    I am just wondering if there is any advantage to buying a select fire trigger vs. a 2 stage. If I have a semi auto ar15. If I put a full auto safety would that allow me to have the best of both worlds meaning a standard and a 2 stage trigger?

    Full auto triggers are the same as semi auto triggers. The differences in the trigger group are the safety, hammer and full auto sear with attendant pin spring and sear hole in the reciever.

    While it is technically legal to possess a full auto safety and hammer there is no ruling from the batfe that they wont prosecute you for putting them unmodified to semi only in a semi auto reciever.

    Full auto parts in a semi auto configured lower offer no advantage or use. There is no reason to run the risk of the issue ever coming up in court if your rifle is ever taken as evidence in a self defense shoot or action.

    While fa bolt carriers have a blanket approval by the batfe other fa parts do not and its beat to avoid them.

    Do you really want eric holder and barack deciding your fate??

    Are you sure that you are talking about a select fire trigger? As in a trigger that will let you select between, semi-auto, burst, or full auto?

    Thank you my question was if there is any advantage to having full auto parts in a semi auto rifle for example could you flip between single and two stage trigger pull. If there is no advantage then I wouldn't bother.

    Yes it wont fit without major modification to the lower so dont waste your time :D .
    I think your a bit confused , a single stage trigger there is little to no take up and then bang , a 2 stage has alot of take up and then it stops , light pull and bang
    You either get a single stage or a 2 stage there is not a trigger that will toggle between the 2 that I know of.
    Hope that helps

    I suppose a FCG and selector could be designed to give you a single action/double action trigger depending where the selector is pointed (90 or 180 degrees). But if something goes wrong and you actually get full auto... oopsie, Mr ATF agent man!

    A two stage trigger is ideal for general defensive offensive use. It makes it a LOT harder to ND into your buddies or yourself while your under stress or while wearing gloves.

    Single stage are great for competition where your life isnt on the line and you need that edge for game competition.

    They serve different purposes and the guns that use them really dont translate well from one role to the other.

    Dammit guys now I'm really confused. I was on a different thread talking about my 2 stage trigger and someone pointed out it wasn't. When I checked on Brownells site it was listed as single stage. It is an ALG ACT. It has a short amount of light smooth take up then stops and breaks smoothly. My AR rifle with stock parts does the same thing only heavier, not so smooth and a heavier break. The S&W Sport has almost no take up and a break between stock and the ALG. My last trigger is a Wilson Combat TTU M2 in a 308 it has a short super light take up and bolt action like break...A good bolt that is. Aren't all of these single stage and a two stage a different design all together? One that has two separate points of contact with the difference between it and a set trigger being that the set trigger stays set and a two stage will reset if released?

    Well it sounds like you're describing 2 stage in your Wilson Combat while the others are single stage. Most ARs come with single stage milspec triggers. The ALG is a cleaned up milspec single stage.

    Quentin, The Wilson blurb calls it a semi two stage and it is a module so I really haven't got a good look inside. I bought the ALG from a buddy who traded his Bushy for a Colt while it was in route. It is "THE" trigger along with a JP spring set that I would put in an AR that is liable to be held in a stress situation. The .308 was put together to be kind of a precision carbine, still on the fence as to how that is gonna work out. Had one of Sams M16s in the early 70s, didn't like it. Got my first at about age 50, now have four and have a lot to learn. It's the damn kids I hang around with that got me started.

    Its a two stage regardless of what the claim is. A true single stage has zero, absolutely no take up. If the trigger moves even a scootch before contacting the sear its a two stage.

    Set triggers like you find on a lot of cz rifles (absolutely outstanding triggers btw) can be run as a normal two stage or as a one stage by pushing the trigger forward it turns into a glass rod breaking feel several ounce single stage trigger.

    Correct me if I am wrong. The standard AR trigger is a single stage with a 7ish LB pull as issued to various military and government agencies and LE agencies. Correct?

    It's always been my understanding a heavy single stage trigger is what you would want in a self defense situation. I see the logic to your statement, my m14 has a long heavy double stage trigger but it is very soft trigger at the same time.

    Standard ar15 triggers are two stage. Weight of pull or presence of trigger creep has nothing to do with with wether a trigger is two or one or set.

    All military triggers are two stage. What your experiencing on your M1A is creep in the second stage. Two stage triggers have spring tension that keeps the trigger from contacting the sear. This means that while your bouncing around in a vehicle, running, hitting the dirt, or other actions like that jarring the rifle wont accidentally fire a round.

    Single stage triggers the trigger is in constant contact with the sear. Its why you see trigger safeties on lots of rifles becoming the norm. It gives the superb feel and control of a single stage with the safety of a two stage. Examples are the superb savage accutriggers which are safe for hunting and field use.
