Quotable: “Trigger reset is incredibly short and positive” – Bob

Bench testing

1) Assembly

JP sent the JP Enterprises Armageddon Gear Revolution Trigger Upgrade for review. Unlike most of the other Fire Control Groups that we reviewed in our Big AR Trigger Upgrade test series, we did not install the JP trigger in an otherwise complete AR15 lower receiver (Model AM-15) provided by Anderson Manufacturing. JP Enterprises chose to send the Armageddon Gear Revolution trigger already installed via anti-walk pins in a complete JP forged AR-15 Lower assembly (model JP-15). To make things even more interesting JP included their Silent Captured Spring (CSC) buffer spring as well as an ambi safety selector, magpul trigger guard, JP branded Hogue overmolded grip and the Exos Defense Ti-7 stock.

2) Hammer drop block

Before our range testing day, we put the hammer drop block in the JP lower receiver to test the JP Enterprises Revolution Trigger  for proper operation and get an undistracted feel for the trigger. This was an important step for us, as it allowed each tester to rapidly switch the hammer drop block to different lowers with different triggers to test the trigger feel for accurate comparison. Similar to the other action shooting competition triggers, I expected an ultra-short travel, light trigger with a short reset. The JP Armageddon Gear Revolution Trigger is advertised as having virtually zero creep and a very short reset, since it was designed for the competitive action shooting arena where speed, accuracy and split times reign supreme. Hammer block testing confirmed that there is virtually zero creep. As in, when the trigger resets, which is audible, it is already pretty much at the wall.

The most striking aspect of the Armageddon Gear REVOLUTION trigger is the unique cylindrical trigger bow. It is basically a hollow polymer cylinder on a straight trigger rod which allows the polymer cylinder to rotate… or revolve… about the trigger rod. Try as I might, I can cycle the trigger over and over and over and never seem to be able to keep the trigger from rotating. This suggests that I have a bit too much lateral muscle memory that would likely have translated into a slight deflection of the rifle as the trigger is pulled. Anything that moves the rifle off of the aim point during shooting degrades accuracy. The theory here is that the JP Armageddon Gear Revolution Trigger‘s roller trigger helps the shooters finger quickly find the neutral position for a straight back pull instead of pulling off to one side. In practice, I certainly feel the rolling motion as the trigger makes it difficult to pull to one side or the other.

JP Enterprises Armageddon Gear Revolution Trigger pull scale3) Trigger pull scale
Measuring trigger pull weight is pretty simple:

  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 weightsJP Enterprises Armageddon Gear Revolution Trigger close up

The JP Enterprises Revolution Trigger at a consistent 3.25 Lb on each of 3 pulls with our trigger pull scale. JP chose the yellow hammer spring and yellow trigger spring configuration, which they advertise as the competitions/recreation setup, providing between 3.0 and 3.5 Lb trigger pull weight in most lowers. Other optional spring configurations range from 3 Lb to 4.5 Lb pull weight.

The consensus among our testers is that the sub-3 Lb range is too light and and the lack of pre-travel in the trigger might be a safety concern for the uncontrolled hunting environment. The Armageddon Gear Revolution Trigger is designed as hard-core, dedicated action shooting competition trigger and we think the pull weights available are well suited for that type of shooting.

4) Pre-travel & Over-travel

We measured total travel the tip of the trigger at about 1/16 of an inch. With no perceptible pre-travel, or creep, that leaves about 1/16 of an inch of over-travel, with a positive, audible reset of about 1/16 of an inch. Your finger won’t have far to move to run this trigger fast.

 The Results

AR trigger upgrade WMD Guns NiB-X trigger 100 yards bench100 yards

All 5 shooters shot 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 Armageddon Gear Revolution Trigger performed under slow, controlled fire. Since the JP roller trigger is designed for action shooting competition, I expected it, as I had with the other competition triggers, to feel too light and touchy for longer range shooting. What I found was that the light trigger pull and lack of pre-travel meant that I had to focus more on when to release the hammer… because that is basically what you get with the action shooting competition triggers… precise control over when the hammer releases. Distance shooting is usually characterized more by a desire to be surprised when the trigger breaks so that the shooter doesn’t involuntarily react to the trigger break with any sort of twitch or flinch that might move the gun and make the shot miss it’s mark. While I think the action shooting competitions triggers are fine for casual longer distance shooting, they are likely not what most people would choose for serious distance shooting. Specifically, I liked the feel of the JP roller trigger when distance shooting and put an extra 10 rounds or so down range with it to try to discern whether the roller was making an impact on my accuracy, or just distracting me, as it feels markedly different than any other trigger I have ever shot with. It is going to take many more trips to the range to sort this out for certain, but I a committed to getting to the bottom of this and will put in as many trips to the range as are necessary to offer a positive opinion on this. 😉

ar trigger upgrade review close range carbine shooting
 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. We mentioned in the reviews of the non-competition triggers that the competition triggers felt a bit light during this stage of the test. We actually had one premature shot at the short range firing line because the shooter meant to just find the trigger with his finger, but instead put just enough pressure to allow it to fire  (sorry, don’t recall which of the competition triggers it was. We didn’t write it down, as the shooter quickly said it was his fault, not the trigger). No one was hurt, and it wasn’t the triggers fault… it was just operating as designed. However it highlights the reason why most people prefer a bit heavier trigger with a bit of creep for a tactical environment. That said, the Armageddon Gear Revolution Trigger performed well in this portion of the test with no complaints from any tester. Josejuan noted that for this type of shooting he would not use the pad of his trigger finger on the trigger, but instead would roll his finger forward so that the trigger rested in the first joint of the finger. With my big hands and longer than normal fingers I had a tendency to wrap my finger too far around the trigger like I was grabbing it with a meat hook, which likely induced a bit of deflection. I suspect that adding a spacer to the rear of the pistol grip, or changing to a modular grip that allows for different thickness backstraps to be used would take care of this issue. While this issue has more to do with fitting the AR to my abnormally large hands, I only found it to be an issue on the JP roller trigger, given that the angle my finger naturally sits on the trigger induces a bit of roll on the trigger. Clear as mud? I will discuss this in the full JP Armageddon Gear Revolution Trigger review video.

