Does anybody have a link for information on how to smooth out and lighten my ar trigger. What have you guys done in this regard. Thanks for any info.

Lots of posts/info about doing 15 minute trigger jobs and such. I wouldn't go mucking around with a stock trigger trying to make it into something that it isn't. A good quality trigger group that has a light, crisp pull attains that pull by virtue of the geometry of the mating surfaces and quality of the materials used. If you go hacking on a stock trigger, you run the risk of going through the hardened layer of the metal. If this happens, so bad things could happen, like it going full auto on you at a really bad time. Getting a stock trigger lighter also usually entails running light springs. Lighter springs do compromise reliability. I saw that someone suggested the JP 3.5lb springs. Stay away from those. I'd stick with the 4.5lb springs, at least.
If you want a better trigger, the best thing to do is to get a better trigger and not have to worry about whether the work that was done to the stock trigger will quit working. |

The 4.5 lb trigger springs are not recommended by JP for stock FCG. |

I've used the JP spring sets in several rifles without any issues. I also polish the engagement surfaces with a 1000 grit stone and lube them. Notice I said polish, you only need to make a few passes to remove any burrs. You don't want to remove the surface hardening. This works for me, its not the greatest trigger but is better than stock. |
| I know that they don't recommend them, but considering the number of misfires I've seen with the 3.5lb springs, I can't recommend those. I'm sure that the manufacturer of that stock trigger group would also recommend against trying to lighten to pull. I'm just trying to suggest something that will work without having to worry about things getting screwy. If you are going to go with a reduced weight spring kit, you might also want to consider bobbing your hammer. |
