S&W M&P 15 trigger

I know S&W does their own specs for some parts. I wanna redo my trigger around 3 or 4 pounds if possible. But are the trigger assemblies mil-spec/commercial-spec? And if I can do it myself, can you recommend a kit or parts group?

Look up the hard kits on midwayusa.com

Bud?! What is it with you and midway! Ha

Best thing to do is throw in a set of JP springs. Unless you wanna go out with a Geissele

Ill let ya shoot my ARs and see what you think. One has a 3# and the bull barrel is a 1.5#. Both are Jard 2 stage adjustable. The 1.5# is set up like a bolt gun with no pretravel nor overtravel.
