Works well. great inclusion with springs - Geissele MPX M4 Rifle Trigger

Watched a quick video for the install and was able to get it done without a hitch. The trigger comes complete and includes 3 levels of springs to tune the MPX. The yellow set worked fine for me. You do need to test to ensure you get proper cycling and extraction. I can’t compare to the Timney as mine was a purchase through the NEX where the 8 inch barrel is available. OP as always was phenomenal to deal with. That’s why I look here first for my fun stuff.
