Yes, however, the JP Enterprises Enhanced Ignition Reliability Trigger Spring Kit is intended for use with JP trigger parts and will not necessarily yield substantial change on standard AR-15 trigger components.

Helpful Positive Review WORKS IN AN MPX! by Supamon, April 28, 2022
I bought this spring set for my MPX carbine gen 2 and they worked great. Made pulling the trigger much more pleasant than the super heavy stock aprings. I wouldn't recommend the weaker version of these springs as you may get light primer strikes.
