KE Arms SLT-1 Sear Link Technology Trigger

KE Arms, producer of the DMR Trigger, has licensed the manufacturing and distribution rights for the patent pending Sear Link Technology trigger system from M&M Manufacturing. Before this release, the SLT-1 was tested with tens of thousands of rounds in traditional 5.56 AR platforms, .308 AR platforms, 9mm AR pattern blow back carbines, and the SIG MPX.

The SLT-1 has more efficient energy transfer since there is no disconnector for the hammer to drive through, creating a more efficient cycle due to the bolt simply pushing the hammer out of the way as the gun fires. Additionally, forces of the bolt on the hammer are not transmitted into any other components of the trigger assembly, and constant sear engagement against the hammer means the trigger is always ready to reset and fire. This also improves longevity since there is no impact on the internal moving parts. Reliability is improved because all of the moving parts are sealed in the underside of the housing making it less susceptible to fouling and debris.

Installation is simple–the trigger simply drops into a mil-spec fire control pocket and is retained with standard fire control pins captured by springs inside the housing bushings.

Due to the unique geometry of the trigger, the safety can always be applied regardless of the hammer being down or cocked. When used appropriately this adds another level of safety to administrative handling and clearing of malfunctions.

And…KE Arms is also offering a limited time deal. KE Arms Ambi-Selectors will be included with all orders direct from KE Arms. If you purchase an SLT-1 from an authorized retailer during this time, you will receive a voucher for a free ambi-selector in the package.

I received one of these triggers for review, so be on the lookout for that in the next few weeks!

    Fairly interesting. Other people can get in line though. I doubt it’ll replace all my SSA triggers, but the idea is at least a little novel.

    Might be interesting to compare it to a tuned JP single stage. Personally, I like the idea of being able to safe a rifle with the hammer down.

    The thing I wonder about is how easy is it to clean the inside of the trigger housing should debris manage to get caught there? Still, that looks really slick, and I’m glad to see some actual innovation in the industry.

    Ribbed for the shooter’s pleasure?

    I was thinking it must work with a similar concept as a Sig P320 trigger, and after watching the video, I was right.

    The act of pulling the trigger also disconnects it. The sear is a separate piece that is spring loaded, and holds the hammer until you release the trigger.

    While all the talk of reducing stress, is a little dubious in usefulness… The safety engaging with hammer down, and the lower susceptibility of the trigger to debris is a good thing.

    It is a fair price. I like it.
