When I was young, it was the BMF activator, a crank attached to the trigger guard of your Ruger 10-22 that pulled the trigger for you 4x/ turn.  I never dropped the money for that device because I didn’t like the change in functionality of the gun. What if I just wanted one accurate shot? Next came slide fire type stocks. I watched the videos and saw the rate of fire, but this still didn’t do it for me. I understood that the slack in the stock and the pressure from the round firing would effectively reset the trigger for you. It seemed to work great, but had a learning curve and I wasn’t sure what effect the movement in the stock would have on accurate single shots. I then heard about the Tac Con 3MR.
This product is a replacement trigger that is reset with the action of the bolt. In the first position, it is on “safe.” It functions as a normal trigger in the second position with a 4.5lb pull, and has a reset function on the third position with the same 4.5lb pull. It seemed interesting, but also seemed expensive. I decided to drop the dime and persuaded them to sell me one at a slightly discounted price with my instructor credentials.
It came in a small plastic hanging container cushioned with foam inside. The parts were clean and free of burrs and the finish was consistent on all of the parts. A small laminated card purporting to be an opinion letter from ATF accompanies the part and assures the user that the government will not be angry at you for owning it. Installation is easy for anyone who has installed an AR trigger before. In fact, it is easier because the trigger, sear and hammer are all in a self-contained group.
After installing the new selector switch (included) and trigger group with the original pins, I was ready to go. I chose to put it into a Spike’s lower that was already marked for select fire- it seemed appropriate. I went down to my range and let the brass fly. At first I tried it on the semi-auto setting. The trigger pull is crisp and even with no perceivable take-up. It was much nicer that the kit I had originally installed. A flip of the switch came next and I let loose.
I have fired full auto before, and this was not it. It was much better. Full auto seems to take shot placement out of the equation and devolves into keeping the muzzle down and generally on target. This was not anything like that. I felt like I was placing every shot that left the gun. The bolt reset the trigger faster than I could dream of doing myself, and I could focus my attention on squeezing and aiming. With 3 30 round magazines of practice, I was reasonably pleased with my performance. I haven’t gotten to the rate of some of the you-tube videos I watched, and Miculek could still out-fire me with a revolver, but I did achieve what I have longed for since I was a boy drooling on the ads in the back of the shooting magazines. I was able to get a cyclic rate faster than I was capable of on my own. I was able to retain (and improve) the single shot function of the rifle. Finally, I discovered quite unexpectedly that I could maintain accuracy in the rapid fire setting. I can imagine this would be a distinct advantage in timed target acquisition competitions.
This trigger is not for everyone: it costs more that the lower I installed it in, even with the discount; it is expensive to rattle off ammo like that; it can be hard on a barrel to smoke that much powder that quickly, but in the end, it was a lot of fun, and that is what gets me to part with my money.
