The Spikes Tactical Spider stripped lower receiver (part no. STLS019-CFA) is forged from 7075-T6 aluminum with a black hard-coat anodized finish, marked for multi-caliber use on the standard AR-15 platform. This model carries the recognizable ST Spider logo finished with red color fill for extra contrast against the black anodizing. Sold stripped, it ships with no internal fire-control parts installed, so you supply a lower parts kit, buffer, and stock of your choosing to complete the build.
