The Genius of the HIPERTOUCH® Fire-Control
HIPERTOUCH® FCGs have uniquely solved two problems with stock AR triggers and AR trigger upgrades in general: 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 sear optimized.
Hammer Fall Energy: Even with trigger weight, high energy MIL-spec hammer fall is maintained. The best of two worlds.
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.
The EDT 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 EDT 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 EDT pull weights, you’re very close to appreciating what the EDT will feel like.
Third, the EDT 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 EDT’s hammer and trigger mechanical advantage pioneered by HIPERFIRE in its design of the 24 product family has been included. So, the EDT hammer still strikes well within MIL-spec’s hammer energy range with lowered trigger weight.
Fourth, the EDT 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 EDT 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 EDT 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 EDT trigger feature can minimize this occurrence.
