JARD Ruger® American Rimfire Trigger Installation Guide
Punch (1/16 tip)
Allen wrench (1/8)
Step 1: Verify Firearm is Unloaded
Verify that the magazine has been removed. Work the bolt to the rear position and verify that the chamber is empty.
Step 2: Remove Action From the Stock
First, remove bolt by compressing the bolt catch button on the left side of the receiver while working the bolt back.
Next, locate the allen screws on the underside of the stock and remove with 1/8 allen wrench. Set aside bolt, stock, and allen screws for later reassembly.
Step 3: Remove Trigger Assembly From Receiver
Remove pins with 1/16 punch and hammer to detach factory trigger assembly from the receiver.
*Note: When removing the trigger assembly from the receiver, use caution - guide block (pictured next to loose pins in second image) will become loose. This is a necessary component in installing your JARD trigger.
Set aside pins for later reassembly and transfer guide block to JARD trigger assembly (pictured below).
Step 4: Install JARD Trigger Assembly
Align JARD trigger assembly with receiver and carefully start pins by tapping them with a hammer. Finish installing the pins with 1/16 punch and hammer until pins protrude slightly on opposite side of receiver.
2. Align receiver and JARD trigger assembly with stock and reinstall allen screws with 1/8 allen wrench.
Step 5: Reinstall Bolt and Perform Function/Safety Check
Align bolt with receiver and work forward past bolt stop button to reinstall.
2. Once bolt is reinstalled, ensure once again that the firearm is not loaded. Put safety to the on position and ensure that the trigger does not release the hammer when pulled.
