CMC Triggers – Drop-in Trigger for AR15/AR10 Small Pin Competition – Two-stage – Curved – 2/2 lb – 92502
A cartridge-style drop-in trigger for AR15/AR10 platform carbines in the small pin (0.154″) variant from CMC Triggers. It allows modifying the trigger tongue assembly according to the user’s needs. The trigger tongue has a factory-set trigger pull force at a preset value, which is not subject to modification. After replacing the component, it is worth taking care to properly clean the remaining parts and use lubricants for weapon maintenance.
The entire module is made of machined steel and aluminum alloy. The working elements are additionally hardened to increase their strength. The working surfaces, thanks to high precision machining, have irregularities of 1-2 µin, or 25-50 nanometers, which is similar to the surface of a mirror. This model uses a two-stage trigger type with a curved tongue and tension and a breakthrough of 2 lb, which translates to about 0.9 kilograms.
The 0.154″ pin diameter means that it fits all AR15/AR10 rifles except for those made by Colt from 1991 to 2009. The two-stage trigger is characterized by a staged path, where you first have to overcome the initial pull to then tighten the tongue to the end. Such a solution will work well on weapons adapted to firing methodical and precise shots.
Warning:
- The manufacturer emphasizes the construction of the trigger in the drop-in type, but at the same time it is fully modular, that is, it can be disassembled and assembled with minimal effort, which allows you to seamlessly adjust the module in a situation where the assembly requires a certain order of seating of the components, without alterations and mechanical modifications.
- Do not fire the trigger without a cartridge or a nailer in the chamber, as this risks direct damage to the mechanism.
- Do not fire the trigger mechanism without installing it in the weapon, as this may lead to damage to the mechanism – not subject to claim.
