Pull delivers a traditional feel with CMCs patented curved trigger bow, offering an exceptionally smooth feel, ultra-clean break, excellent lock time, and a lightning-fast positive reset that makes it stand out among fire control groups. As the original manufacturer of the AR-15/10 drop-in trigger group since 2003, CMC Triggers employs a proprietary machining process that achieves superior surface finish and dimensional control, delivering a 1-2 RMS surface finish compared to competitions EDM finishes that can pit and roughen the engagement surfaces. This kit provides a comprehensive, ready-to-install solution with a complete set of parts designed for reliable operation, including the bolt catch, mag release, safety, take-down detents, and the curved 3.5 lb single-stage trigger itself, all crafted in the United States with a durable black finish. Ideal for shooters seeking a traditional feel combined with modern precision, this receiver kit enhances trigger control, reduces overtravel, and promotes consistent shot placement across AR-15 and AR-10 platforms.
