    Liberator polymer 80% lower

    Some fitment issues. I did a great job with milling but I screwed up when trying to mill to make breakdown front fit better.

    Super Easy

    I used a mill to machine out the trigger area. And it was easy. Did it on my lunch break. The take down pin and pivot pin are a little tight but that’s okay. Makes for zero slop between the upper and lower. Ran 500 rounds through it without a single hiccup. I’m pretty happy with this.

    liberator 80% lower

    Posted by gray on 13th Dec 2019

    this item was received on time and looks good, especially like the metal inserts, the sides on the one I received seem to be sunken in a little bit and are not perfectly flat so I don't know how this is going to assemble but I guess we'll see, otherwise nice receiver.

    It didn't quite fit..

    Posted by James on 28th Jun 2019

    I have a PSA and an LMT upper, neither of which fit this lower receiver as the buffer tube mounting point was too thick. I haven't had any issues with other lowers mating to these uppers. I'll have to sand it down to remove about a quarter to half inch of extra material that is preventing me from using this lower.

    It was otherwise a very simple operation to use the jig and much more pleasant than machining aluminum.

    Great product

    Quality lower that's easy to mill. This lower has been very durable.
    For best results mill close and finish off with a file.
