There have been stories over the years of aftermarket triggers that have run afoul of the ATF – with the agency deeming some to be “machineguns.”

However, Delta V has introduced its Gen-2 3MR trigger for the AR-15 platform, which it boasts as the only advanced assisted-reset trigger technology on the market today that is expressly approved by the ATF and is non-NFA classifiable. It can deliver both speed and accuracy courtesy of its three-mode selector system and precision-engineered assisted reset design.

Upgraded from the original 3MR trigger system, the Gen-2 3MR features an improved disconnector engagement surface geometry that promises smoother, more precise, and quicker sear engagement transfer during reset and in the shortest distance possible.

The Delta V Gen-2 3MR is a unitized, drop-in trigger system that be easily installed into standard AR-15 and AR-10 receivers that utilize a Mil-Spec-style fire control group with the small 0.154-inch trigger and hammer pins. The system further includes a proprietary ambidextrous selector that regulates the trigger’s three operational modes: safe, semi-auto, and the Delta V patented and enhanced 3rd Mode.

In the standard semi-auto mode, the Gen-2 3MR presents single-stage operation with zero take-up and minimal sear travel for a clean, crisp, and efficient break that is meant to minimize shooter-induced shot disturbance and enhances accurate point-of-aim, point-of-impact performance. In its “3rd Mode,” the Gen-2 3MR uses its positive reset function, which transfers energy from the bolt carrier through the trigger assembly to quickly and precisely engage the trigger with the hammer sear. The slightest forward movement of the trigger finger establishes the reset, making the trigger ready for the next shot.

Delta V’s Gen-2 3MR also allows shooters to fine-tune the trigger’s positive reset characteristic to achieve maximum reset speed with minimum forward trigger travel. This can be done by simply adjusting tension in the spring and plunger assembly in the back of the hammer, which interacts with the Gen-2 3MR’s exclusive reset assist arm.
