HiperFire Trigger Shoes Back in Black

HiperFire Trigger Shoes Back in Black

If you have not heard about the HiperFire line of Single-Stage triggers, you should seriously consider them. They are absolutely awesome and the HiperTouch 24C competition model represents a game changing trigger design. Yeah, I know you have heard it all before, however this time it is different. The HiperFire 24C comes with a sharp looking bright red trigger shoe, however now the offer a black trigger shoe as well.

HiperTouch’s founder, Terry Bender, had an idea to overcome many of the shortcomings of “match” triggers. Terry is not just some guy filing down sears and swapping out low power springs in his garage, he is a mechanical engineering consultant. The approach to the HiperTouch design was new from the ground up.

The ultimate challenge for a great tactical/hunting trigger is to deliver a smooth, fast, and flat pre-travel, very fast trigger reset, minimize lock time, assure a crisp light break, and with no noticeable overtravel all while delivering a high hammer fall impact.  With match target triggers, the goals are the same but with even more refinement of all the above, with no perceptible pretravel.

The problem is that many of these trigger design goals are all opposing forces. A smooth, fast, and flat pretravel and crisp light final break all require low forces at the sear which equates to the need for lighter hammer and trigger springs which can lead to light hammer strikes and less reliable ignition. In standard trigger designs, very fast trigger resets, minimized lock times, and high hammerfall impact require heavy springs which creates a crappy feeling heavy trigger. The final dimension is tuning out pre-travel, overtravel, and ensuring a crisp trigger break which are all impacted by the above light or heavy springs. Bad tuning can further impact reliability and safety. The end result is that trigger engineers have their work cut out for them to strike a balance for a great trigger.

The compromise has been either a great single stage trigger that may have a light hammer strike here and there with hard primers, or a 2-stage which delivers a 1st stage pre travel which some claim slows down followup shots.

The magic is delivered via spring cam-ed pressure on the hammer which counteracts much of the hammer spring force within the first couple of degrees of movement around the point of sear engagement. This delivers the perfect situation for a great feeling trigger and break. After the hammer begins to move forward the cam applies pressure the other way and greatly increases the hammer force. This increases hammer fall force, decreases lock time...etc. it's a best of both worlds design and its a totally new trigger design.

The HiperFire has three spring sets (light, medium-light, and medium). Initially, I though the heaviest strongest spring would deliver the heaviest trigger pull however it is the other way around. The strongest spring exerts more pressure on the cam and delivers the lightest trigger feel. This is what the dual spring and cam design of the HiperFire triggers does. It's a mind screw when you first pull back the extra force hammer and have such a light trigger pull.

The Hipertouch 24, 24E & 24C all shared many key features. All of the triggers are AR15/AR10 fire-control compatible with any lower receiver with industry standard .154" receiver pins. The triggers are screw-less "hard" tuned with static precision springs which inherently makes the trigger more reliable than a screw tuned design which can go out of "tune".  The user can tune the trigger at 2,3, & 4 pounds with the three supplied spring sets.

Essentially all three of these semi-automatic HiperTouch HiperFire triggers are identical once the hammer begins to fall and all deliver best in class hammer fall force.  Of course with all these similarities, many will ask what is the difference between them and why woud not just opt for the best automatically. The answer is trigger tuning feel.  You certainly do not want a super sensitive trigger on a duty/defense rifle and similarly you would not want a longer pre-travel trigger on a precision match target rifle.

Many shooters including me will say the 24Competition Model has no pre-travel, no over-travel, and a stunningly light break.  Obviously there is some sort of travel, but it is so little the finger cannot perceive it. Adding the flat straight trigger blade and adjustable shoe increases trigger control significantly.

This is an incredibly fast running trigger which I would love to see one of the top speed shooters run. The splits are incredibly fast. You are going to see more and more 3 Gunners running this trigger simply because it is so fast and light.  That said it is too sensitive for a defensive focused AR15 build in my opinion simply because the trigger seems to lack any perceptible pre-travel at all. To me it most closely aligns to a Geissele National Match trigger but in a single stage design.

The flat trigger design has become a favorite of mine in all sorts of formats from 10/22 rim fire rifles to this Ar15 design.  With the 24C, the tunable trigger shoe offers another advantage for both finger acement comfort and fine tuning of trigger weight. I mounted this in my SanTan Tactical lower receiver and clipped on a 5.45x39 upper which shoots extra hard Russian Surplus rounds.Generally, I will have 1 in 200 that will fail to detonate, however the 24C greatly reduced that soft strike failure rate to only about 1 in 500.  This shows that even the top end of the HiperTouch line can still bring it for both a stunning trigger feel and best in class hammer fall force. The 24C can be used with or without the trigger shoe, however using it adds comfort to the shooter and an additional degree of adjustment for the shooter. Now with the addition of the Black Trigger Shoe, the shooter can choose color as well.

For this build I used a SanTan Tactical Billet Lower with an American Spirit Arms Side Charging Upper and 16” match sub-MOA barrel with Apex Machine Gatorgrip forend. You will see these trigger quite a bit in builds going forward simply because I believe HiperTouch has delivered on a truly innovative design that actually works both theoretically and in practical use.  The price ranges are extremely competitive to other high quality triggers in the market as well... The 24 is a screaming great deal with no tunable trigger in the $185 MSRP price range.

The HiperFire HiperTouch is an outstanding line of triggers which is turning heads in the industry and changing minds about what a great trigger can be.
