Palmetto State Armory
Overview
The PSA PA10 Pivot Pin is a steel component designed to secure the upper and lower receivers of your AR-15 build, allowing for smooth operation during assembly and disassembly. This pivot pin is essential for maintaining stability in the firearm's function, as it ensures proper alignment of the upper and lower halves. It's commonly found in builds utilizing a pistol gas system chambered in 5.56 NATO, making it a reliable choice for compact and tactical configurations.
Prices checked
Builders have been adding the PSA PA10 Pivot Pin to their builds on GunPartPicker since February 2026. All time, it ranks #101 of the 149 takedown pins builders have added.
Availability is good: it was in stock at one retailer or another nearly every day in October 2026, and today the one retailer we track has it in stock. Prices barely moved in October 2026, holding around $14.99, so there haven't been real sales lately. Buying today, the lowest price is $14.99 at Palmetto State Armory, which matches the best price we saw in October.
