This is my first build, and I read over and over that the trigger (and barrel) are very important. Yet, I broke one of those rules. I picked up a $30 PSA trigger then polished with 2000 grit until the machine marks just disappeared under magnification.
I've never shot an AR before, so I won't know if it feels junk or decent. In careful test fires (protecting the hammer with my hand), it feels alright to me. Thanks to this site, I have assembled a complete lower with one 30 round mag. CHAD |

You can clean up a GI trigger pretty good, but you have to be careful not to take off too much material and go through the hardened surface. I make "JP style" speed hammers out of GI hammers. We have an Instron hardness tester at work... So I have been testing the cutoff area, I have never found one under 53 RC. I think the story is false and the hammers are through hardened. |

| Triggers are like everything else from stereo speakers and motorcycle suspension to wine tasting. Some people can tell this or that but I usually just make do with what I can afford for a third hobby. If you're not competitive shooting you can deal with a lot more variation and/or upgrade it later. Spend your money on the barrel, that's something you can't DIY. |

Yup, they feel very similar. I have a couple of each, like them both but the PSA is half the price so its the clear winner for me. |

Yeah, it's pretty unlikely that only the top 0.005" of steel is hardened. Also, many triggers I've seen have the surfaces machined and/or polished at the factory after hardening. |

I think you made a mistake in "polishing" that trigger before you installed it. You had no idea whether or not those marks you got rid of were doing anything, and you risked "polishing" away much of the case hardened surface of the parts you messed with.
MOST stock triggers are "OK" if you install them correctly. FIRST AND MOST IMPORTANT, you must clean the parts before you install them. Manufacturers don't lubricate parts when they ship them, they protect them with a coating that sucks as a gun lube. Once you've cleaned that stuff off the parts, install them carefully. Put a dab of a good, light grease in the trigger pin and hammer pin bores before you install the pins, and of course make sure the springs are installed correctly. Finally, LUBE THE CRAP OUT OF THE PARTS. Most of the heavy, gritty feel people complain about with stock AR triggers comes from the parts not sliding on their pins, so that little bit of grease fixes that, and lubing the parts generously keeps them moving smoothly. Now, since you've never fired an AR, you're in a pickle. You won't know if that polished trigger "feels" off or not, you won't know if you really got anything out of your efforts in working on the parts, and you may have screwed them up in the process. I STRONGLY suggest you buy a new FCG - like maybe PSA's nice pre-polished and coated FCG - and consider your polishing job and its results part of the cost of learning the AR. Cheers. |
