Enhance the fit and function of your AR-15 small-frame (.223) receiver with the MicroFit Front Pivot Pin. This precision-engineered pin is compatible with all Mil-spec small-frame receiver sets, ensuring a tailored fit for your build. Whether you're eliminating receiver slack or facilitating smoother takedown of tightly fitted components, MicroFit offers both oversized and undersized options to suit your needs.

Mil-spec AR-15 pins are approximately .248 inches in diameter. MicroFit pins deviate slightly (about ±.001 inches) from this baseline, allowing you to fine-tune the interface between upper and lower receivers. Use a standard takedown or .248 gauge pin to evaluate your current setup before selecting your MicroFit pin size.
