UPDATE: Watch our first-look at the range, as we were lucky enough to give it a whirl.

Phoenix, Arizona based Tactical Fire Control Inc., has just teased out a drop-in trigger group that promises to turn your basic AR into a (nearly) full-auto rifle with no need for the onerous NFA licensing process.

According to TFC, the so-called "3MR" trigger is set up to switch between safe, semi-auto and a third fire control mode which uses a "positive reset" to cut down on shot-times.

The positive reset characteristic is achieved by transferring the force from the bolt carrier through the trigger assembly to assist the trigger back onto the front sear. As a result, this gives the firearm the fastest reset possible.

Looks pretty freaking amazing. And in case you thought this was too good to be true, Tactical Fire Control has a copy of the ATF letter certifying their 3MR trigger as a non-NFA semi-auto trigger.

The 3MR trigger will retail for about $500. The company is accepting pre-orders and says the trigger will be set to ship by early 2014.

You've got to watch this video twice to believe it.
