    I made the mistake of going cheap on my LPK when I built my AR. It is the only thing I am not satisfied with so I would like to do a little upgrading. I originally bought mine from AIM surplus simply because it was stainless and I wanted the contrast on my gun. I did not think about it being heavy through the entire squeeze like a double action revolver. I would like to find something with a lighter pull and possibly two stage, but I don't really know what to be looking for. I know there are the high dollar drop ins like a Timney, but I don't know that I need the whole breaks like glass competition job. I want to know from some of your personal experiences where I could find a better LPK or just a new trigger and springs so I don't have to buy the whole kit. Thank you

    I checked out the Geiselle and they are nice but a little pricey for me. I want something that will improve on what I have but I dont know if I need something of that caliber. Is there another brand that may be a little easier on the wallet?

    The rock river 2 stage should be about 80-$90. I'm happy with mine.

    Wait, Geissele is making a modified milspec type single stage trigger for $45 & $65.

    Should be out soon. In the mean time get a JP trigger and hammerbspring to lighten up ur pull, iirc $15.

    I used a Rock River Arms LPK with a standard single stage trigger recently and am really happy with it. The contact surfaces on the trigger and hammer were all highly polished and the trigger pull is smooth as silk. There is no slack in the trigger or over-travel that I can detect. The rest of the parts all went in perfectly without any issues. Two-stage triggers have their place in the world, but for me the single stage is more like what I wanted.

    Here's the LPK I used:

    Here's the two-stage RRA LPK if you are interested:

    The ALG Defense Quality Mil-Spec (QMS) Trigger is designed for those shooters where tradition, value and regulatory
    concerns are of primary importance. The pull of the QMS is very similar to a standard mil-spec trigger, however the
    majority of the associated grittiness of the stock trigger pull has been removed while the well known reliability of a stock
    trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs

    1. Performance Advantages for the Shooter
    • The ALG Defense QMS trigger pull is smoother than a
    stock trigger. This is accomplished by honing the sear
    surfaces smooth while not removing metal below the
    valleys of the stock surface finish.
    • Sear geometry has not been changed from
    standard so the high reliability that the stock trigger is
    known for is unchanged.
    • Trigger and hammer are made from true 8620 alloy
    steel military specification castings, correctly carburized,
    quenched and tempered for high surface hardness.
    • Disconnector is 1070 High Carbon steel properly
    Austempered into the spring range of hardness
    • Springs are corrosion resistant and meet military
    specifications.
    • A full force hammer spring is used for positive ignition
    of all type of ammunition.
    • Trigger and hammer pins are improved over stock mild
    steel by using 4140 Chrome-Moly steel that has been
    quenched and tempered. Pins are centerless ground to
    a fine finish and a diameter 0.001” larger than stock to
    reduce play in the trigger assembly while retaining a slip fit
    into the weapon lower receiver.
    • Pull weight is above the U.S. Military minimum pull
    weight of 5.5lbs but does not reach near the upper limit of
    9.5lbs. Generally, the pull weight is about 6.5lbs


    2. Advantages for the Armorer
    • The ALG Defense QMS trigger is an enhanced
    standard trigger so maintenance and installation procedures
    are unchanged.
    • There is spare parts commonality between the QMS
    and stock triggers
    • Trigger assembly parts may be interchanged between
    triggers, there are no matched sets.
    • Since it is a trigger meeting the U.S. Military trigger
    specifications for the M4 Carbine, the ALG Defense QMS
    can be substituted for lower performing stock triggers while
    still staying in compliance with Unit or Departmental
    requirements.
    Retail Price: $45

    The ALG Defense ALG Combat Trigger (ACT) is designed for those shooters where tradition, value and regulatory concerns
    are of primary importance. The pull of the ACT is very similar to a standard mil-spec trigger, however it is sharper and the
    grittiness of the stock trigger pull has been removed while the traditional reliability of a stock trigger remains. The pull weight
    is not lower than the M4/M16 minimum weight specification of 5.5lbs


    1. Performance Advantages for the Shooter
    • The ALG Defense ACT trigger pull is smoother and
    sharper than a stock trigger. This is accomplished by
    polishing the sear surfaces smooth and HardLubing the
    trigger components.
    • Sear geometry has not been changed from the
    standard profile so the high reliability that the stock trigger
    is known for is unchanged.
    • Trigger and hammer are made from true 8620 alloy
    steel military specification castings, correctly carburized,
    quenched and tempered for high surface hardness.
    • Disconnector is 1070 High Carbon steel properly
    Austempered into the spring range of hardness.
    • Springs are corrosion resistant and meet military
    specifications.
    • A full force hammer spring is used for positive ignition
    of all type of ammunition.
    • Trigger and hammer pins are improved over stock mild
    steel by using 4140 Chrome-Moly steel that has been
    quenched and tempered. Pins are centerless ground to
    a fine finish and a diameter 0.001” larger than stock to
    reduce play in the trigger assembly while retaining a slip fit
    into the weapon lower receiver. Both pins are Nickel-Teflon
    coated.
    • Pull weight is above the U.S. Military minimum pull
    weight of 5.5lbs but does not reach near the upper limit of
    9.5lbs. Generally, the pull weight is about 6.0lbs.


    2. Advantages for the Armorer
    • The ALG Defense ACT trigger is an enhanced
    standard trigger so maintenance and installation procedures
    are unchanged.
    • Trigger assembly parts may be interchanged between
    triggers, there are no matched sets.
    • As a trigger meeting the essential U.S. Military
    trigger specifications for the M4 Carbine, the ALG Defense
    ACT can be substituted for lower performing stock triggers
    while still staying in compliance with Unit or Departmental
    requirements.
    Note about HardLubing:
    HardLubing is ALG's term for electroless Nickel plating with
    an integral modifier to the base nickel plate. Either Boron
    or Teflon is used to enhance surface hardness, wear
    resistance and corrosion resistance and also create
    favorable tribological properties of the trigger components.
    Testing has shown that differential coating of the
    trigger parts contributes to the sharpness of the ACT's
    single stage pull. The trigger component is plated with
    Nickel-Boron which has a high surface hardness combined
    with excellent wear resistance. The color is a pleasing
    matte light grey that may be painted on non-functional
    surfaces if the shooter so desires (such as the trigger bow
    that is visible outside the lower receiver). The hammer,
    disconnector and trigger/hammer pins are plated with
    Nickel-Teflon which combines a low coefficient of friction
    with good wear resistance. The Teflon impregnation colors
    the metal a mottled, greyish/green. Parts coated with
    Nickel-Teflon cannot be painted. Both coatings are highly
    corrosion resistant eliminating the oil seal of traditional
    phosphated firearm components.
    Retail Price: $65

    BTW a single stage milspec type trigger is a great all around choice for multipurpose use. For me, a smooth single stage is good for shooting inside of 200 yards. If I want to go out further I usually look for something else.

    Two stage are better suited for precision type builds, as the second stage allows you to know exactly when the trigger breaks.

    Figure out your intended use, and let it guide your decision.

    I think that's good advice. Pretty much everything I do now is inside 100 yards and a crisp milspec trigger is all I need.

    Link please?

    I have an unfinished lower and a lower with a standard DPMS trigger I would like to trade out.

    I have yet to see a RRA under $125.00. I did purchase a complete RRA LPK for $150.00 a year or so ago.

    'The RRA 2 stage is a good trigger and one I recommended to you in pm. You can try cheaper still by getting JP reduced power springs, link and video tutorials provided. There may be issues with redcued strikes on primers - I've never run into it, but there are always people who wil sya they "heard....
