Product Details
The Spike's Tactical upper and lower receiver set is a solid foundation if you're building your own AR-15 or replacing worn parts. It's mil-spec (that just means it meets military standards for reliability), chambered in 223 Remington/5.56 NATO, and comes in black. You get quality machining here without the fuss, and it's a straightforward choice for someone who wants to do the work themselves or hand it to a gunsmith they trust.
