Jmt Black Ops Straight Single Stage Drop in Trigger Review
The driblet-in trigger kerfuffle of last year all merely halted the flood of new drib-in triggers for the MSR platform. Some companies scrapped their plans for new triggers. Others, like James Madison Tactical (JMT) kept pushing on, determined to see their original design (non a re-make of another trigger) become a commercial reality . . .
In tardily 2016 JMT released their get-go premium single stage drib-in trigger for the MSR/AR-15 platform, the Saber. I remember Rainier Arms offered the trigger at the promotional price of $89 – a hell of a deal. I know a few folks who bought the trigger blindly at that toll and they're quite happy. But even without a auction tag, the trigger comes in at a bargain toll of merely $99.95 MSRP.
JMT adamantly advises the use of anti-rotation pins. To promote this do, the Saber now ships with a set of pins and an Allen key. Keep in mind, it helps to have a second i/64-inch hex key when installing the pins and exist sure to use blue thread locker.
In-hand, it was tough to come up to terms with the fact that I was holding a sub-$100 drop-in. At that cost y'all won't find many critical firearm components with machining equally nice as the Sabers', permit solitary an unabridged trigger pack. The guys at JMT come from the aerospace industry and the required level of attention to detail and quality shine through with this trigger – both figuratively and literally.
JMT's "signature" metallic silver anodized aluminum housing snuggly contains all components. The hammer, disconnector, and Sabretooth tiger-esque skeletonized trigger shoe are precision-cut 17-iv, super-shiny stainless steel specimens of premium CNC/EDM machining.
The trigger shoe's design not only helps save weight (3.456 oz. without pins), it feels fantastic. Sporting a vertically convex contact surface and precision edges, the trigger finds your finger faster and lets you know its boundaries without biting.
Before installation, I sent the trigger to Jeremy South. for due diligence with the Dvorak TriggerScan, which produces a graphical representation of the mechanics of the trigger. If you've seen Jeremy's highly-popular AR-15 Drop-in Trigger Rounds-up, you're already familiar with the format. If you haven't, check it out or you're missing out.
As you lot tin run into above, the TriggerScan graph for the Saber depicts characteristics of a quality trigger. The user'due south experience with the trigger will brainstorm with rock-solid, absolute-zero take-upward reminiscent of the highest-quality triggers. With 3.66 pounds of pull by mode of the barely noticeable 0.05 inches of glassy pitter-patter, the Saber rapidly rolls-over and breaks very crisply. The trigger's over-travel was recorded at a very respectable 0.03 inches, and may well be the one of only a few areas JMT could improve on their blueprint.
Admittedly, I have a sensitive trigger finger. During reset I felt something I hadn't felt in whatever other drop-in. At get-go I mistook it for a "glutinous" or slow reset, which tin be caused by the tension screw backing out. And afterward talking to JMT and trying several other Sabers, I was unable to put my finger on what I was experiencing. Finally, afterward comparison the TriggerScan to Jeremy's library of graphs, I accept my answer.
All but one graph I compared the Saber to showed reset points well after their pause point. The JMT Saber, however, is the just trigger with its reset point very shut to its break betoken. For the record, it's slightly after the break point (altitude indicated in cerise in paradigm above). Then I believe what I was feeling was the later on than "normal" reset.
So is this good or bad? I believe this is a great characteristic! Closer distance between break and reset points, combined with zero take-up and short creep is an first-class recipe for super-fast shooting. The trade-off? Over-travel actually matters. So, simply similar with whatever trigger, information technology may take some fourth dimension at the range to dial-in the correct muscle memory to crush that slight over-travel. On paper, however, the JMT Saber is an excellent prospect for, say, 3-gun or that bucket-list helicopter pig chase burglarize.
What's more; because Jeremy has built that overnice library of TriggerProfiles, we can overlay them against other triggers on the market.
A popular competitor in the AR-15 drop-in marketplace is the CMC Unmarried Stage trigger (reddish line in graph above). When we overlay the JMT and CMC TriggerScans, the differences become crystal clear. The CMC breaks with less applied force, but has more creep. The Saber tops the CMC at the starting line and besides breaks the finish line start. Noticeably, the Saber requires increased force throughout the majority of its short creep, while the CMC hits its stride early and coasts downhill to its interruption betoken.
When we await at the Saber versus the ultra-premium Elftmann Match trigger ($259 MSRP, red line in graph above), they near match each other step-for-pace out of the blocks, which is impressive. The Elftmann finishes the race before the Saber can even break, but JMT'south trigger passes the line only three-hundredths of an inch later. That'southward darn practiced for a trigger that costs a picayune more a third of the price of one of the all-time drop-ins on the market.
To engagement, I have upwards of v hundred rounds downrange across five dissimilar Saber triggers in five different builds – three friend's firearms and two of my own. My experience with the trigger has been pleasantly consistent and impressive. Each of the v triggers exhibited the characteristics depicted in the TriggerScan graphs; zero accept-up, no grit but a smooth curlicue-to-intermission, and about intermission-indicate reset after minuscule over-travel.
JMT has leveraged their aerospace industry expertise to create a fast, reliable performance trigger at a price that is tough to pass up. Later on talking to the guys at JMT for the past half-twelvemonth, it is strongly apparent that they are dedicated to continually improving their current products while developing new ones. I am happy to enjoy the Saber while I wait to run across what they put out next.
Specifications: JMT Saber Single Stage Drib-in Trigger
Price every bit reviewed (one trigger shoe only): $99.95 MSRP
Ratings (out of five stars):
Ease of Installation: * * * * *
The Saber has fit well into every lower receiver I have tried it in. I take encountered zilch issues with regard to pinhole alignment. Although anti-rotation pins are recommended, the set spiral installation option works just every bit well.
Pattern: * * * * *
With a near-saturated drop-in trigger market there wasn't a lot of room for innovation when JMT brought the Saber to the party. Yet, they delivered a high-quality trigger design that exhibits an outstanding residue of performance features and price, while closing the gap between the suspension and reset point.
Performance: * * * * *
Zero take-upwards. Minimal, but glass-smooth creep. Reset point simply later on pause betoken. The JMT Saber's performance plain outpaces its price tag.
Trigger Shoe: * * * * *
The skeletonized sabretooth-style trigger shoe is top-notch and a groovy marriage of office, aesthetics, and weight-saving measures. It is extremely well-machined and finished. The convex face of the trigger is very comfortable.
Overall: * * * * *
The JMT Saber unmarried stage drop-in trigger is a functioning trigger at a bargain cost, wrapped in a sharp aesthetic. This trigger will remain on my list of become-to triggers for builds of any type. It is definitely worth a look (and feel) for your next AR-15/MSR/PDW projection.
