AR-10

pigfarmer05
I was wondering if anyone knows what an Armalite AR-10 with a CKA lower receiver is worth. I believe it is either a portuguese or guatumalin style.

    I don't know what type of trigger the standard DPMS uses, I have a POF with DPMS upper and use a plain old RRA 2 stage trigger. There are ways to tweak the standard AR trigger by stoning and tweaking the trigger reset spring, but for about $90.00 the RRA 2 stage is very good: http://www.ar15sales.com/index.htm

    I am with Dfletcher on this one. I would just change out the trigger for a two stage trigger system, and that way you retain the all original.

    I prefer the Bushmaster adjustable two stage trigger. I have become a master to adjusting and tweaking it.

    EDIT 1

    I was just looking thru your first post, and noticed this
    quote:It still jerks to the right 3-4 inches at 50 yards.

    That is part of the problem...you are jerking and flinching. No matter what you put in it for a trigger, it is not going to fix it, unless you fix yourself first. Don't jerk the trigger, anticipating recoil, as the rifle will recoil even if you anticipate it. That is what develops the flinch. I have vast expeerience in this matter of my own. That can be fixed by humiliation...that is in front of peers, have someone load the gun for you with 3 rounds...two being live, and one a snap cap. When the gun goes click and you jump out of your shoes, and are embarrassed, you learn to control that...especially from a rifle that has minimal recoil. Once again, my own experience. Try it, and keep going untill you are not flinching.

    I would tell you too look into a new trigger as well, but that doesnt mean you cannot also change the stock for one with more adjustment and more comfort to use.

    all you have to do is buy a carbine buffer tube (receiver extension) with castle nut and plate the buffer and spring need to be AR-10 carbine specific.. If you do buy a carbine extension the buffer and spring need to be AR-10 specific. Carbine receiver extensions come in two diameters, the just of it is commercial reciever extensions are larger in DIA then the other type, Mil spec receiver extensions.. Once you choose a reciever extension the stock needs to match its diameter..

    DPMS AP4 carbine reciver extension and hardware. it is commercial diameter

    My advice is to look into a retractable stock with an internal tension locking mechanism, or the magpul UBR or M-93b.

    Also you can add an ACE LTD aftermarket stock to the reciever extension on your rifle (if it has an A2 stock), they come with rubber buttpads and have a foam rap around check piece.. if the length of pull is not an issue with the A2 length stock, they are nice.

    you can find instruction videos on the net to help you install either stock, or have a gunsmith do the job..

    3 or 4 pounds would be my personal preference.. I would tell you to look into an AR-10 specific Geissele automatics trigger..

    If you're pulling then you're pulling. If you need a lighter trigger you can do that easily with some lapping compound, a pin punch, and some instruction.

    The "15 minute trigger job"

    If the stock fits you before you fire it probably isn't the stock.

    Also, I would suggest looking into a muzzle brake.

    Beyond those, I would say focus on your shooting fundamentals.

    Added:

    Here is another accessory that comes in handy. It replaces the screw holding the pistol grip on. It in turn has a screw up through the center of it that stops the sears rearward travel. The point in this part is it takes up slack in the movement of the sear so you don't have as much take-up to trip the trigger.

    Please mail payment of check or money order for $20 per adjuster to

    You have to be very careful with lapping compound, alot of triggers are only surface heat treated, by useing lapping compound incorrectly the FCG can wear in the wrong places and lead to a runaway rifle, the ATF always frowns on that, not matter the excuse.so if you are at a public range, or have a nosey neighbor they might call the cops first and ask questions later.[:)]

    Yes, that's why in the instructions it says to only cycle that through about ten or fifteen times then clean it well. Do NOT go back and redo it later. Put some oil or grease on it and cycle until smooth if it gets rough again. What has happened is either the lube you had on there dried or surface corrosion (rust) has made it rough.

    As for going full auto on you. You have more potential of a full auto incident if you have a bad adjustment between the disconnect arm and the hammer. Do NOT try to smooth anything out between the hammer and the disconnect arm. That is the most prominent cause of a rifle going full auto.

    I say this because even if the sear won't re-engage the hammer, the disconnect arm does if you keep the trigger pulled back after each shot like you are supposed to.
