The HIPERTOUCH ECL is HIPERFIRE’s top-of-the-line trigger for AR-15® and AR-10® type rifles. The HIPERTOUCH® name is short for HIgh PERformance TOUCH, 24 for user adjustable trigger weights. The ECL was developed as part of a 3-gun promotion. But, one must realize that this and the other triggers aren’t just for 3-gun. It now sports a new evocative name since its performance eclipses that of even HIPERFIRE’s 24C.
HIPERTOUCH® FCGs have uniquely solved two problems with stock AR triggers and AR trigger upgrades respectively: 1) High Trigger Weight, and 2) Low Hammer Fall Energy.
Trigger Weight: The real culprit behind high trigger pull weight is high sear impingement force that produces high friction. To get around that, the stock “AR” trigger and hammer mechanical advantage was changed and the toggle spring feature added to reduce the impingement force on the trigger sear. Designers of two-stage products changed the functional location of the primary sear; HIPERFIRE®’s design has not, retaining the stock design’s single-stage simplicity. When 2-stage triggers are pulled, the final higher weight stage also signals hammer fall. This can lead to the flinching problem we all know about. Some like to say the better 2-stage triggers have glass rod or candy-cane like breaks to sell the idea that they don’t signal hammer fall. In any case, the HIPERTOUCH® ECL does not signal hammer fall because the trigger weight is constant over the entire stroke.
Hammer Fall Energy: HIPERTOUCH ECL features the unique toggle spring functionality that reduces trigger weight, but while doing so, it also increases hammer fall energy by over 35% over the MIL-spec stock design and every trigger upgrade in the market. This permits the shooter to ignite hard MIL and foreign primers as well as hard to ignite 22 rimfire ammunition.
HIPERTOUCH® FCGs retain Eugene Stoner’s design of simple elegance while remaining very robust, without the gritty feel. Shooting for high accuracy is no longer an almost impossible chore. It’s no longer necessary to improve the stock performance by manually polishing the high-friction trigger and hammer sear surfaces, where the end result was only marginally better anyway.
Ambitious sportsmen and marksmen have been turning to trigger upgrades with varying degrees of satisfaction. The better replacements have been one and two-stage triggers with fixed final weights ranging from between 2½ and 4½ pounds with what some have called a glass rod or candy cane trigger break. Some of these devices require factory or user calibration, maintenance, and/or replacement for wear or doubling. Some of these devices also employ reduced power springs, which have compromised reliable ignition for a “dream” trigger weight.
The HIPERFIRE® “AR” accessory response to those shooter’s looking for a single-stage and very much improved, match quality, “AR” trigger upgrade that delivers high performance is the HIPERTOUCH® ECL. It nests in unmodified standard AR-15® and AR-10® type lower receivers in the same way as stock “AR” triggers and hammers without having to remove the safety selector. It is comprised of three subassemblies: the trigger, hammer, and toggle, spring groups. All the parts are made from carbon steel alloys that have been hardened for wear and strength. It features exceptionally low trigger weights with smooth pre-travel, a very clean hammer release with no report to break, match action response, and faster hammer lock-up. Only now with HIPERTOUCH® trigger and hammer actions does “AR” trigger “squeeze” have real meaning.
Additionally, the HIPERTOUCH ECL also sports the HIPERSHOE® adjustable finger pad as first introduced with the 24C, which can be positioned at five (5) different vertical detent locations along the straight trigger’s bow. By changing location, the shooter can further adjust pre-travel and weight within the broader spring range settings than without it as desired for even more trigger responsiveness. Also, the adjustable pad lengthens slightly the extension of the finger to the pad with respect to the pistol grip, which alters the feel and dexterity of the finger on the trigger for added comfort and/or control. The trigger can be installed and operated with and without the shoe

Q: Trigger Break In Necessary?
A: The triggers are ready to go when installed correctly-. However, the initial feel will change over several tens of dry- or live-fires. Why is this?
