If you are looking to upgrade your AR-15 or AR-10 with the Delta Velocity Gen2 3MR trigger, you have come to the right place. This detailed guide will walk you through the entire process, from preparing your workspace to fine-tuning your new trigger for optimal performance. Whether you are a seasoned firearm enthusiast or a beginner, following these steps will ensure a smooth and successful installation.
Preparing Your Workspace
Make sure your firearm is unloaded and safe: Safety should always be your top priority when working with firearms. Before you start the installation, double-check that your firearm is unloaded and cleared. Remove the magazine, clear the chamber, and keep the firearm pointed in a safe direction.
Gather necessary tools: To install the Delta Velocity Gen2 3MR trigger, you will need a punch set, hammer, 1/16th inch hex key (included), and a screwdriver or hex key for the handle screw. Having these tools on hand will make the installation process much easier and more efficient.
Removing the Existing Trigger
Separate the upper and lower receivers: Begin by separating the upper and lower receivers of your AR-15 or AR-10. You can typically do this by pushing out the takedown pins and gently pulling the receivers apart.
Remove the trigger and hammer pins: With a punch and hammer, carefully remove the trigger and hammer pins. Take your time to avoid damaging any components.
Loosen or remove the screw holding on the handle: Locate the screw that secures the handle and either loosen or remove it completely. This will give you better access to remove the selector.
Remove the safety selector switch: After the handle screw is loosened or removed, this should allow the removal of the selector as the detent pin is not locking it in anymore.
Carefully remove the existing trigger assembly: Once the pins are removed and selector is out, you can gently lift out the existing trigger assembly. Be mindful of any small springs or parts that may jump out.
Installing the Gen2 3MR Trigger
Place the Gen2 3MR trigger assembly into the lower receiver: Position the new Gen2 3MR trigger assembly in the lower receiver.
Install new selector and paddle(s): Slide the trigger forward to install the new selector and paddles. Ensure everything is properly aligned and secured.
Align the holes in the trigger assembly with the pinholes in the receiver: Make sure the holes in the trigger assembly line up perfectly with the pinholes in the lower receiver.
Insert the trigger and hammer pins: Carefully insert the trigger and hammer pins, ensuring they are fully seated. This step is critical for the proper functioning of the trigger.
Function Check
Ensure the selector moves smoothly: Check that the selector moves smoothly between safe, semi-auto, and the 3rd mode. There should be no resistance or sticking.
Reassemble the upper and lower receivers: Reattach the upper and lower receivers by aligning them and pushing the takedown pins back into place.
Perform a function check: Test the trigger to ensure it operates correctly in all modes. Pull the trigger in each mode to verify smooth and precise action.
Verify the safety selector and trigger reset function properly: Make sure the safety selector works as intended and the trigger resets properly after each pull.
Add one drop of blue Loctite: To prevent the set screw from backing out, add a drop of blue Loctite to the set screw hole once it’s set.
Fine-Tuning (if needed)
Adjust the tension in the spring and plunger assembly: If necessary, adjust the tension in the spring and plunger assembly for optimal reset speed. This step may require some trial and error to achieve the desired performance.
Make any final adjustments: Ensure that the trigger operates smoothly and precisely. Make any final adjustments as needed to fine-tune the trigger’s performance.
Final Inspection
Ensure all components are secure and functioning: Perform a thorough inspection to ensure that all components are secure and functioning as intended.
Perform a final safety check: Before using the firearm, conduct a final safety check. Ensure that the firearm is safe to operate and that all safety mechanisms are working correctly.
