Schmid SI-FCG-1 Mil-Spec Fire Control Group

The Schmid SI-FCG-1 Mil-Spec Fire Control Group is a reliable and cost-effective drop-in trigger system for AR-15 platforms. Manufactured to strict military specifications, this complete fire control group includes the trigger, hammer, disconnector, and all associated pins and springs needed to complete your lower receiver. It is ideal for builders and shooters who want the rugged dependability of a traditional mil-spec trigger assembly at an affordable price point.

This Schmid fire control group features standard single-stage geometry, offering a predictable pull with a clean break and strong reset. With a pull weight of approximately 6lb – 6.5lb, the SI-FCG-1 is well-suited for duty rifles, training builds, and general-purpose carbines. It ensures consistent performance with no frills—trusted by OEM manufacturers and gunsmiths across the industry for its proven reliability and straightforward installation.

Precision machined from heat-treated steel components, this AR-15 trigger group is designed to withstand the stresses of repeated firing while maintaining proper sear engagement and long-term durability. The phosphate coating helps resist corrosion and wear, particularly in high-friction areas like the hammer and sear surfaces. Its mil-spec design makes it compatible with all standard AR-15 lowers that accept .154″ small pins.

Installation is quick and simple, requiring no tuning or adjustments. Once installed, the SI-FCG-1 provides a familiar trigger feel that is easy to control, especially for users trained on standard military rifles. It delivers strong hammer energy to ignite even hard primers, and its robust spring tension minimizes the chance of light strikes or failures in adverse conditions.

Whether you’re completing your first lower, restoring a rifle to original military configuration, or building a reliable field-use AR, the Schmid SI-FCG-1 offers consistent mil-spec performance. Known for quality and long-term dependability, Schmid trigger groups are widely used across the firearms industry by manufacturers and builders alike.
