With internal parts EDM cut from A2 tool steel, then heat treated and polished for consistency, these triggers are manufactured with great care and attention to detail in order to provide the end user with a smooth, positive break. Triggers are fully adjustable for both sear engagement and weight. Triggers for use in pre-2006 guns use the factory safety, while those for post-2006 guns (using Remington's X-Mark Pro trigger) include a new right-hand safety and bolt release. Technical InformationImportant: Use existing pins to reinstall the trigger. There are no new pins, nor are they required. Gunsmithing may be required This trigger does not fit the Remington 722.
