KE Arms in conjunction with M&M Manufacturing is pleased to announce the release of the SLT-2 Sear Link Technology ARC Blade Trigger



M&M Manufacturing designed the Sear Link Technology trigger to address the short comings common to most AR15 trigger designs.  Produced and distributed by KE Arms, the patent pending sear link system eliminates the traditional disconnector, resulting in a smoother and more durable trigger.  As the hammer is pushed out of the way by the bolt carrier group, it does not impact any other parts of the fire control group.  Without a disconnector for the hammer to drive through, longevity and durability of the trigger system are increased especially when used with higher speed BCGs found in pistol caliber carbine blowback systems.  The function of the sear link system also allows the firearm to be placed on safe with the hammer either cocked or forward, something unique to aftermarket trigger systems.  This simplifies the manual of arms and reducing the possibility of a negligent discharge when transitioning or clearing malfunctions.  Finally the moving parts of the SLT are isolated in the forward front section making them much less susceptible to debris and fouling than traditional designs.

Although the SLT-1 with curved trigger has been successful since its release in early 2017, there was still room to make it even better.  End user feedback and input from the KE Arms Shooting Team led to the development and release of the SLT-2, featuring the ARC Blade trigger.  The new trigger improves the tactile feel of the reset, making the shooter more aware of when the trigger has moved forward to the reset point.  The surface of the ARC Blade makes the pull feel consistent regardless of trigger finger placement.  The SLT-1 maintains the curved trigger, but now also features the improved tactile feel of the SLT-2.

Yes, it is possible to make a full auto version of this.  However unless there is a military or Law Enforcement agency request for a large number of full auto triggers its not something we will pursue.  There are millions of semi-auto AR15s in circulation (as well as PCCs like the MPX) that can use a semi trigger with these benefits.

Regards,

Making the trigger pull much lighter causes reliability issues.  Most people guess the trigger pull is 3-3.5 pounds when they try it in person if they haven't seen specs or an ad.

The improvements were all based around end user feed back in the MPX.  Prior to release I shot 5000 rounds in testing on an MPX.  I stopped shooting the MPX when we came out with our own 9mm Glock mag lowers.

Since release we have improved the SLT triggers to further improve durability and reliability in the MPX.  Everything manufactured since November 2017 includes these improvements.  These improvements include heat treating all the parts rather than just the hammer, and adding a return spring under the sear.  You can see the return spring in the gap between the hammer and the housing.

Since these improvements we've had 2 returns for use in MPX; they were full of unburned powder and carbon; there was no wear on the parts or breakage.  Simply cleaning them made them operational again.
