HIPERFIRE EDT AR10 Heavy Gunner Trigger
MIL / LE / SWAT / Personal Utility
The HIPERFIRE EDT AR10 Heavy Gunner Trigger is a single-stage trigger and an exceptional upgrade for your MIL/LE/SWAT or utility rifle. HIPERFIRE EDT AR10 Heavy Gunner Trigger are re-engineered from the ground up, are smooth, accurate and include features of higher tiered trigger designs. The EDT AR10 Heavy Gunner has an improved sear alignment for a flat crisp trigger feel, mass centered hammer design for faster lock times and includes two springs for the user to choose a 4.5 or 5.5 lb pull weight.
The MIL ++ Heavy Duty Hammer Springs create a very hard hammer strike, and high power touch off and gives the user a crisp, clean break, very short over-travel, and positive reset you can both feel and hear. Installation is easy, and your satisfaction is backed by the HIPERFIRE 110% Money Back Guarantee.
Although compatible in both AR15 and AR10 platforms, we recommend the EDT Heavy Gunner for use in .308, 7.62×39 or 5.45×39 AR Builds. These calibers will benefit from the Heavy Gunner’s additional hammer mass. The standard mass hammer is featured on the EDT Sharp Shooter model.

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.
