Spike's Tactical ST9 Spider 9mm Colt Mag Stripped Lower Receiver

The ST9 is Spike's Tactical's 9mm lower for Colt pattern stick magazines, the classic SMG style 9mm magazine. The magazine well is dedicated to 9mm, so no adapter block is needed, and the proprietary parts it needs come with it. It carries the Spider logo, and the selector markings are bullet pictograms.

It is forged aluminum with a black hard coat anodized finish and a built in trigger guard. It is sold stripped: add a lower parts kit, buffer tube, buffer and the stock or brace you want. If you use a standard buffer, pair it with Spike's 9mm spacer, or run a dedicated 9mm buffer by itself. A good base for a 9mm carbine or pistol build on Colt style magazines.
