    So I just got done assembling most of the lower on my first ar build. I was testing out the trigger, hammer and sear to make sure everything was functioning correctly but noticed that as I'm squeezing the trigger back while the hammer is engaged if feels gritty. Now I'm a machinist by trade (not a machine operator) and know that no matter how good the finish looks there are always going to be some mill marks. Just wondering if this is normal. Incase it matters any it is a daniel defense lpk in a psa lower. Thanks for your help.

    It's common for a milspec trigger to be gritty. It can improve over time but don't expect a real smooth trigger at milspec cost.

    Its pretty heavy also is that pretty standard of a mil-spec trigger? I guess I might have to upgrade. But why the extra cost then?

    Mil.spec.triggers seem to vary a lot I have purchased 9 of them from PSA and out of 9 only one was what I would call terrible. Sand like gritty feel. The rest have been fabulous and the most recent one was as good or better than my favorite reworked trigger and this one was straight out of the bag.
    My brother in-law just had to buy a Daniel defense lower parts kit and it was real gritty also. However DD is going to send him another one. They said it should not have been like that. I guess we will see when it shows up

    Maybe ill try to get ahold of them and see if they will send another one. I have been shooting for awhile now but this is my first ar. To be honest this is the worst trigger I have ever felt. I didnt think it would be quite this bad. Thanks for your help guys ill get in contact with dd and see if they can help me out.

    What extra cost? The cost of a DD LPK over an el crapo kit? :confused:

    When you buy a milspec trigger you can't expect one that breaks like a glass rod. No matter what brand. If you get a real good one that's great but most are just average.

    If something's really wrong, are you sure the springs are in right?

    Yeah the dd kit costs $35 more than say like a dpms kit. From what I can tell the springs are in correctly. Everything looks exactly like the pictures in the book I got. I followed those directions word for word. I'm not sure it might be that I'm not used to a run of the mill mil-spec trigger. None of my guns have stock trigger they all are atleast cleaned up and smoothed up. Ill have my smith check it out before I do any shooting

    Well you might look at the sear areas and see if there's a gouge or something unusal. Barring that I'm not sure if they'll replace the trigger unless it doubles or malfunctions somehow. Guess you'll find out when you talk to them.

    One thing you can try is removing and cleaning off your fcg real good, and put some good grease on the sear sufaces and where the pins go. Also a little dry firing should help smooth things out, just dont let the hammer hit the reciever if you dont have your upper and bcg on. Taping a couple cotton balls or an old ear plug will soften the blow. I know holding the hammer back with your off hand gets old after a while.

    Before paying anyone for a trigger job, id recommend looking into an ALG trigger. The price of a qms is cheaper than what most peopl chagrge for a trigger job.

    Honestly i think ALG should just sell lpks, they sell hotter than psa kits.

    Ill take it all apart and clean it up good again and grease it. I didn't do that before I oiled it well but no grease. Ill look into the alg trigger group. I wouldn't pay to get a trigger job done on this trigger its just not worth it when I buy a real nice trigger for the same price. I'm going to use this gun for hog hunting so I would like a 2 stage trigger. Does anyone have any good places to start looking for a pretty nice 2 stage that won't break the bank?

    Is there a noticeable difference if feel between the ACT and QMS?

    From reading the ALG website it seems like the ACT is just polished a little more and nickel-boron / Teflon coated.

    Well since I won't hunt with such a crap trigger like the dd one I have now, are there any other ones worth looking at besides the alg? I have heard a lot of good about the rra national match 2 stage are they any good or just hype? I know some of the bigger names get a cult following sometimes and people think they can do no wrong. But seeing as I'm new to the ar world I figure it can't hurt to ask before I spend a small fortune

    Do you have access to other ARs with milspec triggers to compare to yours?

    I've used 2 DD LPKs which both had good triggers. Also 3 Stags (2 good, 1 pretty bad). A Bushmaster was pretty good and a DPMS was awful. Really it's luck of the draw and some milspecs are just as good as the ACT and QMS. The nice thing about the latter two is they should be better than a crappy milspec.

    Any luck with DD CS?

    There is a difference. The ACT is slightly lighter....greased...um how do I describe it. Buttery! I can feel the difference. My wife cannot. But she's not really an avid shooter.

    In my personal opinion. I don't think the ACT is worth the almost 50% increase in price. I believe that if the QMS were standard issue, most people would not even feel the need for an aftermarket trigger. Its what every run of the mill milspec trigger should be.

    I am reserving my ACT tho for possible future build with a 5.45 upper. Them corrosive primers can be nasty. ;)

    I didn't get a chance to get ahold of dd cs yet. It was a crazy day. I will get ahold of them tomorrow though. But I can always get ahold of my buddy that works at the lgs and go compare triggers he's done a bunch of builds with all sorts of triggers.I'm not looking for the greatest trigger in the world I just am not looking for a gritty pos. Something consistent the one I have now creeps a little different everytime because there is no smoothness to it at all. Hopefully dd cs will send a new one but if they won't ill just get a nice 2 stage

    If your buddy goes through a lot of triggers maybe you can work out some arrangement with him to trade you a better milspec. Otherwise Agent Tikki's advice on the QMS might be the way to go unless a decent milspec isn't enough.

    I went through about 7 LPKs over the last few years to end up with good triggers for 4 ARs. I kept one LPK with a decent trigger as a spare and sold the other two at a fair price. I'm satisfied now since a good milspec is fine with me.

    Ok so just got off the phone with dd cs and they said to try to grease it good and break it in. If it isn't any better after a 10 or 20 rounds he said call back and they will send me a whole new lpk. He said it was no problem and they had a few guys in the last month call with the same problem. Must have been a sub par batch or something. I'm very happy that dd will stand behind their product and do their best to get the problem resolved. Ill definatly order from them again.

    And as far as my buddy trading he will never go for it he is a freak about his ar's just like the rest of us and he likes all the ones he has. It never hurts to try though. Thanks for all the help guys.

    66,

    I will cut to the chase! Go get you a Rock River Arms 2 Stage National Match Trigger and just drop it in. You should be able to find one at a gun show for $100 or less if you shop around. Retail I think is about $125? You will be impressed I assure you! And then later if you even want to make it better, get a set of KNS Anti Rotate Trigger and Hammer Pin Set. Not real expensive either. And what a difference they will make. I have them in my Sabre Defence 6.5 Grendel and a great improvement! And then set back and Enjoy!
