  1. Robert S

    Great price and great quality. Complete LRPK with 3.5lb drop in trigger for an affordable price. I will start using these on all my builds.

  2. Mark T.

    This kit is perfect for the guy wanting much better accuracy than a mil-spec trigger can provide. For the money everyone should just go this route. I’m glad I found out about this product.

  3. Gerald F

    If everyone knew about this quality of this kit, you would not be able to fill all the orders. I just ordered 2 more before the whole world finds out. Thanks for a quality product.

    Best lower parts kit on the market! The drop in trigger is excellent.

  5. Daniel Lerma

    Excellent quality super fast shipping trigger was better then expected smooth trigger pull and reset will definitely keep buying from you guys again can’t beat the price for the quality you get I have a pof flat trigger and honestly you can’t tell the difference

  6. Floyd Collier

    The Marksman lower parts kit comes with everything you need including an excellent trigger for a very reasonable price. I will use this kit for all my ARs from now on.

  7. Rick

    Assembled the lower today, everything went together smoothly. Trigger has a VERY nice feel to it. Raining today, so it will be another day to try it at the range

  8. Steve

    Super clean install and a crisp let off. Perfect drop in for the price. Glad that they are finally back in stock.

    I have to give this 4 stars as the kit had no instructions for putting it all together
