HIPERFIRE HIPERTOUCH EDT3 Trigger
HIPERTOUCH EDT3 High Performance, Enhanced Duty drop-in AR15 & AR10 Fire-Control
The HIPERTOUCH EDT3 (Enhanced Duty Trigger) fire-control drop-in is a high performance, high precision, service rifle upgrade and recommended for AR-15 and AR-10 type rifles.
The HIPERTOUCH EDT3 features a duplex, or two-position trigger bow. Place the finger high in the curve and the pull weight is approximately 5 or 6 lbs with the supplied red hammer spring installed. Or, with the finger riding low on the vertical tip, the weight is approximately 4 or 5 lbs. when the supplied green hammer spring is installed.
This trigger is directed to DMR use. Run the finger high in tactical situations, or run it low in longer range precision scenarios. It’s also appropriate for home defense and hunting applications as the trigger weight is higher than the 24 series triggers. It’s the “AR” fire-control upgrade we’ve all dreamed of. A helpful read of the FCG Trouble Shooting Guide relates some issues customers will have during and after installation that are easily resolved with attention to detail and common sense. Found in the guide is this graphic, AR-15LowerCavity.PDF. HIPERTOUCH FCGs may not work in lowers with FCG holes that are outside the MIL-Spec toleranced dimensions shown in RED.

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.
This trigger is directed to DMR use. Run the finger high in tactical situations, or run it low in longer range precision scenarios. It’s also appropriate for home defense and hunting applications as the trigger weight is higher than the 24 series triggers. It’s the “AR” fire-control upgrade we’ve all dreamed of.
