  1. Hugh Evans

    Great lowers if you want to build a complete bcm rifle or even great if you not comfortable building your own lower at the moment

  2. Rusty Shackleford

    Great lowers. I have had a few of the blem and non blem bcm lowers for years now. They are well made and perfect for combining an upper with to save money and still have a really nice ar15.
