Something I have always wondered about the AR platform, is the variety of triggers. There are a ton, ranging from 50 bucks to a few hundred. Now, I plan to pick up a Gisselle SD3G for my new build, but what really is the difference? I've looked at all of them, and they all nearly look the same, basically, the only difference being the contact point.
Could a good smith take that trigger from a basic lower parts kit and make it perform like a high end trigger buy simply changing the geometry or polishing everything really well? Just always been curious about. |
| Not really, Geissele triggers are a different design than your standard military trigger. There have been several different kits to improve the stock trigger over the years, mostly via springs, but replacement is likely the better, more reliable option for a lighter pull. If you're looking for a match like combat trigger, the Geissele SSA is very common, while the SD3G is more of a fast trigger for 3 gun competition. |

I think you are incorrect by saying that they all look alike... The two main types, single stage and two stage, are VERY different looking. Also, a lot of higher end single stage triggers have a hammer that is very different from the mil spec single stage hammer. And so on. But why should what something looks like matter? Who cares? It's about function. Some triggers function better, and I couldn't give a rat's ass if it looks like every other trigger.
And yes, some gun smiths can clean up a trigger, typically a mil spec trigger, but there an be issues there as well. Sometimes the sear is surface hardened, so if you take a file to that, you rub off the hardened metal and get down to the softer metal... The trigger may not last as long now and more importantly, it may be unsafe. |

Thats why im looking at the Gisselle since i know its really high end and they have a great reputation. I have a Timney in another AR build and occasionally have issues with it. to the poster above you, you mentioned the SSD, what is the difference between that and the SD3G? Their website isnt very clear on it, unless there is a better source that really details them. |

All standard FCG’s should be hardened, however the hardening is in the surface with little depth to it.
The SSA is not a match trigger, but all the ones I have are far superior to the original FCG’s. They are non-adjustable so there are no adjustments to come loose. They are also known for a long service life and reliably firing all kinds of ammo. |

From the pictures of the Geissele SSA trigger, it looks an awful lot like the M1 Garand/M14 design, which is an outstanding design. I have one and I love it. My BCM Recce-16 SS410 Precision came with a ALG ACT and while it's better than a standard mil-spec, it's nowhere near as smooth as the SSA that I swapped in  .
