The HIPERFIRE Power Drop In trigger kit for the Sig MCX is designed to give reliable operation with a reduced pull weight. Unlike other aftermarket triggers, the PDI from HIPERFIRE will never give you light primer strikers. This is thanks to its advanced hammer face design, which hits with more force than a Mil-Spec M16 hammer, guaranting your gun goes bang when you need it to. The HIPERFIRE PDI Sig MCX trigger assembly is tough enough to use in blowback operated pistol caliber AR platform operated rifles. PCCs are notorious for spraying junk all over trigger components, but the HIPERFIRE PDI is built tough enough to withstand that.

My Second Choice, but still a Winner

by -

This is one of the rare times when I settle for my second pick and it hits the marks! This trigger installed in my MCX Legacy without any issue, and has performed flawlessly for the past few months. Thousands of rounds fired and I have not experienced any malfunctions, not have I experienced too much fatigue while using this trigger. The Finger pad did take some getting used to, as I kept fiddling with it for the first few range trips while getting used to it.
<br>It has performed very well, and I have yet to find ammunition that it does not consistently fire. I'd buy it again, and I'd recommend it to others looking for a crisp Trigger with great feedback.
<br>4.5 Stars out of 5 purely because of the Finger pad and the amount of time it took to get used to using it. 3 Range trips and a lot of position changes to get it just right. Once you have it dialed in, you should be good to go!
