Spikes Tactical ST15 Spider Logo Forged Stripped AR-15 Lower Receiver Multi-Caliber

The Spikes Tactical ST15 Spider Logo is a stripped forged lower receiver for AR-15 builds. It is sold without a trigger or other fire-control parts, so it serves as the base for a complete lower assembled by the buyer. The receiver carries the brand's Spider logo and convention-fire and safe selector markings in black without color fill.

The receiver is machined from 7075-T6 aluminum and finished with a Type III hard coat anodized coating in matte black. It has a low shelf for RDIAS use and is marked Multi-Caliber for 5.56x45mm NATO and .223 Remington. The trigger and hammer pin holes measure .154 inch in diameter.
