JD45 Posted November 9, 2018 Share Posted November 9, 2018 I've never owned an Ar until I got this M&P Sport II. I want to lighten the heavy stock trigger. Anything under 4.5lbs would be fine. The two stage feel is ok too. But I want a decent break. Can i do it myself with stock parts? I did my own 1911 and other trigger jobs , so I figure it may be easier.

stick Posted November 10, 2018 Share Posted November 10, 2018 Order JP Trigger Springs. Link to comment Share on other sites More sharing options...
Matt1911 Posted November 10, 2018 Share Posted November 10, 2018 Yellow JP springs, polish the contact points and cut the tail off the hammer. Or you can go the easier and much better trigger job route and get a Timney drop in. Link to comment Share on other sites More sharing options...
Darby10 Posted November 10, 2018 Share Posted November 10, 2018 Geissle makes a really nice service rifle trigger group, nickel boron coated, smooth break, for around $70, jp springs are also a good option. Link to comment Share on other sites More sharing options...

ALG milspec is what you’re referring too. You can get a lighter trigger but the pre travel, overtravel and reset will be longer than a higher end trigger.

practical_man Posted November 10, 2018 Share Posted November 10, 2018 Lighter trigger springs and bobbing the hammer are the cheapest path. Bobbing the hammer increases momentum of hammer driven by lighter springs. An easier path is Geissle, Hyperfire, or other after market trigger of your choice.

lefty o Posted November 10, 2018 Share Posted November 10, 2018 use caution when cutting and polishing on stock parts. the surface hardening is very thin. dont take much to cause yourself big problems. for a decent trigger at a modest price, a larue mbt will do what you want.

TonytheTiger Posted November 10, 2018 Share Posted November 10, 2018 I've got one mil spec trigger I wanted to clean up for cheap. I got the lighter springs and a grip screw that adjusts most of the pre travel out. With a light polish job it turned out decent. Not competition decent mind you, just truck gun decent. Now I'll just insert a shameless plug for a trigger I'm selling cheap.... Link to comment Share on other sites More sharing options...

He handed it to me and sure enough, every 3rd, 4th, or 5th shot came out as a pair. Totally unpredictable. It was both scary and funny at the same time.

That is good for up to 10 years in the pen if the wrong person sees you doing that... I'd advise you to stay clear of that rifle until it is repaired... Intent does not matter!

rishii Posted November 16, 2018 Share Posted November 16, 2018 Easy, buy a drop in cartridge trigger group from the manufacturer of your choice dyi, cut the hammer spur off the existing hammer to lighten it, and use the jp yellow spring, and pay attention how the springs go on the hammer, it’s easy to put them on backward Link to comment Share on other sites More sharing options...
