KE Arms SLT-1 Sear Link Technology Trigger for Ar15 4.5lb Single Stage Drop In

The KE Arms SLT-1 Sear Link Technology Trigger for AR15 delivers a 4.5 pound single stage pull with minimal takeup and overtravel, an ultra-crisp break, and an improved tactile reset that dramatically reduces split times while offering simple drop in installation for a seamless upgrade to your rifle. Engineered around efficient energy transfer, the SLT-1 eliminates a disconnector drive through the hammer, allowing the bolt to push the hammer aside as the gun fires, while forces of the bolt on the hammer are not transmitted into other trigger components, and constant sear engagement keeps the trigger ready to reset and fire. This design also enhances safety, as the geometry allows the safety to be applied regardless of whether the hammer is down or cocked, providing an additional layer of control during administrative handling and malfunctions. Reliability is improved through moving parts sealed in the underside of the housing to resist fouling and debris, and longevity is increased due to no impact on other moving internal parts. Tested across traditional AR calibers and pistol caliber blowback systems and even the Sig Sauer MPX, the SLT-1 drops into mil-spec fire control pockets and is retained with standard fire control pins; the unit weighs 0.15 pounds and is compatible with a wide range of calibers, with noteable exclusions for Combloc 7.62x39mm ammo and certain .22 rimfire AR setups.