The triggers are finished with a MIL-spec process called Parkerize, or heavy Manganese Phosphate, as a rust preventive finish (except for the TH24 with the special Nickel plating). When the trigger is pulled and breaks, releasing the hammer to strike the firing pin, the trigger and hammer sear surfaces scrub off the Parkerize exposing the bare metal. During the process, the feel will change slightly. In fact, initial measurements of trigger weight are unreliable for this reason. But, after 100-200 cycles, the feel and weight will stabilize as the sear completes the self polishing process.
Initial weight and feel is also a strong function of spring break-in, especially the hammer spring. After any of the springs are formed, they are heat treated to remove residual stress. The wire surface becomes noticeably rough. Wires that slide on one another exhibit noticeably high friction. The hammer spring is a double-torsion spring. When the hammer is cocked and when the hammer falls, the coils slide on one another. Initially, this sliding friction is very high. This will contribute to variable trigger weight measurement during initial hammer cocks and falls because the hammer spring supplies all of the friction force on the sear. This hammer spring effect is especially operative on the 24 series triggers, which share the toggle spring system, which makes for a more sensitive tactile feedback that many shooters desire. During the 100-200 dry fires noted above, the hammer spring friction effect is eliminated after repetitive sliding of the coil wires has developed self polished interfacial surfaces. It is not expected that any reviewer would be aware of these facts. Nonetheless, it might have affected the review findings or perceptions.
Q: The Trigger Pin Walks Out. Can It Be Fixed?
A: The trigger pin walks out because it is not captured by one of the hammer spring legs. This can happen in two ways and yes, it can be fixed.
- The hammer spring’s legs don’t seat in the slot made for them on either side of the toggle FRAME so they can’t rest in one of the trigger pin’s grooves and retain it. Fix this by making sure they do. If that doesn’t work, read on.
- The TRIGGER SLEEVE has not been rotated so that its notches match or line up with the notches on either side of the FRAME (this was noted in the installation manual and in the online installation videos). To fix that, take out the trigger subassembly and inspect it. If the SLEEVE is out of alignment, squeeze down on the disconnector to release some clamping pressure on the TRIGGER SLEEVE and rotate the SLEEVE with a tool or your finger nail until alignment has been established. Now the hammer spring legs can lie in the trigger groove to keep it from walking out.
Q: Are HIPERTOUCH 24 series triggers compatible with ambidextrous safeties or other ambi controls?
Safety/Selectors: HIPERFIRE® knows of five safety selectors that will not work with HIPERTOUCH® 24 series triggers:
- Seekins Precision Ambi Safety (60 and 90 deg throws);
- V SEVEN HYBRID 3 GUN/SPORT SELECTORS; and
- Elftmann Slide Safety Selector.
- Talon Ambidextrous 45/90 Safety Selector – Tungsten Grey 2 Lever
- BAD-CASS or BAD-ASS Short Throw Safety Selector
HIPERTOUCH® 24 Series Triggers
The frame component of the HIPERTOUCH® 24 FCG that provides the toggle spring system support is designed to ride on the barrel of semi-auto or “MIL-spec” safety/selectors (not full-auto). This permits normal functional rotation of the safety/selector. An aside: when the FCGs are first installed, some users will notice a little grit during rotation, which is a function of the surface finish on the safety/selector barrel. With a few cycles it will smooth out as the frame and safety/selector self polish.
All four ambi safeties listed do not have a large contiguous cylindrical barrel surface like the stock version; two or more channels or a small diameter barrel have been cut into them that accepts the rear of the trigger when pulled into over travel. The toggle spring frame drops into these channels, which not only relieves necessary compression of the toggle springs but may also prevent free rotation of the safety/selector or even cause rotation of the selector during repeat fire as in the number two case above.
HIPERTOUCH® EDT Series Trigger
The Seekins works in 60 deg throw mode in SAFE and FIRE w/o issue. However, in 90 deg throw mode, the trigger will rotate enough to release the hammer. This is because the trigger tail is shorter than MIL/stock triggers and can move up into the exposed Seekins SS slot just enough to release the hammer when pulled.
Other Ambi Controls: The ambi bolt catch on S&W M&P10s interferes with free rotation of HIPERTOUCH® 24 series triggers. Users have simply removed the ambi control and restored proper function of the 24 series FCG.
