Quotable: “For its intended use vs value I give it a 4” – Jason  (on a 5 point scale with 1=terrible & 5=love)

1) Assembly

We received the Hiperfire EDT trigger  as a review sample direct from Hiperfire and installed it in an otherwise complete AR15 lower receiver provided by Anderson Manufacturing. Installation is simple and straight forward thanks to the incredibly well written instructions included in the package and the easy to follow installation videos online at the Hiperfire website. I have yet to find any other trigger with such clear illustrations and step by step instructions as are included with all of the Hiperfire triggers.

In a nutshell (simplified, so refer to the official instructions to be sure each step is completed properly):

  1. install the disconnector spring
  2. install the trigger spring
  3. align the disconnector on the trigger
  4. drop the trigger into the trigger well
  5. use the alignment pin to assist in aligning the trigger and disconnector pin holes with the mag well trigger pin holes
  6. install the trigger pin
  7. install the hammer spring on the hammer
  8. place the hammer in the trigger well
  9. use the alignment pin to assist in aligning the hammer pin hole with the mag well hammer pin holes
  10. install the hammer pin

Overall, I found the EDT not as easy to install as the 24 series Hiperfire triggers. The EDT has fewer parts. However, the spring tension is such that aligning the disconnector and trigger with the trigger pin was more difficult than the 24 series triggers. Thankfully, Hiperfire included a small rod about 1.5 inches long with a taper at one end. This “alignment pin” was a huge help in getting all of the holes aligned so that the trigger pin could be inserted. Installation was about the same as a stock mil-spec AR trigger. Not difficult, and it seems manageable for a detail oriented hobbyist.

Chosen configuration: The Hiperfire EDT trigger comes with 2 Hammer Spring options. The Green spring is reported to deliver a trigger pull weight of not less than 4.5 lb , while the Red spring is reported to deliver a trigger pull weight of not less than 5.5 lb. We chose the lighter Green spring for this installation.

2) Hammer drop block

Before heading to the range to make expensive noise, we put the hammer drop block in the  Anderson Manufacturing lower receiver to test the Hiperfire Hipertouch EDT trigger for proper operation and to get our heads around the trigger’s feel. This was an important step for us, as it allowed each tester to rapidly switch the hammer drop block to different lowers and test the trigger feel for accurate comparison. We expected the Hiperfire EDT trigger to feel quite a bit like a mil-spec trigger. However, we found the Hipertouch EDT trigger trigger to be noticeably better than a stock mil-spec trigger in trigger pull weight, crispness and smoothness.

3) Trigger pull scale

G.P.S. Trigger pull ScaleMeasuring trigger pull weight is pretty simple (click here if you need a trigger pull scale):

  1. clamp the magazine well block in the vise,
  2. slide the upper onto the magazine well block. So, the upper is completely stable and not subject to movement during trigger testing,
  3. cock the hammer by hand,
  4. reset the peak weight ring on the trigger pull scale,
  5. place the trigger pull scale test arm on the trigger in the location that you will place your finger when shooting,
  6. pull gently aft on the trigger pull scale until the trigger releases,
  7. record the peak weight from the trigger pull scale
  8. lather, rinse, repeat 2 more times
  9. average the 3 pull weights

The Hiperfire Hipertouch EDT trigger delivered trigger pulls of 5.0 Lb, 5.5 Lb, and 5.0 Lb for an average of 5.17 Lb.

Pretty respectable for a Duty Trigger that competes head to head with mil-spec triggers, where average trigger pull weights in the 7 Lb range are considered normal. However, the Hiperfire EDT is the heaviest trigger pull of any of the trigger upgrades in our test pool. We don’t say this as a negative. Each AR trigger upgrade that we test is designed with a specific purpose. The Hiperfire Hipertouch EDT trigger is designed as a workhorse to be carried in situations were an ultra-light trigger pull would be a liability.

4) Creep & Overtravel

We measured total travel the tip of the trigger at nearly 3/16 of an inch. That is split nearly 1/8″ of creep and 1/16″ of overtravel. Although I have to admit that the EDT felt very different to me when pulling with my finger tip vs resting the trigger in the first joint at the end of my finger. With the finger tip I could perceive practically no creep at all with a very crisp break. With the trigger in the first joint of my finger and a slow pull I could get a bit of mushy creep before hitting the wall. In practical terms, when shooting quickly with a firm trigger pull the EDT feels great. It is not designed to be a long range precision shooting trigger, which may explain the different feel when shooting it with a slow easy pull.

