While barrels and optics get the glory, the \u003cstrong\u003efire control group\u003c\/strong\u003e is the engine that translates your intent into action. We provide the internal components that turn a standard rifle into a precision instrument.

The trigger is just the lever your finger touches. The fire control group (FCG) is the complete system responsible for the ignition sequence of the firearm.\u003c\/p\u003e\n\u003cp\u003eIn the standard AR-15 fire control group, this system includes four critical components that must work in perfect harmony:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Trigger:\u003c\/strong\u003e The user interface that releases the sear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Hammer:\u003c\/strong\u003e A kinetic energy storage device.

Understanding what is included in fire control group kits is vital for builders. Some kits are simple \"lower parts kits\" with standard mil-spec components, while others are high-performance tuned systems designed to change the physics of how your gun shoots.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eThe Mechanics of \"Feel\": Why Upgrade?\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe standard AR FCG found in most off-the-shelf rifles is built for low cost, not high performance. These military-specification (mil-spec) triggers often feel \"gritty.\" This grit comes from rough metal surfaces rubbing against each other before the hammer releases. This friction causes you to apply more force, which can pull your sights off target just as the gun fires.\u003c\/p\u003e\n\u003cp\u003eUpgrading to a match-grade firing control group changes this experience entirely.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe Break:\u003c\/strong\u003e A high-quality trigger breaks like a \"glass rod.\" There is no grinding or movement; just pressure and a sudden, crisp release.

Enhanced groups feature a \"short reset.\" You will feel and hear a distinct click sooner, allowing you to fire follow-up shots much faster.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Time:\u003c\/strong\u003e This is the time it takes for the hammer to hit the firing pin after the trigger breaks.

Introducing the CMC 10\/22 Trigger. The CMC 10\/22 trigger is a drop in, self-contained trigger pack that is easy to install, with a factory pre-set, non-adjustable 3.5lb trigger pull weight. It features a new textured bolt hold-open button with auto drop function instead of the traditional lever commonly found the Ruger 10\/22 rifles. It also features a fully ambidextrous textured magazine release paddle for quicker magazine changes. The CMC 10\/22 Trigger utilizes the most advanced manufacturing and quality control techniques. CMC's critical sear engagement surfaces have a proprietary machining process that renders superior surface finish and dimensional control. As compared to their competition, the techniques used to establish a 1-2 RMS surface finish as opposed to EDMing which leaves a pitty 32 RMS, compared to a mirror which is 0 RMS. It is CNC-machined from a single piece of aluminum billet. The use of aluminum and precision CNC machining allows for greater internal clearance. This clearance reduces drag and friction and provides a smoother felt pull. The trigger is extremely well made, much more durable than the standard stock Ruger trigger and includes CMC's Satisfaction Guarantee and Lifetime Warranty.\u003c\/p\u003e\n\n\u003cp\u003eKEY FEATURES:\u003cbr\u003e\nMade from 8620 Alloy Steel and S7 Tool Steel with machined tolerances of +\/– .001″ | Totally self-contained one-piece assembly | Single stage, factory pre-set, non-adjustable 3.5lb Pull Weight | Mag Tension Bar | Enhanced Bolt Hold Open Button | Auto-Drop Bolt Hold Open | Captured Ejector | Fully ambidextrous magazine release lever and textured controls | Ultra-crisp trigger with no creep prior to hammer release | Glass-smooth break with grittiness | Minimal lock time is designed into the assembly using controlled hammer weight and balance activated by a rocket wire hammer spring, assuring repeatable function with either commercial or military grade ammunition | Positive trigger reset allows a quick follow up shot on target | and assembled, and hand tested | Easy to install\u003c\/p\u003e","brand":"WH3","offers":[{"title":"Black \/ Matte","offer_id":47705426165974,"sku":"64503","price":225.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/0635\/5980\/files\/CMC64503_1.jpg?v=1767701510"},{"product_id":"cmc-triggers-ar-15-lower-receiver-parts-kit-with-3-5lb-curved-trigger-black","title":"CMC Triggers AR-15 Lower Receiver Parts Kit with 3.5lb Curved Trigger -  Black","description":"\u003cp\u003eEnhanced with a 3.5lb Single Stage Curved Trigger, this kit is a great addition to your AR15 build.
