Never fired Spike's Tactical 9mm Spider stripped lower receiver. I had mounted a Thordsen stock and buffer tube but decided to go with a MAG-ADMP9 instead so I could use my S&W magazines. This will only accept Glock magazines. In person sale at an FFL in lower Dutchess to mid-Westchester County or with additional shipping sent to your FFL. $100 (Spike's has a 4-6 week wait)
The Spike's Tactical Spider 9mm Lower is the perfect foundation for a pistol-caliber carbine build. Fully compatible with most standard AR-15 parts, this lower includes a proprietary magazine catch assembly, ejector factory installed, and last round bolt hold open functionality. Features the Spike’s Spider logo engraved prominently on the left side of the magwell. Spike’s Tactical stripped lowers are made to the highest standards. If you are planning a build or just putting lowers away for a rainy day, you can't go wrong with Spike's lower receivers.
