It depends on the model.
A two stage trigger has a take up pull then stops, at that point further pressure on the trigger causes it to fire. M14 and M1a, pretty much all gas guns, require a greater trigger pull then bolt guns due to the fact that they automatically reload once fired. Instead of having a 4 - 5 pound pull trigger the designer splits that in two using a 2 stage trigger.
Type your answer here... how do I adjust the trigger on Remington 799
No, the Gyphon does not have an adjustable trigger
It is very easy to adjust the trigger on a Model 700 Remington. Remove the rifle from the stock and there is 3 small screws you can adjust. One is for the lbs. of trigger pull, which be careful you don't make it so easy it's a hair trigger and could go off just by the jar from closing the bolt. The other is to adjust the length of trigger pull.
The only way is to replace the whole trigger but it will still have a hair trigger
On "Rimfire chat" I read the following.. If you "flip the sear spring" the trigger pull will change from about 5 lb's down to about 2 lb's.
You take it to a gunsmith
It can be sent to the factory for adjustment.
It depends on which marker you have and which trigger is on it. Typically the manual will tell you how to adjust it
First a single stage trigger. A single stage is the common type of trigger where you pull quite a ways until, at some point, the gun fires. A two-stage trigger eliminates that ambigious "some point" by adding a second stage to the pull. Basically, the trigger "catches" for lack of a better term (really it doesn't catch, it just encounters a greater resistance) towards the end of the pull. When you feel that resistance, you know that the next little bit of pull will fire the gun. One advantage of a two-stage trigger is that if you want a heavy trigger pull (like you would want for safety in law enforcement) it allows for this force to be broken up in two stages of the pull. This helps accuracy. For instance, with a 5 pound pull, you can put 3 pounds on the first stage and 2 on the second. You can aim, pull to the end of the first stage, then exhale, gently squeeze and BANG! Good fun, just like Iron City Blues.
You find a Browning trained armorer
Best left to a trained gunsmith.
