Hiperfire EDT Heavy Gunner Trigger Assembly


Out of stock

The Enhanced Duty Trigger (EDT) Heavy Gunner is a single-stage trigger and an exceptional upgrade for your MIL/LE/SWAT or utility rifle.  HIPERFIRE’s EDT triggers are re-engineered from the ground up, are smooth, accurate and include features of higher tiered trigger designs.  The EDT 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 while giving the user a crisp, clear break with very short over-travel and positive reset you can both feel and hear.  The EDT Heavy Gunner is reliable for use with many different types of ammunition and in any situation!  Installation is easy, and your satisfaction is backed by HIPERFIRE’s 110% Money Back Guarantee, should you not be completely satisfied, simply contact HIPERFIRE directly.

Although compatible in both AR15 and AR10 platforms, we recommend the 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.  Consider the HIPERFIRE EDT Sharp Shooter for your standard 5.56 NATO / .223 Wylde AR builds.

The 3 EDT (Enhanced Duty Trigger) variations 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: 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 EDT trigger feature can minimize this occurrence.
