The JARD Desert Tech MDR Sear Assembly delivers a smooth crisp trigger pull to the Micro Dynamic Rifle. In addition, it reduces the trigger pull weight from approximately 5 lbs. (factory pull weight) to 2.5 - 3.5 lbs. depending on adjustment which is covered in detail in the owners manual. Drop in installation is quick and simple (see video below) so you can get straight to enjoying superior trigger performance.
