AR-15 trigger job

Yesterday I handled an AR-15 that had the best trigger that I had ever felt on one. It was at a pawn shop and it didn't have a "trigger pack", it looked like a normal trigger. That got me researching trigger jobs that you can do yourself. This one had almost no crepe and was light. I would have bought it but they wanted a post school shooting price of $800 for a Plain Jane Bushmaster, so I passed. Have any of you guys done a polish and hand guard set screw set up on yours? If you have how were the results? I'm thinking of doing it to one of mine.

its not worth messing with, go to far and you have to replace the components, get an ALG and be done

ALG Defense was founded by William Geissele’s wife, enough said , they just clean up standard mil-spec triggers at 1/4 the cost of a Geissele

I have them in all my ARs.

I cant imagine a $200+ trigger being $200 better than that.

Get the adjustable grip screw, and prepare to be amazed for about $75.00

DO you guys use the ACT or QMS?

I believe it’s the ACT and I agree to they are really great triggers

The ACT is the better of the two, mine have been good but my $100 Larue mbt trigger is far nicer if you spend just a bit more.

Also recommend the Laurie MBT. I have a few of them now and they are just as good as my Geisselle which was 2x the price.
Still on sale for $99

I've done a few, the screw up the grip cost me $.50 (menards) a bit of emory paper costs $2 or $3.... The springs are the springs... cut a bit off the hammer spring (one side) and it its nicer, but to reduce the pull, ya gotta get a lighter trigger spring... the key here is to take your time, if you rush it, you can ruin things... I got hasty on the set-screw up the grip, altered the safety too much, and ruined it.... The $13 0r $15 dollar gizmo they sell on the net is more of a deal...( grip screw with a adj. screw within..) The cutting of the hammer spring sometimes raises issues with ammo that has 'hard' primers. On youtube, I seen a 'rope-trick' that seems interesting.... it sounds like it does what emery paper does.. sorta.... bottom line is take your time, use common sense, and ( did I mention ) take your time...

I did the set screw thing with y daughter's AR. The gun is now doubling. I have not shot it myself so it my just be that she's not holding her mouth right.

I have tried reducing the sear engagement. My experience has been that the corner of the trigger peens over and round out. Again double fires. Sear/trigger contact points were not touched.

My best trigger is a Jewell. It matches it's name. Two stage, fully adjustable. My first stage is at 2#, second at 1# for 3# total. Pricey but I'm worth it! [smilie=011.gif]

I know this isn't what you intended to type but I'm sure dirty minds are wondering

Seems like a lot of you guys like two stage triggers. Not sure if I want to go the two stage route.

I get good results just using a cloth wheel + polishing compound to slick up the interface between the hammer and trigger. You do NOT want to remove any metal or change any angles, just get those engagement surfaces all slicked up.

Haven't tried the set screw yet because I haven't felt the need, but I can see where that would help.

I would not trim the hammer spring for the very reasons mentioned above.

Before reading this thread I was looking at a Rock River Arms trigger. Same price as the ALG. Anyone use a RRA? Does the ALG use a lesser power trigger spring?

I prefer single stage triggers myself, and have put in a (used) Timiny in one AR, which was great, and a Velocity, which is good. I wish I'd kept the Timiny for my other AR.

I have also polished a regular trigger group for use, and they are alright. There are a lot of just under $100 drop ins that I'd like to try; RRAs has a good rep, but I think they are all two stagers.

I just ordered an ACT for the A2 I just put together. It beats the hell out of all the polishing and the risk of fouling up a trigger group as you stated ( I will admit I did ruin a TG back in the 1990s by rushing thru it when I was into ARs [-X ).
After I receive mine I'll give a range report regarding its quality and performance.

Thanks for the advice.

I just ordered a POF trigger, got it used for $85. I have 3 Colt AR's and I'm used to the regular trigger I;ll see how it goes with a 3.5 lb one.

I've put RRA two-stage triggers in all my ARs - I like the similarity between them and my M-14s & M1s.
