Changing Trigger in AR

[txhoghunter]

So I have been looking through a post about aftermarket triggers being run in people's ARs and I have been wanting to get away from the stock trigger in mine. My question is not what trigger to get but rather how easy it is to install a new trigger? Is it something that I can do (will a moderate amount of gunsmithing experience) or should I let a reputable gunsmith do the installation?

Very easy to do...if you get a "drop in" after-market trigger.

This assumes your lower receiver is drilled correctly (specs) for the trigger group. Occasionally... someone will experience interference with their safety and some slight mods are necessary.

Depending upon what you use your rifle for, a non-adjustable trigger (either single or two-stage) should be easy to install and give you no trouble.

If you need/want an adjustable trigger...then you need to know what you are doing when setting it up (for safety sake).

if you are doing a drop in kit- like a 2 stage bushmaster or any reputable manufacture's kit, you need only a small punch and a few minutes of your time. The triggers on an AR15 are very simple to change out with a parts swap. As flintknapper mentioned, if you want to get super fancy, you need to know a bit more.

No gunsmithing experience here but I swapped out my trigger for a Geissele 2-stage (non-adjustable) and had no trouble at all. Only issue I could see is if the receiver, safety, or some other part was out of spec and required further modifications.

Takes me about ten minutes. Five of them is aligning the hammer pin since the spring puts a heck of a lot of tension and makes it all difficult.

It's eight parts: hammer pin, trigger pin, hammer, trigger, disconnector, hammer spring, trigger spring, and disconnector spring.
