It may, or may not live long or work with mil-surp and com-block. |

Toss the stock trigger in a parts box and install an ALG QMS. That's the only way I'd consider improving a stock trigger.

Spend the dough on a trigger. You will like it. Try the CMC 3.5 lb. single stage. Reasonably priced and pretty darn nice. I was always a stock trigger guy, then I put one of those in one of my AR's and really like it.

Agree on installing a CMC trigger. I was going to work on my mil-spec FCG and decided it was easier to go with the CMC and I am VERY VERY happy with the result. I got mine from Ares Armory for a good price and it dropped right in and feels incredible.

Just bought the flat bowed version of the 3.5lb CMC myself. Haven't gotten to really test it out yet though.

Thanks! That first link to the thread here on Arfcom is EXACTLY what I was searching for. Perfect....seeing as how a CMC is $150+.
I'm sure there are plenty of after market replacements that I'd love, but cruising\racing season is coming and the car is gonna demand all my fun money. Besides, since "the scare" is destroying the ammo market, I'm trying to stock up before the bottom falls out. :) Maybe if the FCG mods don't impress me, I'll try a new one. |

I also have a cmc 3.5lb flat blade trigger. It is awesome! Just went to the range today and was doing double tap drills. It is very quick.

It's real easy to fubar a standard trigger. there is a fine line between polishing the engagement surfaces and removing the hardened surface. I think that line is .03 milimeters but i could be wrong. i sometimes invert numbers in my memory. |

I hear ya EBH. I'm not going to go crazy or anything... I was basically just looking for some simple things to do to "clean up" the parts. Off-the-shelf products always have machining marks and rough edges. If I cut the hammer, I won't go as far as some...maybe 75% of that. There's always room for improvements without replacing parts. Kind of like porting an intake manifold for free instead of spending $900 on a new one that will accomplish the same thing.
Hell, if I screw it up, I just won't be able to afford putting the car on the dyno this Spring...I'll have to buy a new FCG instead.  |

Get some Remington 40X Bore Cleaner from Wal-Mart. It's a fine-grit abrasive suspended in a light oil. Use a few drops of it to lube the hammer-sear engagement surface, then dry-fire the gun 50-100 times. You'll notice a major improvement in the smoothness of the trigger, without removing too much material or hosing the engagement surface geometry.
Then clean the trigger thoroughly to remove all of the abrasive. Enjoy your much-improved trigger. |

I would never recommend altering a fire control group, especially if you have no experience doing it. Like a couple have suggested, just replace the existing trigger/hammer/disconnect with a new ALG ACT or ALG QMS. Both can be bought for under $70. I am using the ALG ACT on two of my ARs and I love it. It is smooth and breaks clean. Money well spent. ALG ACT ALG QMS |

Concur with the ALG triggers. Using ALG QMS triggers in 2 ARS and there are very nice. Then there is no need to worry about removing surface hardening by over polishing or anything...

I've combined the above triggers with JP springs and the set screw to yield a decent, budget trigger. Also have used the Daniel Defense trigger with the same "kit". An alternative to the 1/4-28 set screw is the sexier "Trigger Adjustment Screw". Not budget, but not a bank-breaker either...

Let me guess, you are one of those Oklahoma Street Racers, aren't you? You might even be Big Chief himself, lol!!!!!! So without taking this thread to far off topic, some of us are car/truck guys as well, so what are you wrenching on? As for triggers my next will be one of the ALG units, read good things about them and the price seems more than fair. YMMV?

Alright, alright... jeeez, I'll leave the FCG alone. For now. :)
I built a '69 Camaro for the 'road'. I lost interest in drag racing a long time ago, so I put this car together to have a lot more fun in for extended periods of time beyond 10 seconds. Little by little I've dumped a retirements worth of money into it but it's still a ways away from where it will ultimately end up. I drive it daily as well. Makes going to work actually something to look forward to. There's nothing like taking that on-ramp at 70mph at 6:30 in the morning, or standing on it and feeling 450 horses kick you in the back. Better than coffee. Donuts? Only if I'm not careful. |

I could not make up my mind - so I went QMS and like it very much. Not as nice as some of the 250.00 triggers I have used....but it is better than stock. My reason for wanting a trigger? Well, the one in there now (BS Special with 3-4,000 rounds) went full auto a couple of times - and since I have the M16 BCG - I don't need the man in my life. Also, since the kids use the gun often - it was not safe. |

I've decided it's not worth the effort to 'clean up' or work-in the stock trigger.
I spent some time on the range yesterday with my son after getting the new BCG. We spent around 300 rounds. I cannot stand the stock trigger. Y'all are right...it's not worth it. So thank you to everyone for spending my money for me. :) Gonna visit PSA at the end of the month and see what they have on the shelf. |

I have seen them for around $20 used snapped up fast that gives him the qms for $25 if he was worried about budget. I have seen $8 trigger gaurds sell quickly but with all that said I wouldn't waist my time either. Edit-The first thing posted on EE is a hammer spring for 10 shipped so he could technically get that QMS for next to nothing. |
