AR15 trigger work

[fatirerider]

I'm building a Mega lower w/ standard parts kit but the trigger pull sucks. Has anyone had luck reworking the mil. spec trigger, like shortening the sear engagement and changing the sear angle or does this greatly effect safety and reliablity. I've done this work before on 1911's and revolvers with great success but this is my first AR build and need a little input. I also have a full machine shop to work with. I'm planning on getting a match trigger in the future but until than.

Search for the "15 minute trigger job" in google and you'll find all sorts of sources.

My understanding is that the surface on AR triggers (carburized?) is very thin, making trigger jobs short lived. The Bushmaster DCM trigger on my rifle looks like it has a stock hammer, a trigger with the engagement surface replaced with what looks like a carbide insert and a safety with a strange setscrew and plunger arrangement to create a two stage pull and control overtravel. A skilled person could probably do it or something like it, but it might be better to spend money on the trigger and spend time on another part of the project, like a really cool looking muzzle device or handguards. Just my .02

I've done the "15 Minute Trigger Job" on several of my builds and it takes less than 15 minutes BUT.. it does work!!! I have fired hundreds of rounds out of my builds that have this 'trigger job' and have had no problems with any ammo I have fed through it going bang.... this includes GI LC ammo, my handloads with CCI primers as well as Federal primers and even Wolf ammo(YUCK)

As a side note.. my average trigger pull before the trigger job was averaging 8lbs.. with the 'trigger job', pull went down to a 5lb average. While not match quality, it is decent for a standard (mil-spec .. cough.. cough) trigger.....

Juan916, Thanks for the link.

Thanks for all the info. I'm a do it myself type ( love to tinker ). I think I'll just do some experimenting and see where it takes me. If you hear any fullauto bursts at the range it will probably be me testing my new trigger job.

I added the JP AR Reduced Power Spring Kit and polished my trigger and hammer to a nice shine, and slightly reduced the angles (do at your own risk!).

It's super crisp now with no creep. I've live fired and dry fired it about 150 times and it's doing well.

yeah, tell me about it. My original LPK didn't fit right under the selector, so after a little work, I got it in. Then my trigger pull was all weird and funky, so I "fixed it." Worked great after that......


Then a local LE guy comes in and says he needs a LPK ASAP for a shoot he needs to do. I say "you can borrow mine." But he needs HIS lower, so I just pull out my stuff and install it in his......... Well, suffice to say, he came back and said "what did you do to your trigger? I kept pulling off 3-5 round bursts...

I quickly put the parts back in mine and noticed the problem.... Over time, the sharp edge of the trigger rubbed away, and it would slip every now again. . . I trashed that kit, and bought a new one....
