC's 3D printed rear pin removal tool.
The LANTAC Ultimate Takedown Pin Set has a build in safety feature that can be utilized by anyone wanting to make it difficult for an upper receiver to be fitted to a lower receiver. To render a lower receiver inoperable the user can quickly remove the front pivot pin (spring and detent) and insert it through the rear takedown pin hole from the other side of the receiver. Then remove the rear takedown and allow the pivot pin to retain its detent. If the pin is rotated so that the detent registers with the groove on its end then it becomes impossible to remove the pin without removing the castle nut and end plate. It is now impossible to mount an upper receiver group to the lower and have a functioning assembly.
