Lantac UPS-S Ultimate Takedown & Pivot Pin Set For AR15 Style 5.56/.223 Rifles - Black
The Lantac UPS-S Ultimate Takedown & Pivot Pin Set are precision machined from 17-4PH stainless steel in H900 condition on swiss style turning centers and then QPQ nitride finished. They ship complete with a 3D printed rear pin removal tool. The Ultimate Pin Set allows the user to install and remove an AR15 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 Patent Pending aggressively crenulated heads for improved grip, this facilitates easier removal of the pin from the receiver. The rear pin features the same retaining slot and ramp, meaning that it can be removed easily by sliding it to a halfway position and then rotating. This causes the takedown detent to ride up the ramp and onto the outer surface of the pin, making removal extremely simple.
The Lantac UPS-S Ultimate Takedown & Pivot Pin Set system has a built 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 pin 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
