Today with about four decades behind the M-16/AR-15 development, this weapon has turned into an accurate gunning system largely due to CNC machining, improved design, better fitting receivers, and barrels. Even so, bad triggers produce bad results down range.
in case you're just not pleased with the results you're getting with the factory installed trigger, here are some suggestions for replacing your stock trigger with one of the best AR-15 triggers on the market.

7 Best AR 15 Triggers
1. Timney USA - Best AR Trigger
For a quality, American made AR trigger you can't go wrong by turning to the folks at Timney Triggers. Timney has a plant in Arizona that is state of the art.
I know this because I have spent a couple of days going through the operation. I observed every level of development, testing and manufacturing that the company does.
When a Timney trigger hits the assembly clean room, every element of care is taken to ensure the production of the best trigger possible.
Any error in measurement means the part is off the line. I never saw an issue with anything being brought together in terms of rifle triggers when I visited the facility.
The Timney AR-15 trigger is a self-contained module. This drop in trigger installs as one trigger module not a bunch of springs and parts that require five hands and two men to put together in the AR's receiver. This trigger module is ready to install. All you have to do is place it in your AR-15.
This is a single stage trigger, meaning that it has one length of trigger pull as it drops the sear thereby releasing the hammer. The triggers are all hands on tested and weight measured prior to being packed for shipment to stores or individuals.
When a Timney trigger is installed in your AR-15, the feel is like a bolt gun instead of the common crank effect on some basic combat model M-16/AR-15's.
The guts of the Timney is an all aluminum housing and a hammer machined of high-grade S7 tool steel. This trigger is built to hang together under very heavy use.
This part is heat treated at an RC of 56/60. The trigger installs using your own factory hammer and trigger pins for fast but accurate placement within the lower receiver.
Poly receivers (lower receivers) require a special install plate that Timney can supply.

Hiperfire is a brand that I have come to know quite well. Coming out of Minnesota, my old home base, the company has allowed me to spend some time at live fire demos.
I yanked some triggers on the military based products day at Boulder, NV just prior to the Great American Shot Show.
Hiperfire turns out all the toys for big boys and then lets the fun begin.
Offering a complete range of triggers from competition to combat based systems, the company is a class act in terms of building some great AR-15 platform aftermarket trigger systems.

This trigger retains no take-up/pre-travel, maintains a very hard hitting hammer, and features a soft start lock-up TM (for preignition stability). The trigger weights run from 2 ½ to 3 ½ pounds.
