Most Helpful Positive Review OpMod Hex Trigger & Rise Armament Lower Parts Kit
The Hex Trigger set is simple to install in a 100% lower. It took about 5-10 minutes. Not difficult at all. The 3.5# trigger pull & action is really smooth. The hex shape of it fits my trigger finger most comfortably. Feels great. I wouldn’t have thought the shape would make much difference over a curve shape. But for me, I find the hex shape to be superior to the curve & much more comfortable than the straight shaped trigger. So much so that I ordered a second & then a third. I shoot mostly as a plinker, rather than competitively. But when I shoot, I prefer a setup that yields the smoothest ...

Great lower kit

by a1j7g, Verified Owner from MO, United States Written on February 7, 2025
This is literally the best kit you can buy for the money and it comes with a crisp drop in cassette trigger. Only thing to make this kit better if it included a grip of some sort and ambi safety. But I ordered the grip I liked anyway so it’s still a win win
Pros:
  • Best trigger in the game
Cons:
  • No ambi safety
Would recommend: Yes

single stage

by BP, Verified Owner from TX, United States Written on December 10, 2024
decent single stage trigger. crunchy reset. At first did not think the hammer would fall all the way as it was not going all the way to the receiver letting it down carefully. Under full spring pressure it made it just fine. New receiver, tight fits.
Pros:
  • Single Stage
  • drop in with pins
Cons:
  • reset
Would recommend: Yes
