With so many aftermarket trigger options available for the AR-15 platform, it’s difficult for any particular one to stand out. That being said, shooting the Hiperfire 24 3G for the first time will definitely leave a lasting impression. Through a bit of mechanical genius, utilizing a couple extra springs and lever arms, HIPERFIRE has created one of the easiest to use, fastest to shoot, and most reliable triggers on the market.

In the package you’ll find the typical two pieces of any trigger system – the trigger and the hammer (each with their own springs already attached), an additional 3 sets of color coded coil springs (blue, yellow, and grey), as well as a little bag of pieces that will probably look foreign if you’ve never installed a Hiperfire before. We’ll get to those in a minute. Oh, it also comes with a colorful HIPERFIRE sticker, which is a very nice size for putting on a stock…

While the 24 3G is not self-contained in a single drop-in housing, you will be able to install the trigger without removing the safety. This is nice because removing the safety involves removing the grip along with a tiny detent and a detent spring which are very easy to lose.

The installation is very simple. First, insert the trigger bow into the hole in the lower, making sure the trigger return spring legs are facing toward the front of the gun. Align the trigger pin and knock it in. The 24 3G comes with the trigger and hammer pins, so no need to buy any separately. Also, they’re identical so don’t stress about which is which.

Now it’s time to install the hammer. Before we do, we need to make sure that the small cylinder is inserted into the proper hole on the back of the hammer. This cylinder is part of the Hiperfire system and must be inserted as shown before installing the hammer.

To install the hammer, make sure the hammer spring legs are riding on top of the trigger pin, then push the hammer into position until the pin hole is aligned with the lower. Knock the hammer pin into position.

This last step is where the trigger’s ingenuity is shown. Take the two spring guide rods (they look like little forks) and slide on the springs of your choice. The blue springs will create a 4lb pull, the yellow springs a 3lb pull, and the gray springs a very nice 2lb pull. Now take the fork ends and rest them in the notches of that little cylinder we installed in the back of the hammer earlier. Use the last remaining piece, a small bar with two holes in it, to capture the springs on the guide rods. While pushing down to compress the springs, rotate this piece into its shelf in the back of the trigger assembly so that it locks into place. Assembly is now done, so do a function test to make sure the safety and trigger are working properly.
