This pin kit is designed to permanently attach the upper and lower receivers together on AR pattern rifles. POF-USA developed this kit to ensure that the upper and lower can never be completely separated from one another.
This pin keeps the upper and lower together, while acting as a hinge to open the action. We offer two different sizes. One for our AR-15 type firearms and one that fits all P-308 receivers, Rogue LMR receivers, Revolution CMR receivers, Phoenix PSG receivers, and P-SG 22 receivers.
An AR-style pivot pin is the front attachment point for the upper and lower receiver of your firearm. The front pivot pin acts as a hinge point between upper and lower receivers. It allows for easy disassembly and reassembly during regular maintenance or cleaning.
