    The kit was great and exactly what I needed. I have just gotten into making my own AR’s so this worked perfectly for me. Price and quality was great! Thank you!

    Lower parts worked just fine

    Shipping was a bit long but I understand what the country is dealing with so that was ok but the parts were all there and I’m separate packages and that helped with assembly extremely. Will most definitely shot here again
