The Spike’s Tactical upper/lower receiver set (brand part no. STS1512) ships stripped and finished in Flat Dark Earth, giving builders a matched pair of AR-15 receivers as the foundation for a next build. Spike’s builds these to the same high industry standards the brand is known for, so the lower and upper are machined to work together rather than requiring a separately sourced upper. Selling the set stripped keeps cost down and lets builders select their own trigger, safety, and buffer system. It’s a solid, matched foundation for anyone starting a build from scratch.
