The Spike’s Tactical Spider Logo Stripped Upper/Lower Receiver Set pairs a forged multi-caliber lower with a matching forged upper receiver (Spike’s Tactical part no. STS1019). Both receivers are 7075-T6 forgings, and the lower carries the Spider logo and bullet pictogram selector markings. The upper comes with the forward assist, ejection port door, door spring and door rod already in place. It is the foundation for anyone assembling a rifle from Spike’s Tactical parts, with the barrel, bolt carrier group and lower parts still to choose.

Key Specifications

• The set includes a forged lower and a forged upper receiver, a matched foundation for a new build.
• The lower is a 7075-T6 forging, a strong aerospace alloy.
• The upper is also 7075-T6, so both halves share the same alloy.
• The lower is multi-caliber, so the caliber comes from the barrel and parts you add.
• The finish is MIL-A-8625F Type III Class 2 hard coat anodize, a coating that resists wear and corrosion.
• The lower has the Spider logo with bullet pictogram selector markings, the Spike’s Tactical signature look.
• The upper includes a forward assist, ejection port door, door spring and door rod, so those small parts are not on your shopping list.
