Designed. Printed. Proven.

At Spectre3D, we don’t chase gimmicks — we build parts that perform. This magazine extension was engineered from the ground up for the Kel-Tec CMR-30 and PMR-30 platforms, chambered in .22 Magnum. Every detail was refined to deliver durability, better handling, and a seamless fit with your factory magazines.

Built the Spectre3D Way

• Engineered Fitment
  No guessing games. Designed specifically for Kel-Tec factory mags to lock up tight and run reliably.

• Carbon Fiber Polymer Strength
  Printed in-house with a carbon fiber–infused polymer that’s rigid, heat resistant, and tough enough for hard use.

• Improved Control
  A more aggressive grip profile for faster reloads and better retention — even when you’re gloved up or in less-than-ideal conditions.

• Spectre3D Styling
  Form follows function, but it still has that clean, aggressive look that complements your Kel-Tec.

• Straightforward Install
  Comes with step-by-step instructions. You’ll need to swap the spring — use an 870 magazine tube spring or similar coil spring at least 8" long with .740" OD for reliable tension and feeding.
