ARAK-21 Barrel Assembly Unit (BAU Only)
The HIPERTOUCH® EDT3 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® name is short for High PERformance TOUCH and EDT for EnhancedDuty Trigger.
The 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. For installation and operational features of the HIPERTOUCH® EDT3 watch the videos in the playlist above. View 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.
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 EDTs were 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: pull weights of greater than 4 lbs. The EDTs meets that specification and more.
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 EDT3 pull weights, you’re very close to appreciating what the EDT3 will feel like.
Second, 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 6 to 6 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.
Third, 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 EDT trigger feature can minimize this occurrence.
The best feature? The EDT3 is only $99 at MSRP.
Well built trigger with no creep. Very easy to install and HiperFire provides you with all the tools needed for the install and switching out springs easily at a later date. Read the instructions and review the part names before installation will make life easier as instructions are written clear with part names but diagram is does not specify which part completely. Will purchase more in the future.
This is a great trigger replacement for anyone upgrading from a standard trigger and needing to stay with a heavier pull. The trigger installs quickly and easily. Your pad sits comfortably on the trigger (in either the upper or lower part, depending on the situation). There is ZERO creep with this EDT3 trigger. I have not had the chance to shoot it yet, but an expecting no issues. Will purchase for all of my future builds.
I purchased two of these triggers so far and have found them very easy to install. No guessing or set screws or reset distance adjustments, just simple , dependable components. The two spring option is fantastic as is the two distinct areas on the trigger that will give you two different pull weights depending on the situation you are in, simply genius to incorporate that type of option into the design. I have used other triggers that required way more set up and didn't have the trigger finger placement option and cost twice as much. Also lets face it, not everyone is an armorer out there but still wants a dependable build, god forbid you need it to protect your family. Well built by great gun people for good gun people.
Excellent duty trigger if you are looking for a smoother/lighter feel while retaining some weight on the trigger for under pressure field use.
I have tried all sorts of trigger confiurations and this assembly is my favorite. Its not super expensive and the trigger pull is smooth and crisp. I like the two different finger holds. Will be purchasing more.