JP Enterprises Armageddon Gear Revolution Trigger Speed Hammer40 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. Similar to the tactical carbine shooting, the JP Armageddon Gear Revolution was in it’s element during the plate rack duels. The short, quick reset really seemed to help with getting off a string of aimed shots quickly.  The JP Speed Hammer is likely a big part of this, as it reduces the swinging mass of the hammer for improved lock time. If you believe that little details make a difference in performance, then the speed hammer is an interesting study. The JP Speed Hammer is made from A2 tool steel, hardened to 58 Rockwell all the way through, then press fit with a stainless pin boss. I really felt that the limiting factor in my speed on the plate rack was how fast I could move my finger.

I shot the JP roller trigger equipped lower as #6 out of 9 and just after the Hiperfire 24C. Both are VERY fast triggers that offer a unique finger placement option (Hypershoe vs roller). Whether you would prefer the wider finger contact surface that the hypershoe provides or the cylindrical roller surface of the Armageddon Gear trigger is difficult to sort out in a review. Our test team was not unified in our opinions of which feels “better” or offers the most advantage to the shooter. However, we were in agreement that both of the triggers are exceptional and offer a unique feel.

 JP Enterprises Silent Captured Spring AR buffer40 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. It is no surprise that the light trigger pull and ultra-short reset made the JP roller trigger very fast. The JP Armageddon Gear Revolution trigger was so smooth that getting back on target quickly was a bit easier than any other setup. This is likely due to the added bonus that JP Enterprises paired with the roller trigger, the JP Silent Captured Spring buffer. With a totally different operating mechanism than a standard AR buffer tube, buffer and spring assembly, the SCS is supposed to make the buffer operation smoother and quieter. As far as I could tell, it did.


The Armageddon Gear Revolution Trigger is hard-core competiti0n shooting trigger. Period. It is not intended to be a jack-of-all-trades, instead excelling at one thing: fast fire control that does not negatively impact accuracy.

Gear Score
Our whole team rated this trigger as one of the top in our test.

According to John Paul Gangl, the founder and head of JP Enterprises, many in the competitive shooting community thought he was off his rocker when he set out to create a company selling really expensive AR platform components and full rifles. JP, as he is widely known, answered my questions and told me about his company, product lines and vision as background for this review and our larger Big AR Trigger Upgrade Test. As the interview progressed I began to understand both why folks may not have bought into his vision right away, and how he has converted many of the doubters with a commitment to quality and innovation that few dare to pursue.
The AR platform was not initially designed as a precision competition rifle. JP professed to be a bolt gun snob back when he owned a gun store and gradually warmed to the platform only after identifying a few ways to coax better accuracy and speed out of an AR. Jump ahead through 40 years of competing at the top levels in a variety shooting formats (many with the AR) and it isn’t hard to see that JP is a good shooter. Translating that into cutting edge competition rifles with a variety of innovative components of his design and selling for multiples of what many shooters consider an “expensive” rifle… well, that would take more than shooting skill. I can see why some doubted the sanity of his vision.

JP is not an engineer, but he described a rather engineer-like methodical iterative approach to evolving and improving his products. The process went something like: evaluate the platform, identify the biggest impediment to getting the performance he wanted, imagine a way to improve that function, translate that idea to functional parts or assemblies… and start the process over. Over time, he has made both incremental and major component improvements, but done so with the big picture in mind so that the end product meets the needs of the folks that are willing to spend to get the best. Lots of brands shoot to be the best and talk about a commitment to quality and innovation. JP is a rather convincing spokesman, but the products that his team produces speak louder and seem to have validated his vision.

As I write this I am reminded of how Jason, our resident AR builder and the most experienced with the AR platform among the Gear Report team reacted when I said that was sending a lower for our test. The reverence in his voice, how he gently picked up the JP lower to inspect it when it arrived, the look in his eye whenever he talked about JP products … especially the look when he said that he didn’t expect to ever own a JP rifle, as they are out of his price range… Between that and talking to JP himself it is hard to not automatically revere anything produced by JP. I try to see past Jason’s very manly man-crush on JP at the product itself. Is the JP Armageddon Gear Roller Trigger in this review really better than the Hiperfire Hipertouch 24C Competition trigger that Terry Bender and his team produce? I don’t know. Frankly, I give both triggers top marks and think that a competitor could hardly go wrong with either of the innovative triggers with out-of-the-box trigger bow solutions. Pairing the JP trigger with their Silent Captured Spring bugger system and JP-15 lower with a premium stock surely showed that JP is serious in his holistic approach to the AR, that improving one part (the trigger, in this case) is good, but not good enough. What I am confident of, however, is that both JP and Terry will continue to drive towards perfection, one incremental innovation at a time.
JP said that he wants to send his adjustable gas block and handguard solutions for testing next, and I look forward to gaining and sharing a better understanding of the JP Enterprises product line.

GearReport logo Round AR15The 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.
