AR15 Buffer Retainer Pin Ten-Pack for Builds and Repairs
The buffer retainer pin is a small component with an outsized job: it holds the buffer and spring in place within the lower receiver, keeping your buffer system seated where it belongs. Because it sits under spring tension, this part can launch and disappear during disassembly or a build, turning a quick job into a stalled range day. This ten-pack of tempered steel pins, made in the USA, keeps spares on hand for AR15 builds, repairs, and routine maintenance.
Buyers assembling or servicing AR-pattern lowers often keep extras nearby, since a single missing pin can prevent reassembly. Pair these with the matching buffer retainer spring ten-pack and an AR15 carbine buffer when restocking your build bench.
Verify fitment with your lower receiver and buffer system before installation, and use proper tools to manage spring tension. Builders restocking small parts may also keep the pivot and takedown pin springs within reach for the same job.

Yes, the product is listed with mil-spec dimensions and built for AR15 / AR-pattern lowers. As always, verify fitment with your specific lower receiver and buffer system before installation to confirm compatibility with your build.
The retainer pin works together with a spring under the buffer tube. Many builders restock both at once, so you can pair these with the matching buffer retainer spring ten-pack when restocking your build bench.
Verify fitment with your lower receiver and buffer system before installation, and use proper tools to manage spring tension since the pin sits under tension and can launch. Keeping spares nearby, along with the pivot and takedown pin springs, helps avoid a stalled build.
