Note: This will only work on the Rimfire RPRs. It is NOT compatible with the Short or Long Action RPRs. 

Anarchy Outdoors' Extended Magazine Release for the Ruger Precision Rimfire Rifle 

Because of the extra length of Anarchy Outdoors' RPR Rimfire extension, the shooter can drop the mag without removing their hand from the grip, creating a smooth operation for any shooter.

Installation is straightforward and possible to complete at home. With the factory mag release pin and the provided spring, the release stays securely in place.

This extended magazine release is the perfect addition to every Ruger Precision Rimfire Rifle. It meets the mag exchange needs for everything from competitions to practice sessions.

Whale Tail Installation

  • First, it's your responsibility to ensure your firearm is unloaded.

  1. Ensure the safety is on.

  2. Unscrew the action screws from the bottom of the firearm.

  3. Press up on the mag catch housing to release it.

  4. Using a punch pin set, push out the pin holding the mag release into the housing. (Note: pushing out the pin shouldn't require any hammering; do it by hand.)

  5. Unscrew the Whale Tail to allow an easier install.

  6. Install the Whale Tail straight piece in the same manner that the OEM came out. (Note: Ensure that the pin goes through all OEM hardware that is also held into place by the pin.)

  7. Ensure the spring has not bent during the install process. If it has, you can often reposition it using a small punch pin.

  8. Screw the Tail portion of the extended mag release back into the straight piece.

  9. Reinstall the action screws.

  10. Test to ensure everything works properly.

  • Great Mod

    Not difficult to install but I scratched my head at least once. After I wrapped my head around it install was a breeze. Works very nicely and the larger release should have been standard from Ruger. Love this addition.

  • Prefect upgrade

    Posted by Michael Jones on May 5th 2021

    This extended mag release made a huge difference to the RPR. It is significantly easier to locate and release a mag while prone. Works great for NRL22 stages where there is a mag change while on the clock. This should be standard equipment for the rifle. The only slight complaint is that the red used on the mag release is a different shade of red than the Little Big Bertha bolt knob, so they don't quite match. Functionally though it could not be better.

  • What Ruger should have made

    This extender is great quality and easy to install. I Love it. Anarchy Outdoors is a great company to purchase from. Super Fast shipping too.

  • Excellent replacement

    Thanks to CS for helping me correct my mistake and order this instead. The mag release is a lot easier to use now. I'm not sure what Ruger was thinking when they made the lever so incredibly short.
