HIPERTOUCH EDT2 High Performance, Enhanced Duty drop-in AR15 & AR10 Fire-Control

The HIPERTOUCH EDT2 Trigger was designed for the broader high performance shooting market typified by three segments that taken together, demand a unique suite of features at more pedestrian pricing. Those segments are: Law Enforcement, NRA type long range competition shooting, and the multi purpose sport, hunting, and home defense rifle. All these segments have one trigger specification in common: a minimum pull weight of 4½ lbs. The EDTs meets that specification and more.

First, the triggers are user-adjustable to 4½ plus and 5½ plus lbs by simply interchanging two hammer springs. “Plus” means that even after a period of break-in and/or heavy use, the trigger weight will always stay above the two thresholds.

Second, the sear design paradigm used in the 24s has been included making for a very smooth and flat pull with only a hint of creep, a clean break with little over travel, and a fast positive reset. If you have put your finger on a 24E, 24C, or 243G, and can imagine the higher EDT2 pull weights, you’re very close to appreciating what the EDT2 will feel like.

Third, the EDTs sports MIL-spec hammer fall even though the pull weights are less than MIL-spec’s 7-9 lbs. The two hammer springs that give the 4½ and 5½ lb pull weights are even heavier than the stock MIL-spec hammer spring. This is possible because the EDTs’ hammer and trigger mechanical advantage pioneered by HIPERFIRE in its design of the 24 product family has been included. So, the EDTs’ hammer still strikes well within MIL-spec’s hammer energy range with lowered trigger weight.

Fourth, the EDTs’ lock time is faster than MIL-spec, like that of the 24 family, due to the use of the heavier springs and by locating the center of hammer mass closer to the pivot axis, which causes it to spin up to speed faster.

But, there’s more … an entirely new feature found in the EDTs and no where else. Remember, ED stands for Enhanced Duty. When thinking about the needs of Law Enforcement, the Military, the home defender, and the ultimate reliability demands placed on the AR rifle, do you think of very adverse and dirty conditions? Now, imagine when and how you really want that rifle to work? The EDTs’ trigger was designed for that scenario.

First, fine particulate debris and carbon fouling can accumulate in the bottom of the disconnector slot of stock triggers causing the disconnector to jam. If that should happen, semi auto function may be compromised. In contrast, that the EDT trigger slot has holes running the length of its bottom so that the disconnector actually becomes a self-cleaning device, pushing out any debris by that same disconnector toggle action.

Second, notice that the rear underside of the trigger has been raised and the end ramped up and away, increasing the gap clearance between it and the floor of the lower’s fire control cavity. What does that do? Well, if a blown primer cup or bits of gravel should be blown into the lower through the ejection port when shooting prone, they could end up under the trigger preventing it from letting off completely thus preventing hammer reset. Many, especially 3 gunners, have had this very thing happen to them. This new HIPERTOUCH EDT2 trigger feature can minimize this occurrence.

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.

  1. 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.
  2. 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:

  1. Seekins Precision Ambi Safety (60 and 90 deg throws);
  3. Elftmann Slide Safety Selector.
  4. Talon Ambidextrous 45/90 Safety Selector – Tungsten Grey 2 Lever
  5. 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.
