The KNS Enhanced AK Trigger and Hammer Pins are better in both material and finish compared to standard ComBloc AK fire control group pins for your Kalashnikov-style firearm. Their Enhanced AK Trigger & Hammer Pins feature a Black Nitride finish for a smoother, corrosion-resistant surface and are machined from high-quality alloy steel. Whether you're building your AK from scratch or upgrading your trigger, KNS's pins offer a simple and sleek upgrade that will make your trigger pull smoother. They fit standard AK receivers as well as classic Galil models: MAR, ARM, and SAR.