 The Results

Given the target market for the Hiperfire Hipertouch EDT trigger, we expected it to be a better-than-stock option for most tasks and a good budget upgrade. However, our test pool is littered with highly refined fire control groups and competition triggers. Can a sub $100 trigger upgrade really be expected to compete with such high-end AR parts?

100 yards

All 5 shooters slung five rounds of American Eagle 55 grain .223 Remington at small numbered paper targets from benches with shooting rests or sandbags at 100 yards to get a feel for how the Hiperfire Hipertouch EDT trigger performed under slow, controlled fire. While I noted a bit of mushy creep on one of the 5 shots, the opinions of the other testers were varied. Comments about creep ranged from: “More creep than I would allow in a personal rifle” to “none”.  Reset was referred to as positive, clean, crisp, audible.

 Short range tactical carbine

Chris from Three Pillars Shooting, LLC and Bob, our other NRA instructor collaborated to run the team through basic 3-10 yard quick target acquisition, rapid shot strings and short mag shoot-reload-shoot drills. Similar to the WMD trigger, in this scenario the Hiperfire Hipertouch EDT trigger performed very well, with a great balance between trigger pull weight and a solid trigger feel. The heavier pull of the EDT was noticeable. However, some of the competition triggers felt a bit light in this shooting scenario. Given that tactical carbine work is a good fit for the design of the EDT, this is a good place to mention how Hiperfire overcame a common problem with mil-spec fire control groups: debris in accumulating in the disconnector. The addition of what I will call drainage holes in the disconnector slot allow carbon and other debris someplace to go where it won’t interfere with the mechanical function of the fire control group. Hiperfire calls this “self cleaning” and it sounds like a good description to me. There is also more clearance under the trigger rear of the trigger to reduce the likelihood that dirt, blown primers or anything else will prevent  the trigger from returning and allowing the hammer to reset. Since the Enhanced Duty Trigger is designed for use in more challenging environments, under more critical circumstances, the seemingly small improvements could make a big difference.

40 yard plate rack

A 2 shooter duel to see who could hit the most of the 6 plates of 8 inch diameter in a horizontal row at 40 yards. Again, similar to the WMD trigger, the Hiperfire Hipertouch EDT fire control group put in a respectable showing in the plate rack duels, but finally started to show a bit of disadvantage against the lighter, shorter-reset competition triggers. While still a massive improvement over the stock mil-spec FCG, the Hiperfire Hipertouch EDT trigger felt a bit heavy and slow compared to the highly tuned triggers in the test.

 40 yard steel silhouettes

This was less formal with 2 shooters competing to see who could put a string of shots on their steel silhouettes most rapidly. We found that the competition triggers excelled with their ultralight trigger pulls and ultra-short resets. As with the 40 yard plate rack duels, the Hiperfire Hipertouch EDT trigger felt smooth and solid, inspiring confidence, but also felt a bit heavy and slow.

As noted in our AR Trigger Test Preview, Terry Bender, the Hiperfire CEO wasn’t just willing to pit his triggers against the competition, he was EAGER While every other manufacturer in our big AR Trigger test sent one model of trigger for evaluation, Hiperfire sent all 5 current production triggers. Terry, a mechanical engineer by training, created a very innovative design for the 24 series triggers, adjusting the geometry and mechanisms within the AR trigger group.

The Big AR Trigger Upgrade Test

We tested 9 AR platform trigger upgrades from 5 different manufacturers to identify:

  • Which AR trigger upgrade is the best value?
  • Which AR-15 and AR-10 triggers are best suited for hunting, competitive shooting, personal defense, duty rifle?
  • Which AR trigger do we like best?

Starting with a just barely broken-in “mil-spec” trigger group as our “control”, our team of 5 testers assembled and dry fired each AR FCG on the hammer drop block to get a feel for each trigger, measured trigger pull weight with a trigger pull gauge, then shot each trigger in long range, tactical carbine, and competitive shooting situations to assess each fire control group in a real-world setting. We shot nearly 2,000 rounds down a combined 6 AR uppers so we could provide the most comprehensive trigger upgrade review possible.

Huge thanks to Ammunition Supply Company, who kicked in 2,000 rounds of bulk 55 grain ammo for this test.
